+Theo de Raadt <deraadt@openbsd.org> came up with the idea of using
+such a mathematical system to generate more random (yet non-repeating)
+ids to solve the resolver/named problem.  But Niels designed the
+actual system based on the constraints.
+
+Later modified by Damien Miller to wrap the LCG output in a 15-bit
+permutation generator based on a Luby-Rackoff block cipher. This
+ensures the output is non-repeating and preserves the MSB twiddle
+trick, but makes it more resistant to LCG prediction.

+#
+# Note:
+#      - syscall_name corresponds to the name of the syscall, which may differ from
+#        the exported function name (example: the exit syscall is implemented by the _exit()
+#        function, which is not the same as the standard C exit() function which calls it)
+#
+#      - alias_list is optional comma separated list of function aliases.
+#
+#      - The call_id parameter, given that func_name and syscall_name have
+#        been provided, allows the user to specify dispatch style syscalls.
+#        For example, socket() syscall on i386 actually becomes:
+#          socketcall(__NR_socket, 1, *(rest of args on stack)).

+
+/* The main thing to look out for when comparing large blocks is that
+   the loads do not cross a page boundary when loading past the index
+   of the byte with the first difference or the first string-terminator.
+
+   For example, if the strings are identical and the string-terminator
+   is at index k, byte by byte comparison will not load beyond address
+   s1+k and s2+k; word by word comparison may load up to 3 bytes beyond
+   k; double word - up to 7 bytes.  If the load of these bytes crosses
+   a page boundary, it might cause a memory fault (if the page is not mapped)
+   that would not have happened in byte by byte comparison.
+
+   If an address is (double) word aligned, then a load of a (double) word
+   from that address will not cross a page boundary.
+   Therefore, the algorithm below considers word and double-word alignment
+   of strings separately.  */
+
+/* High-level description of the algorithm.
+
+   * The fast path: if both strings are double-word aligned,
+     use LDRD to load two words from each string in every loop iteration.
+   * If the strings have the same offset from a word boundary,
+     use LDRB to load and compare byte by byte until
+     the first string is aligned to a word boundary (at most 3 bytes).
+     This is optimized for quick return on short unaligned strings.
+   * If the strings have the same offset from a double-word boundary,
+     use LDRD to load two words from each string in every loop iteration, as in the fast path.
+   * If the strings do not have the same offset from a double-word boundary,
+     load a word from the second string before the loop to initialize the queue.
+     Use LDRD to load two words from every string in every loop iteration.
+     Inside the loop, load the second word from the second string only after comparing
+     the first word, using the queued value, to guarantee safety across page boundaries.
+   * If the strings do not have the same offset from a word boundary,
+     use LDR and a shift queue. Order of loads and comparisons matters,
+     similarly to the previous case.
+
+   * Use UADD8 and SEL to compare words, and use REV and CLZ to compute the return value.
+   * The only difference between ARM and Thumb modes is the use of CBZ instruction.
+   * The only difference between big and little endian is the use of REV in little endian
+     to compute the return value, instead of MOV.

+
+/* The main thing to look out for when comparing large blocks is that
+   the loads do not cross a page boundary when loading past the index
+   of the byte with the first difference or the first string-terminator.
+
+   For example, if the strings are identical and the string-terminator
+   is at index k, byte by byte comparison will not load beyond address
+   s1+k and s2+k; word by word comparison may load up to 3 bytes beyond
+   k; double word - up to 7 bytes.  If the load of these bytes crosses
+   a page boundary, it might cause a memory fault (if the page is not mapped)
+   that would not have happened in byte by byte comparison.
+
+   If an address is (double) word aligned, then a load of a (double) word
+   from that address will not cross a page boundary.
+   Therefore, the algorithm below considers word and double-word alignment
+   of strings separately.  */
+
+/* High-level description of the algorithm.
+
+   * The fast path: if both strings are double-word aligned,
+     use LDRD to load two words from each string in every loop iteration.
+   * If the strings have the same offset from a word boundary,
+     use LDRB to load and compare byte by byte until
+     the first string is aligned to a word boundary (at most 3 bytes).
+     This is optimized for quick return on short unaligned strings.
+   * If the strings have the same offset from a double-word boundary,
+     use LDRD to load two words from each string in every loop iteration, as in the fast path.
+   * If the strings do not have the same offset from a double-word boundary,
+     load a word from the second string before the loop to initialize the queue.
+     Use LDRD to load two words from every string in every loop iteration.
+     Inside the loop, load the second word from the second string only after comparing
+     the first word, using the queued value, to guarantee safety across page boundaries.
+   * If the strings do not have the same offset from a word boundary,
+     use LDR and a shift queue. Order of loads and comparisons matters,
+     similarly to the previous case.
+
+   * Use UADD8 and SEL to compare words, and use REV and CLZ to compute the return value.
+   * The only difference between ARM and Thumb modes is the use of CBZ instruction.
+   * The only difference between big and little endian is the use of REV in little endian
+     to compute the return value, instead of MOV.

+/* The main thing to look out for when comparing large blocks is that
+   the loads do not cross a page boundary when loading past the index
+   of the byte with the first difference or the first string-terminator.
+
+   For example, if the strings are identical and the string-terminator
+   is at index k, byte by byte comparison will not load beyond address
+   s1+k and s2+k; word by word comparison may load up to 3 bytes beyond
+   k; double word - up to 7 bytes.  If the load of these bytes crosses
+   a page boundary, it might cause a memory fault (if the page is not mapped)
+   that would not have happened in byte by byte comparison.
+
+   If an address is (double) word aligned, then a load of a (double) word
+   from that address will not cross a page boundary.
+   Therefore, the algorithm below considers word and double-word alignment
+   of strings separately.  */
+
+/* High-level description of the algorithm.
+
+   * The fast path: if both strings are double-word aligned,
+     use LDRD to load two words from each string in every loop iteration.
+   * If the strings have the same offset from a word boundary,
+     use LDRB to load and compare byte by byte until
+     the first string is aligned to a word boundary (at most 3 bytes).
+     This is optimized for quick return on short unaligned strings.
+   * If the strings have the same offset from a double-word boundary,
+     use LDRD to load two words from each string in every loop iteration, as in the fast path.
+   * If the strings do not have the same offset from a double-word boundary,
+     load a word from the second string before the loop to initialize the queue.
+     Use LDRD to load two words from every string in every loop iteration.
+     Inside the loop, load the second word from the second string only after comparing
+     the first word, using the queued value, to guarantee safety across page boundaries.
+   * If the strings do not have the same offset from a word boundary,
+     use LDR and a shift queue. Order of loads and comparisons matters,
+     similarly to the previous case.
+
+   * Use UADD8 and SEL to compare words, and use REV and CLZ to compute the return value.
+   * The only difference between ARM and Thumb modes is the use of CBZ instruction.
+   * The only difference between big and little endian is the use of REV in little endian
+     to compute the return value, instead of MOV.

+ *
+ * Using PREFETCH_HINT_PREPAREFORSTORE instead of PREFETCH_STORE
+ * or PREFETCH_STORE_STREAMED offers a large performance advantage
+ * but PREPAREFORSTORE has some special restrictions to consider.
+ *
+ * Prefetch with the 'prepare for store' hint does not copy a memory
+ * location into the cache, it just allocates a cache line and zeros
+ * it out.  This means that if you do not write to the entire cache
+ * line before writing it out to memory some data will get zero'ed out
+ * when the cache line is written back to memory and data will be lost.
+ *
+ * Also if you are using this memcpy to copy overlapping buffers it may
+ * not behave correctly when using the 'prepare for store' hint.  If you
+ * use the 'prepare for store' prefetch on a memory area that is in the
+ * memcpy source (as well as the memcpy destination), then you will get
+ * some data zero'ed out before you have a chance to read it and data will
+ * be lost.
+ *
+ * If you are going to use this memcpy routine with the 'prepare for store'
+ * prefetch you may want to set USE_MEMMOVE_FOR_OVERLAP in order to avoid
+ * the problem of running memcpy on overlapping buffers.
+ *
+ * There are ifdef'ed sections of this memcpy to make sure that it does not
+ * do prefetches on cache lines that are not going to be completely written.
+ * This code is only needed and only used when PREFETCH_STORE_HINT is set to
+ * PREFETCH_HINT_PREPAREFORSTORE.  This code assumes that cache lines are
+ * 32 bytes and if the cache line is larger it will not work correctly.

+   __stack_chk_fail routine is runtime part of stack protector compiler

+
+   Calls are generated by compiler and injected into user functions when
+   -fstack-protector* options are used.
+
+   __stack_chk_fail_local is wrapper for __stack_chk_fail. Compiler generates
+   wrapper calls instead for PIC code only and only on IA32 for optimization
+   purpose (see gcc/config/i386/i386.c). Wrapper body is always included into
+   executable or library. This is the idea of optimization.
+
+   Glibc is doing this via libc_nonshared.a which is linked automatically
+   everytime with libc.so. In bionic we have to bring it within crtfiles
+   because libc.so is real library and not a link script like libc.so at glibc.
+
+   For x86_64 or non-PIC code compiler always generates __stack_chk_fail calls.

+// Contains a thin layer that calls whatever real native allocator
+// has been defined. For the libc shared library, this allows the
+// implementation of a debug malloc that can intercept all of the allocation
+// calls and add special debugging code to attempt to catch allocation
+// errors. All of the debugging code is implemented in a separate shared
+// library that is only loaded when the property "libc.debug.malloc.options"
+// is set to a non-zero value. There are two functions exported to
+// allow ddms, or other external users to get information from the debug
+// allocation.
+//   get_malloc_leak_info: Returns information about all of the known native
+//                         allocations that are currently in use.
+//   free_malloc_leak_info: Frees the data allocated by the call to
+//                          get_malloc_leak_info.

+/*
+ * Issues to be discussed:
+ * - Thread safe-ness must be checked.
+ * - Return values.  There are nonstandard return values defined and used
+ *   in the source code.  This is because RFC2553 is silent about which error
+ *   code must be returned for which situation.
+ * - IPv4 classful (shortened) form.  RFC2553 is silent about it.  XNET 5.2
+ *   says to use inet_aton() to convert IPv4 numeric to binary (alows
+ *   classful form as a result).
+ *   current code - disallow classful form for IPv4 (due to use of inet_pton).
+ * - freeaddrinfo(NULL).  RFC2553 is silent about it.  XNET 5.2 says it is
+ *   invalid.
+ *   current code - SEGV on freeaddrinfo(NULL)
+ * Note:
+ * - We use getipnodebyname() just for thread-safeness.  There's no intent
+ *   to let it do PF_UNSPEC (actually we never pass PF_UNSPEC to
+ *   getipnodebyname().
+ * - The code filters out AFs that are not supported by the kernel,
+ *   when globbing NULL hostname (to loopback, or wildcard).  Is it the right
+ *   thing to do?  What is the relationship with post-RFC2553 AI_ADDRCONFIG
+ *   in ai_flags?
+ * - (post-2553) semantics of AI_ADDRCONFIG itself is too vague.
+ *   (1) what should we do against numeric hostname (2) what should we do
+ *   against NULL hostname (3) what is AI_ADDRCONFIG itself.  AF not ready?
+ *   non-loopback address configured?  global address configured?
+ * - To avoid search order issue, we have a big amount of code duplicate
+ *   from gethnamaddr.c and some other places.  The issues that there's no
+ *   lower layer function to lookup "IPv4 or IPv6" record.  Calling
+ *   gethostbyname2 from getaddrinfo will end up in wrong search order, as
+ *   follows:
+ *	- The code makes use of following calls when asked to resolver with
+ *	  ai_family  = PF_UNSPEC:
+ *		getipnodebyname(host, AF_INET6);
+ *		getipnodebyname(host, AF_INET);
+ *	  This will result in the following queries if the node is configure to
+ *	  prefer /etc/hosts than DNS:
+ *		lookup /etc/hosts for IPv6 address
+ *		lookup DNS for IPv6 address
+ *		lookup /etc/hosts for IPv4 address
+ *		lookup DNS for IPv4 address
+ *	  which may not meet people's requirement.
+ *	  The right thing to happen is to have underlying layer which does
+ *	  PF_UNSPEC lookup (lookup both) and return chain of addrinfos.
+ *	  This would result in a bit of code duplicate with _dns_ghbyname() and
+ *	  friends.

+/* This code implements a small and *simple* DNS resolver cache.
+ *
+ * It is only used to cache DNS answers for a time defined by the smallest TTL
+ * among the answer records in order to reduce DNS traffic. It is not supposed
+ * to be a full DNS cache, since we plan to implement that in the future in a
+ * dedicated process running on the system.
+ *
+ * Note that its design is kept simple very intentionally, i.e.:
+ *
+ *  - it takes raw DNS query packet data as input, and returns raw DNS
+ *    answer packet data as output
+ *
+ *    (this means that two similar queries that encode the DNS name
+ *     differently will be treated distinctly).
+ *
+ *    the smallest TTL value among the answer records are used as the time
+ *    to keep an answer in the cache.
+ *
+ *    this is bad, but we absolutely want to avoid parsing the answer packets
+ *    (and should be solved by the later full DNS cache process).
+ *
+ *  - the implementation is just a (query-data) => (answer-data) hash table
+ *    with a trivial least-recently-used expiration policy.
+ *
+ * Doing this keeps the code simple and avoids to deal with a lot of things
+ * that a full DNS cache is expected to do.
+ *
+ * The API is also very simple:
+ *
+ *   - the client calls _resolv_cache_get() to obtain a handle to the cache.
+ *     this will initialize the cache on first usage. the result can be NULL
+ *     if the cache is disabled.
+ *
+ *   - the client calls _resolv_cache_lookup() before performing a query
+ *
+ *     if the function returns RESOLV_CACHE_FOUND, a copy of the answer data
+ *     has been copied into the client-provided answer buffer.
+ *
+ *     if the function returns RESOLV_CACHE_NOTFOUND, the client should perform
+ *     a request normally, *then* call _resolv_cache_add() to add the received
+ *     answer to the cache.
+ *
+ *     if the function returns RESOLV_CACHE_UNSUPPORTED, the client should
+ *     perform a request normally, and *not* call _resolv_cache_add()
+ *
+ *     note that RESOLV_CACHE_UNSUPPORTED is also returned if the answer buffer
+ *     is too short to accomodate the cached result.

+/** BOUNDED BUFFER FORMATTING
+ **/
+
+/* technical note:
+ *
+ *   the following debugging routines are used to append data to a bounded
+ *   buffer they take two parameters that are:
+ *
+ *   - p : a pointer to the current cursor position in the buffer
+ *         this value is initially set to the buffer's address.
+ *
+ *   - end : the address of the buffer's limit, i.e. of the first byte
+ *           after the buffer. this address should never be touched.
+ *
+ *           IMPORTANT: it is assumed that end > buffer_address, i.e.
+ *                      that the buffer is at least one byte.
+ *
+ *   the _bprint_() functions return the new value of 'p' after the data
+ *   has been appended, and also ensure the following:
+ *
+ *   - the returned value will never be strictly greater than 'end'
+ *
+ *   - a return value equal to 'end' means that truncation occured
+ *     (in which case, end[-1] will be set to 0)
+ *
+ *   - after returning from a _bprint_() function, the content of the buffer
+ *     is always 0-terminated, even in the event of truncation.
+ *
+ *  these conventions allow you to call _bprint_ functions multiple times and
+ *  only check for truncation at the end of the sequence, as in:
+ *
+ *     char  buff[1000], *p = buff, *end = p + sizeof(buff);
+ *
+ *     p = _bprint_c(p, end, '"');

+ *    QUESTION  (variable)
+ *    ANSWER (variable)
+ *    AUTHORITY (variable)
+ *    ADDITIONNAL (variable)
+ *
+ * the HEADER is made of:
+ *
+ *   ID     : 16 : 16-bit unique query identification field
+ *
+ *   QR     :  1 : set to 0 for queries, and 1 for responses
+ *   Opcode :  4 : set to 0 for queries
+ *   AA     :  1 : set to 0 for queries
+ *   TC     :  1 : truncation flag, will be set to 0 in queries
+ *   RD     :  1 : recursion desired
+ *
+ *   RA     :  1 : recursion available (0 in queries)
+ *   Z      :  3 : three reserved zero bits
+ *   RCODE  :  4 : response code (always 0=NOERROR in queries)
+ *
+ *   QDCount: 16 : question count
+ *   ANCount: 16 : Answer count (0 in queries)
+ *   NSCount: 16: Authority Record count (0 in queries)
+ *   ARCount: 16: Additionnal Record count (0 in queries)
+ *
+ * the QUESTION is made of QDCount Question Record (QRs)
+ * the ANSWER is made of ANCount RRs
+ * the AUTHORITY is made of NSCount RRs
+ * the ADDITIONNAL is made of ARCount RRs
+ *
+ * Each Question Record (QR) is made of:
+ *
+ *   QNAME   : variable : Query DNS NAME
+ *   TYPE    : 16       : type of query (A=1, PTR=12, MX=15, AAAA=28, ALL=255)
+ *   CLASS   : 16       : class of query (IN=1)
+ *
+ * Each Resource Record (RR) is made of:
+ *
+ *   NAME    : variable : DNS NAME
+ *   TYPE    : 16       : type of query (A=1, PTR=12, MX=15, AAAA=28, ALL=255)
+ *   CLASS   : 16       : class of query (IN=1)
+ *   TTL     : 32       : seconds to cache this RR (0=none)
+ *   RDLENGTH: 16       : size of RDDATA in bytes
+ *   RDDATA  : variable : RR data (depends on TYPE)
+ *
+ * Each QNAME contains a domain name encoded as a sequence of 'labels'
+ * terminated by a zero. Each label has the following format:
+ *
+ *    LEN  : 8     : lenght of label (MUST be < 64)
+ *    NAME : 8*LEN : label length (must exclude dots)
+ *
+ * A value of 0 in the encoding is interpreted as the 'root' domain and
+ * terminates the encoding. So 'www.android.com' will be encoded as:
+ *
+ *   <3>www<7>android<3>com<0>
+ *
+ * Where <n> represents the byte with value 'n'
+ *
+ * Each NAME reflects the QNAME of the question, but has a slightly more
+ * complex encoding in order to provide message compression. This is achieved
+ * by using a 2-byte pointer, with format:
+ *
+ *    TYPE   : 2  : 0b11 to indicate a pointer, 0b01 and 0b10 are reserved
+ *    OFFSET : 14 : offset to another part of the DNS packet
+ *
+ * The offset is relative to the start of the DNS packet and must point
+ * A pointer terminates the encoding.
+ *
+ * The NAME can be encoded in one of the following formats:
+ *
+ *   - a sequence of simple labels terminated by 0 (like QNAMEs)
+ *   - a single pointer
+ *   - a sequence of simple labels terminated by a pointer
+ *
+ * A pointer shall always point to either a pointer of a sequence of
+ * labels (which can themselves be terminated by either a 0 or a pointer)
+ *
+ * The expanded length of a given domain name should not exceed 255 bytes.
+ *
+ * NOTE: we don't parse the answer packets, so don't need to deal with NAME
+ *       records, only QNAMEs.

+/*
+ * This file defines five types of data structures: singly-linked lists,
+ * lists, simple queues, tail queues, and circular queues.
+ *
+ * A singly-linked list is headed by a single forward pointer. The
+ * elements are singly linked for minimum space and pointer manipulation
+ * overhead at the expense of O(n) removal for arbitrary elements. New
+ * elements can be added to the list after an existing element or at the
+ * head of the list.  Elements being removed from the head of the list
+ * should use the explicit macro for this purpose for optimum
+ * efficiency. A singly-linked list may only be traversed in the forward
+ * direction.  Singly-linked lists are ideal for applications with large
+ * datasets and few or no removals or for implementing a LIFO queue.
+ *
+ * A list is headed by a single forward pointer (or an array of forward
+ * pointers for a hash table header). The elements are doubly linked
+ * so that an arbitrary element can be removed without a need to
+ * traverse the list. New elements can be added to the list before
+ * or after an existing element or at the head of the list. A list
+ * may only be traversed in the forward direction.
+ *
+ * A simple queue is headed by a pair of pointers, one the head of the
+ * list and the other to the tail of the list. The elements are singly
+ * linked to save space, so elements can only be removed from the
+ * head of the list. New elements can be added to the list after
+ * an existing element, at the head of the list, or at the end of the
+ * list. A simple queue may only be traversed in the forward direction.
+ *
+ * A tail queue is headed by a pair of pointers, one to the head of the
+ * list and the other to the tail of the list. The elements are doubly
+ * linked so that an arbitrary element can be removed without a need to
+ * traverse the list. New elements can be added to the list before or
+ * after an existing element, at the head of the list, or at the end of
+ * the list. A tail queue may be traversed in either direction.
+ *
+ * A circle queue is headed by a pair of pointers, one to the head of the
+ * list and the other to the tail of the list. The elements are doubly
+ * linked so that an arbitrary element can be removed without a need to
+ * traverse the list. New elements can be added to the list before or after
+ * an existing element, at the head of the list, or at the end of the list.
+ * A circle queue may be traversed in either direction, but has a more
+ * complex end of list detection.
+ *
+ * For details on the use of these macros, see the queue(3) manual page.

+ *  SYSEXITS.H -- Exit status codes for system programs.
+ *
+ *	This include file attempts to categorize possible error
+ *	exit statuses for system programs, notably delivermail
+ *	and the Berkeley network.
+ *
+ *	Error numbers begin at EX__BASE to reduce the possibility of
+ *	clashing with other exit statuses that random programs may
+ *	already return.  The meaning of the codes is approximately
+ *	as follows:
+ *
+ *	EX_USAGE -- The command was used incorrectly, e.g., with
+ *		the wrong number of arguments, a bad flag, a bad
+ *		syntax in a parameter, or whatever.
+ *	EX_DATAERR -- The input data was incorrect in some way.
+ *		This should only be used for user's data & not
+ *		system files.
+ *	EX_NOINPUT -- An input file (not a system file) did not
+ *		exist or was not readable.  This could also include
+ *		errors like "No message" to a mailer (if it cared
+ *		to catch it).
+ *	EX_NOUSER -- The user specified did not exist.  This might
+ *		be used for mail addresses or remote logins.
+ *	EX_NOHOST -- The host specified did not exist.  This is used
+ *		in mail addresses or network requests.
+ *	EX_UNAVAILABLE -- A service is unavailable.  This can occur
+ *		if a support program or file does not exist.  This
+ *		can also be used as a catchall message when something
+ *		you wanted to do doesn't work, but you don't know
+ *		why.
+ *	EX_SOFTWARE -- An internal software error has been detected.
+ *		This should be limited to non-operating system related
+ *		errors as possible.
+ *	EX_OSERR -- An operating system error has been detected.
+ *		This is intended to be used for such things as "cannot
+ *		fork", "cannot create pipe", or the like.  It includes
+ *		things like getuid returning a user that does not
+ *		exist in the passwd file.
+ *	EX_OSFILE -- Some system file (e.g., /etc/passwd, /var/run/utmp,
+ *		etc.) does not exist, cannot be opened, or has some
+ *		sort of error (e.g., syntax error).
+ *	EX_CANTCREAT -- A (user specified) output file cannot be
+ *		created.
+ *	EX_IOERR -- An error occurred while doing I/O on some file.
+ *	EX_TEMPFAIL -- temporary failure, indicating something that
+ *		is not really an error.  In sendmail, this means
+ *		that a mailer (e.g.) could not create a connection,
+ *		and the request should be reattempted later.
+ *	EX_PROTOCOL -- the remote system returned something that
+ *		was "not possible" during a protocol exchange.
+ *	EX_NOPERM -- You did not have sufficient permission to
+ *		perform the operation.  This is not intended for
+ *		file system problems, which should use EX_NOINPUT or
+ *		EX_CANTCREAT, but rather for higher level permissions.
+ *	EX_CONFIG -- Something was found in an unconfigured or
+ *		misconfigured state.

+Bionic Kernel Header Files
+==========================
+
+Bionic comes with a processed set of all of the uapi Linux kernel headers that
+can safely be included by userland applications and libraries.
+
+These clean headers are automatically generated by several scripts located
+in the 'bionic/kernel/tools' directory. The tools process the original
+unmodified kernel headers in order to get rid of many annoying
+declarations and constructs that usually result in compilation failure.
+
+The 'clean headers' only contain type and macro definitions, with the
+exception of a couple static inline functions used for performance
+reason (e.g. optimized CPU-specific byte-swapping routines).
+
+They can be included from C++, or when compiling code in strict ANSI mode.
+They can be also included before or after any Bionic C library header.
+
+Description of the directories involved in generating the parsed kernel headers:
+
+  * 'external/kernel-headers/original/'
+    Contains the uapi kernel headers found in the android kernel. Note this
+    also includes the header files that are generated by building the kernel
+    sources.
+
+  * 'bionic/libc/kernel/uapi'
+    Contains the cleaned kernel headers and mirrors the directory structure
+    in 'external/kernel-headers/original/uapi/'.
+
+  * 'bionic/libc/kernel/tools'
+    Contains various Python and shell scripts used to get and re-generate
+    the headers.
+
+The tools to get/parse the headers:
+
+  * tools/generate_uapi_headers.sh
+    Checks out the android kernel and generates all uapi header files.
+    copies all the changed files into external/kernel-headers.
+
+  * tools/clean_header.py
+    Prints the clean version of a given kernel header. With the -u option,
+    this will also update the corresponding clean header file if its
+    content has changed. You can also process more than one file with -u.
+
+  * tools/update_all.py
+    Automatically update all clean headers from the content of
+    'external/kernel-headers/original'.
+
+How To Update The Headers
+=========================
+
+IMPORTANT IMPORTANT:
+
+WHEN UPDATING THE HEADERS, ALWAYS CHECK THAT THE NEW CLEAN HEADERS DO
+NOT BREAK THE KERNEL <-> USER ABI, FOR EXAMPLE BY CHANGING THE SIZE
+OF A GIVEN TYPE. THIS TASK CANNOT BE EASILY AUTOMATED AT THE MOMENT.
+
+Download the Linux kernel source code:
+
+  > mkdir kernel_src
+  > cd kernel_src
+  kernel_src> git clone git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git
+
+Then checkout the stable tag for the new kernel headers to import:
+
+  kernel_src> cd linux-stable
+  kernel_src/linux-stable> git checkout tags/vXXX
+
+Before running the command to import the headers, make sure that you have
+done a lunch TARGET. The script uses a variable set by the lunch command
+to determine which directory to use as the destination directory.
+
+After running lunch, run this command to import the headers into the android
+source tree:
+
+  bionic/libc/kernel/tools/generate_uapi_headers.sh --use-kernel-dir kernel_src
+
+Next, run this command to copy the parsed files to bionic/libc/kernel/uapi:
+
+  bionic/libc/kernel/tools/update_all.py
+
+Finally, run this command to regenerate the syscalls list:
+
+  bionic/libc/tools/gensyscalls.py
+
+After this, you will need to build/test the tree to make sure that these
+changes do not introduce any errors.

+The files under the uapi directory are android kernel uapi header files that
+exist in android kernels, but have not been upstreamed into the regular
+kernel.
+
+None of these files will get updated automatically, and are frozen at their
+current value.
+
+The files under the scsi directory are frozen copies of kernel scsi headers.
+Linux's scsi headers are a mix of userspace-facing and kernel-facing
+declarations that can't be directly used by userspace. The glibc
+maintainers manually copy-and-pasted these definitions into their own
+scsi headers and haven't substantially updated them in 15 years. The
+musl libc project has a similar set of definitions in its scsi headers.
+
+These files are actually maintained in external/kernel-headers/modified/scsi.
+Any modification should first be made there then copied into the scsi
+directory.

+#!/usr/bin/env python
+
+#------------------------------------------------------------------------------
+# Description of the header clean process
+#------------------------------------------------------------------------------
+# Here is the list of actions performed by this script to clean the original
+# kernel headers.
+#
+# 1. Optimize well-known macros (e.g. __KERNEL__, __KERNEL_STRICT_NAMES)
+#
+#     This pass gets rid of everything that is guarded by a well-known macro
+#     definition. This means that a block like:
+#
+#        #ifdef __KERNEL__
+#        ....
+#        #endif
+#
+#     Will be totally omitted from the output. The optimizer is smart enough to
+#     handle all complex C-preprocessor conditional expression appropriately.
+#     This means that, for example:
+#
+#        #if defined(__KERNEL__) || defined(FOO)
+#        ...
+#        #endif
+#
+#     Will be transformed into:
+#
+#        #ifdef FOO
+#        ...
+#        #endif
+#
+#     See tools/defaults.py for the list of well-known macros used in this pass,
+#     in case you need to update it in the future.
+#
+#     Note that this also removes any reference to a kernel-specific
+#     configuration macro like CONFIG_FOO from the clean headers.
+#
+#
+# 2. Remove variable and function declarations:
+#
+#   This pass scans non-directive text and only keeps things that look like a
+#   typedef/struct/union/enum declaration. This allows us to get rid of any
+#   variables or function declarations that should only be used within the
+#   kernel anyway (and which normally *should* be guarded by an #ifdef
+#   __KERNEL__ ...  #endif block, if the kernel writers were not so messy).
+#
+#   There are, however, a few exceptions: it is seldom useful to keep the
+#   definition of some static inline functions performing very simple
+#   operations. A good example is the optimized 32-bit byte-swap function
+#   found in:
+#
+#     arch-arm/asm/byteorder.h
+#
+#   The list of exceptions is in tools/defaults.py in case you need to update
+#   it in the future.
+#
+#   Note that we do *not* remove macro definitions, including these macro that
+#   perform a call to one of these kernel-header functions, or even define other
+#   functions. We consider it safe since userland applications have no business
+#   using them anyway.
+#
+#
+# 3. Add a standard disclaimer:
+#
+#   The message:
+#
+#   /* WARNING: DO NOT EDIT, AUTO-GENERATED CODE - SEE TOP FOR INSTRUCTIONS */
+#
+#   Is prepended to each generated header.

+Malloc Debug
+============
+
+Malloc debug is a method of debugging native memory problems. It can help
+detect memory corruption, memory leaks, and use after free issues.
+
+This documentation describes how to enable this feature on Android N or later
+versions of the Android OS.
+
+The documentation for malloc debug on older versions of Android is
+[here](README_marshmallow_and_earlier.md).
+
+In order to enable malloc debug, you must be able to set special system
+properties using the setprop command from the shell. This requires the
+ability to run as root on the device.
+
+When malloc debug is enabled, it works by adding a shim layer that replaces
+the normal allocation calls. The replaced calls are:
+
+* `malloc`
+* `free`
+* `calloc`
+* `realloc`
+* `posix_memalign`
+* `memalign`
+* `malloc_usable_size`
+
+On 32 bit systems, these two deprecated functions are also replaced:
+
+* `pvalloc`
+* `valloc`
+
+Any errors detected by the library are reported in the log.
+
+Controlling Malloc Debug Behavior
+---------------------------------
+Malloc debug is controlled by individual options. Each option can be enabled
+individually, or in a group of other options. Every single option can be
+combined with every other option.
+
+Option Descriptions
+-------------------
+### front\_guard[=SIZE\_BYTES]
+Enables a small buffer placed before the allocated data. This is an attempt
+to find memory corruption occuring to a region before the original allocation.
+On first allocation, this front guard is written with a specific pattern (0xaa).
+When the allocation is freed, the guard is checked to verify it has not been
+modified. If any part of the front guard is modified, an error will be reported
+in the log indicating what bytes changed.
+
+If the backtrace option is also enabled, then any error message will include
+the backtrace of the allocation site.
+
+If SIZE\_BYTES is present, it indicates the number of bytes in the guard.
+The default is 32 bytes, the max bytes is 16384. SIZE\_BYTES will be
+padded so that it is a multiple of 8 bytes on 32 bit systems and 16 bytes
+on 64 bit systems to make sure that the allocation returned is aligned
+properly.
+
+This option adds a special header to all allocations that contains the guard
+and information about the original allocation.
+
+Example error:
+
+    04-10 12:00:45.621  7412  7412 E malloc_debug: +++ ALLOCATION 0x12345678 SIZE 100 HAS A CORRUPTED FRONT GUARD
+    04-10 12:00:45.622  7412  7412 E malloc_debug:   allocation[-32] = 0x00 (expected 0xaa)
+    04-10 12:00:45.622  7412  7412 E malloc_debug:   allocation[-15] = 0x02 (expected 0xaa)
+
+### rear\_guard[=SIZE\_BYTES]
+Enables a small buffer placed after the allocated data. This is an attempt
+to find memory corruption occuring to a region after the original allocation.
+On first allocation, this rear guard is written with a specific pattern (0xbb).
+When the allocation is freed, the guard is checked to verify it has not been
+modified. If any part of the rear guard is modified, an error will be reported
+in the log indicating what bytes changed.
+
+If SIZE\_BYTES is present, it indicates the number of bytes in the guard.
+The default is 32 bytes, the max bytes is 16384.
+
+This option adds a special header to all allocations that contains
+information about the original allocation.
+
+Example error:
+
+    04-10 12:00:45.621  7412  7412 E malloc_debug: +++ ALLOCATION 0x12345678 SIZE 100 HAS A CORRUPTED REAR GUARD
+    04-10 12:00:45.622  7412  7412 E malloc_debug:   allocation[130] = 0xbf (expected 0xbb)
+    04-10 12:00:45.622  7412  7412 E malloc_debug:   allocation[131] = 0x00 (expected 0xbb)
+
+### guard[=SIZE\_BYTES]
+Enables both a front guard and a rear guard on all allocations.
+
+If SIZE\_BYTES is present, it indicates the number of bytes in both guards.
+The default is 32 bytes, the max bytes is 16384.
+
+### backtrace[=MAX\_FRAMES]
+Enable capturing the backtrace of each allocation site.
+This option will slow down allocations by an order of magnitude. If the
+system runs too slowly with this option enabled, decreasing the maximum number
+of frames captured will speed the allocations up.
+
+Note that any backtrace frames that occur within the malloc backtrace library
+itself are not recorded.
+
+If MAX\_FRAMES is present, it indicates the maximum number of frames to
+capture in a backtrace. The default is 16 frames, the maximumum value
+this can be set to is 256.
+
+This option adds a special header to all allocations that contains the
+backtrace and information about the original allocation.
+
+### backtrace\_enable\_on\_signal[=MAX\_FRAMES]
+Enable capturing the backtrace of each allocation site. If the
+backtrace capture is toggled when the process receives the signal
+SIGRTMAX - 19 (which is 45 on most Android devices). When this
+option is used alone, backtrace capture starts out disabled until the signal
+is received. If both this option and the backtrace option are set, then
+backtrace capture is enabled until the signal is received.
+
+If MAX\_FRAMES is present, it indicates the maximum number of frames to
+capture in a backtrace. The default is 16 frames, the maximumum value
+this can be set to is 256.
+
+This option adds a special header to all allocations that contains the
+backtrace and information about the original allocation.
+
+### fill\_on\_alloc[=MAX\_FILLED\_BYTES]
+Any allocation routine, other than calloc, will result in the allocation being
+filled with the value 0xeb. When doing a realloc to a larger size, the bytes
+above the original usable size will be set to 0xeb.
+
+If MAX\_FILLED\_BYTES is present, it will only fill up to the specified number
+of bytes in the allocation. The default is to fill the entire allocation.
+
+### fill\_on\_free[=MAX\_FILLED\_BYTES]
+When an allocation is freed, fill it with 0xef.
+
+If MAX\_FILLED\_BYTES is present, it will only fill up to the specified number
+of bytes in the allocation. The default is to fill the entire allocation.
+
+### fill[=MAX\_FILLED\_BYTES]
+This enables both the fill\_on\_alloc option and the fill\_on\_free option.
+
+If MAX\_FILLED\_BYTES is present, it will only fill up to the specified number
+of bytes in the allocation. The default is to fill the entire allocation.
+
+### expand\_alloc[=EXPAND\_BYTES]
+Add an extra amount to allocate for every allocation.
+
+If XX is present, it is the number of bytes to expand the allocation by.
+The default is 16 bytes, the max bytes is 16384.
+
+### free\_track[=ALLOCATION\_COUNT]
+When a pointer is freed, do not free the memory right away, but add it to
+a list of freed allocations. In addition to being added to the list, the
+entire allocation is filled with the value 0xef, and the backtrace at
+the time of the free is recorded. The backtrace recording is completely
+separate from the backtrace option, and happens automatically if this
+option is enabled. By default, a maximum of 16 frames will be recorded,
+but this value can be changed using the free\_track\_backtrace\_num\_frames
+option. It can also be completely disabled by setting the option to zero.
+See the full description of this option below.
+
+When the list is full, an allocation is removed from the list and is
+checked to make sure that none of the contents have been modified since
+being placed on the list. When the program terminates, all of the allocations
+left on the list are verified.
+
+If ALLOCATION\_COUNT is present, it indicates the total number of allocations
+in the list. The default is to record 100 freed allocations, the max
+allocations to record is 16384.
+
+This option adds a special header to all allocations that contains
+information about the original allocation.
+
+Example error:
+
+    04-15 12:00:31.304  7412  7412 E malloc_debug: +++ ALLOCATION 0x12345678 USED AFTER FREE
+    04-15 12:00:31.305  7412  7412 E malloc_debug:   allocation[20] = 0xaf (expected 0xef)
+    04-15 12:00:31.305  7412  7412 E malloc_debug:   allocation[99] = 0x12 (expected 0xef)
+    04-15 12:00:31.305  7412  7412 E malloc_debug: Backtrace at time of free:
+    04-15 12:00:31.305  7412  7412 E malloc_debug:           #00  pc 00029310  /system/lib/libc.so
+    04-15 12:00:31.305  7412  7412 E malloc_debug:           #01  pc 00021438  /system/lib/libc.so (newlocale+160)
+    04-15 12:00:31.305  7412  7412 E malloc_debug:           #02  pc 000a9e38  /system/lib/libc++.so
+    04-15 12:00:31.305  7412  7412 E malloc_debug:           #03  pc 000a28a8  /system/lib/libc++.so
+
+In addition, there is another type of error message that can occur if
+an allocation has a special header applied, and the header is corrupted
+before the verification occurs. This is the error message that will be found
+in the log:
+
+    04-15 12:00:31.604  7412  7412 E malloc_debug: +++ ALLOCATION 0x12345678 HAS CORRUPTED HEADER TAG 0x1cc7dc00 AFTER FREE
+
+### free\_track\_backtrace\_num\_frames[=MAX\_FRAMES]
+This option only has meaning if free\_track is set. It indicates how many
+backtrace frames to capture when an allocation is freed.
+
+If MAX\_FRAMES is present, it indicates the number of frames to capture.
+If the value is set to zero, then no backtrace will be captured when the
+allocation is freed. The default is to record 16 frames, the max number of
+frames to to record is 256.
+
+### leak\_track
+Track all live allocations. When the program terminates, all of the live
+allocations will be dumped to the log. If the backtrace option was enabled,
+then the log will include the backtrace of the leaked allocations. This
+option is not useful when enabled globally because a lot of programs do not
+free everything before the program terminates.
+
+This option adds a special header to all allocations that contains
+information about the original allocation.
+
+Example leak error found in the log:
+
+    04-15 12:35:33.304  7412  7412 E malloc_debug: +++ APP leaked block of size 100 at 0x2be3b0b0 (leak 1 of 2)

+### record\_allocs[=TOTAL\_ENTRIES]
+Keep track of every allocation/free made on every thread and dump them
+to a file when the signal SIGRTMAX - 18 (which is 46 on most Android devices)
+is received.
+
+If TOTAL\_ENTRIES is set, then it indicates the total number of
+allocation/free records that can be retained. If the number of records
+reaches the TOTAL\_ENTRIES value, then any further allocations/frees are
+not recorded. The default value is 8,000,000 and the maximum value this
+can be set to is 50,000,000.
+
+Once the signal is received, and the current records are written to the
+file, all current records are deleted. Any allocations/frees occuring while
+the data is being dumped to the file are ignored.
+
+**NOTE**: This option is not available until the O release of Android.
+
+The allocation data is written in a human readable format. Every line begins
+with the THREAD\_ID returned by gettid(), which is the thread that is making
+the allocation/free. If a new thread is created, no special line is added
+to the file. However, when a thread completes, a special entry is added to
+the file indicating this.
+
+The thread complete line is:
+
+**THREAD\_ID**: thread\_done 0x0

+
+    187: thread_done 0x0

+
+This indicates that a function (malloc\_usable\_size) was called with
+a pointer that is either not allocated memory, or that the memory of

+
+As with the other error message, the function in parenthesis is the
+function that was called with the bad pointer.

+Examples
+========
+Enable backtrace tracking of all allocation for all processes:
+
+    adb shell stop
+    adb shell setprop libc.debug.malloc.options backtrace
+    adb shell start
+
+Enable backtrace tracking for a specific process (ls):
+
+    adb shell setprop libc.debug.malloc.options backtrace
+    adb shell setprop libc.debug.malloc.program ls
+    adb shell ls
+
+Enable backtrace tracking for the zygote and zygote based processes:
+
+    adb shell stop
+    adb shell setprop libc.debug.malloc.program app_process
+    adb shell setprop libc.debug.malloc.options backtrace
+    adb shell start
+
+Enable multiple options (backtrace and guards):
+
+    adb shell stop
+    adb shell setprop libc.debug.malloc.options "\"backtrace guards\""
+    adb shell start
+
+Enable malloc debug when multiple processes have the same name. This method
+can be used to enable malloc debug for only a very specific process if
+multiple processes have the same name.
+
+Note: The double quotes in the adb shell command are necessary. Otherwise,
+the setprop command will fail since the backtrace guards options will look
+like two arguments instead of one.

+Native Memory Tracking using libc Callbacks
+-------------------------------------------
+Malloc debug can be used to get information on all of the live allocations
+in a process. The libc library in Android exports two calls that can be
+used to gather this data from a process. This tracking can be enabled using
+either the backtrace option or the backtrace\_enabled\_on\_signal option.
+
+The function to gather the data:
+
+`extern "C" void get_malloc_leak_info(uint8_t** info, size_t* overall_size, size_t* info_size, size_t* total_memory, size_t* backtrace_size);`
+
+*info* is set to a buffer allocated by the call that contains all of
+the allocation information.
+*overall\_size* is set to the total size of the buffer returned. If this
+*info\_size*
+value is zero, then there are no allocation being tracked.
+*total\_memory* is set to the sum of all allocation sizes that are live at
+the point of the function call. This does not include the memory allocated
+by the malloc debug library itself.
+*backtrace\_size* is set to the maximum number of backtrace entries
+that are present for each allocation.
+
+In order to free the buffer allocated by the function, call:
+
+`extern "C" void free_malloc_leak_info(uint8_t* info);`
+
+### Format of info Buffer
+    size_t size_of_original_allocation
+    size_t num_backtrace_frames
+    uintptr_t pc1
+    uintptr_t pc2
+    uintptr_t pc3
+    .
+    .
+    .
+
+The number of *uintptr\_t* values is determined by the value
+*backtrace\_size* as returned by the original call to
+*get\_malloc\_leak\_info*. This value is not variable, it is the same
+for all the returned data. The value
+*num\_backtrace\_frames* contains the real number of frames found. The
+extra frames are set to zero. Each *uintptr\_t* is a pc of the callstack.
+The calls from within the malloc debug library are automatically removed.
+
+For 32 bit systems, *size\_t* and *uintptr\_t* are both 4 byte values.
+
+For 64 bit systems, *size\_t* and *uintptr\_t* are both 8 byte values.
+
+The total number of these structures returned in *info* is
+*overall\_size* divided by *info\_size*.
+
+Note, the size value in each allocation data structure will have bit 31 set
+if this allocation was created by the Zygote process. This helps to distinguish
+between native allocations created by the application.

+Malloc Debug
+============
+
+Malloc debug is a method of debugging native memory problems. It can help
+detect memory corruption, memory leaks, and use after free issues.
+
+This documentation describes how to enable this feature on versions of
+the Android OS, Marshmallow or older. Note: malloc debug was full of bugs
+and was not fully functional until KitKat, so using it on a version older
+than that is not guaranteed to work at all.
+
+The documentation for malloc debug on newer versions of Android is
+[here](README.md).
+
+On these old versions of the OS, you must be able to set system properties
+using the setprop command from the shell. This requires the ability to
+run as root on the device.
+
+When malloc debug is enabled, it works by adding a shim layer that replaces
+the normal allocation calls. The replaced calls are:
+
+* `malloc`
+* `free`
+* `calloc`
+* `realloc`
+* `posix_memalign`
+* `memalign`
+* `malloc_usable_size`
+
+On 32 bit systems, these two deprecated functions are also replaced:
+
+* `pvalloc`
+* `valloc`
+
+Any errors detected by the library are reported in the log.
+
+Controlling Malloc Debug Behavior
+---------------------------------
+Malloc debug is controlled by a system property that takes a numeric value
+named libc.debug.malloc. It has only a few distinct modes that enables a
+set of different malloc debug checks at once.
+
+Value 1
+--------
+When enabled, this value creates a special header to all allocations
+that contains information about the allocation.
+
+### Backtrace at Allocation Creation
+Enable capturing the backtrace of each allocation site. Only the
+first 16 frames of the backtrace will be captured.
+This option will slow down allocations by an order of magnitude, and
+might cause timeouts when trying to start a device.
+
+### Track Live Allocations
+All of the currently live allocations will be tracked and can be retrieved
+by a call to get\_malloc\_leak\_info (see README\_api.md for details).
+
+Note: If multiple allocations have the same exact backtrace, then only one
+entry is returned in the list.
+
+Value 5
+-------
+When enabled, this value does not create a special header. It only modifies
+the content of allocations.
+
+Whenever an allocation is created, initialize the data with a known
+pattern (0xeb). This does not happen for the calloc calls.
+Whenever an allocation is freed, write a known pattern over the data (0xef).
+
+Value 10
+--------
+When enabled, this value creates a special header to all allocations
+that contains information about the allocation.
+
+This value enables everything enabled with value 1 plus these other options.
+
+### Allocation Guards
+A 32 byte buffer is placed before the returned allocation (known as
+a front guard). This buffer is filled with the pattern (0xaa). In addition,
+a 32 byte buffer is placed after the data for the returned allocation (known
+as a rear guard). This buffer is filled with the pattern (0xbb).
+
+When the allocation is freed, both of these guards are verified to contain
+the expected patterns. If not, then an error message is printed to the log.
+
+### Free Memory Tracking
+When a pointer is freed, do not free the memory right away, but add it to
+a list of freed allocations. In addition to being added to the list, the
+entire allocation is filled with the value 0xef, and the backtrace at
+the time of the free is recorded. As with the backtrace on allocation,
+only up to 16 frames will be recorded.
+
+When the list of freed allocations reaches 100, the oldest allocation
+on the list is removed and verified that it still contains the pattern 0xef.
+If the entire allocation is not filled with this value, an error is printed
+to the log.
+
+### Log Leaks
+When the program completes, all of the allocations that are still live
+are printed to the log as leaks. This isn't very useful since it tends
+to display a lot of false positive because many programs do not free
+everything before terminating.
+
+Option 20
+---------
+Do not use this option value, it only works on the emulator. It has not
+been verified, so it may or may not work.
+
+Enable on Certain Processes
+---------------------------
+Using the special system property, libc.debug.malloc.program, will
+cause malloc debug to only be used on processes with that name. For example,
+if the property is set to ls, then only the program named ls will have malloc
+debug enabled.
+
+Examples
+========
+Enable malloc debug for all allocations for all processes:
+
+    adb shell stop
+    adb shell setprop libc.debug.malloc 1
+    adb shell start
+
+Enable malloc debug for a particular process:
+
+    adb shell setprop libc.debug.malloc.program ls
+    adb shell setprop libc.debug.malloc 10
+    adb shell ls /data/local/tmp

+ * random.c:
+ *
+ * An improved random number generation package.  In addition to the standard
+ * rand()/srand() like interface, this package also has a special state info
+ * interface.  The initstate() routine is called with a seed, an array of
+ * bytes, and a count of how many bytes are being passed in; this array is
+ * then initialized to contain information for random number generation with
+ * that much state information.  Good sizes for the amount of state
+ * information are 32, 64, 128, and 256 bytes.  The state can be switched by
+ * calling the setstate() routine with the same array as was initiallized
+ * with initstate().  By default, the package runs with 128 bytes of state
+ * information and generates far better random numbers than a linear
+ * congruential generator.  If the amount of state information is less than
+ * 32 bytes, a simple linear congruential R.N.G. is used.
+ *
+ * Internally, the state information is treated as an array of ints; the
+ * zeroeth element of the array is the type of R.N.G. being used (small
+ * integer); the remainder of the array is the state information for the
+ * R.N.G.  Thus, 32 bytes of state information will give 7 ints worth of
+ * state information, which will allow a degree seven polynomial.  (Note:
+ * the zeroeth word of state information also has some other information
+ * stored in it -- see setstate() for details).
+ * 
+ * The random number generation technique is a linear feedback shift register
+ * approach, employing trinomials (since there are fewer terms to sum up that
+ * way).  In this approach, the least significant bit of all the numbers in
+ * the state table will act as a linear feedback shift register, and will
+ * have period 2^deg - 1 (where deg is the degree of the polynomial being
+ * used, assuming that the polynomial is irreducible and primitive).  The
+ * higher order bits will have longer periods, since their values are also
+ * influenced by pseudo-random carries out of the lower bits.  The total
+ * period of the generator is approximately deg*(2**deg - 1); thus doubling
+ * the amount of state information has a vast influence on the period of the
+ * generator.  Note: the deg*(2**deg - 1) is an approximation only good for
+ * large deg, when the period of the shift register is the dominant factor.
+ * With deg equal to seven, the period is actually much longer than the
+ * 7*(2**7 - 1) predicted by this formula.
+ *
+ * Modified 28 December 1994 by Jacob S. Rosenberg.
+ * The following changes have been made:
+ * All references to the type u_int have been changed to unsigned long.
+ * All references to type int have been changed to type long.  Other
+ * cleanups have been made as well.  A warning for both initstate and
+ * setstate has been inserted to the effect that on Sparc platforms
+ * the 'arg_state' variable must be forced to begin on word boundaries.
+ * This can be easily done by casting a long integer array to char *.
+ * The overall logic has been left STRICTLY alone.  This software was
+ * tested on both a VAX and Sun SpacsStation with exactly the same
+ * results.  The new version and the original give IDENTICAL results.
+ * The new version is somewhat faster than the original.  As the
+ * documentation says:  "By default, the package runs with 128 bytes of
+ * state information and generates far better random numbers than a linear
+ * congruential generator.  If the amount of state information is less than
+ * 32 bytes, a simple linear congruential R.N.G. is used."  For a buffer of
+ * 128 bytes, this new version runs about 19 percent faster and for a 16
+ * byte buffer it is about 5 percent faster.
+ *
+ * Modified 07 January 2002 by Jason R. Thorpe.
+ * The following changes have been made:
+ * All the references to "long" have been changed back to "int".  This
+ * fixes memory corruption problems on LP64 platforms.
+ */
+
+/*
+ * For each of the currently supported random number generators, we have a
+ * break value on the amount of state information (you need at least this
+ * many bytes of state info to support this random number generator), a degree
+ * for the polynomial (actually a trinomial) that the R.N.G. is based on, and
+ * the separation between the two lower order coefficients of the trinomial.

+/* dtoa for IEEE arithmetic (dmg): convert double to ASCII string.
+ *
+ * Inspired by "How to Print Floating-Point Numbers Accurately" by
+ * Guy L. Steele, Jr. and Jon L. White [Proc. ACM SIGPLAN '90, pp. 112-126].
+ *
+ * Modifications:
+ *	1. Rather than iterating, we use a simple numeric overestimate
+ *	   to determine k = floor(log10(d)).  We scale relevant
+ *	   quantities using O(log2(k)) rather than O(k) multiplications.
+ *	2. For some modes > 2 (corresponding to ecvt and fcvt), we don't
+ *	   try to generate digits strictly left to right.  Instead, we
+ *	   compute with fewer bits and propagate the carry if necessary
+ *	   when rounding the final digit up.  This is often faster.
+ *	3. Under the assumption that input will be rounded nearest,
+ *	   mode 0 renders 1e23 as 1e23 rather than 9.999999999999999e22.
+ *	   That is, we allow equality in stopping tests when the
+ *	   round-nearest rule will give the same floating-point value
+ *	   as would satisfaction of the stopping test with strict
+ *	   inequality.
+ *	4. We remove common factors of powers of 2 from relevant
+ *	   quantities.
+ *	5. When converting floating-point integers less than 1e16,
+ *	   we use floating-point arithmetic rather than resorting
+ *	   to multiple-precision integers.
+ *	6. When asked to produce fewer than 15 digits, we first try
+ *	   to get by with floating-point arithmetic; we resort to
+ *	   multiple-precision integer arithmetic only if we cannot
+ *	   guarantee that the floating-point calculation has given
+ *	   the correctly rounded result.  For k requested digits and
+ *	   "uniformly" distributed input, the probability is
+ *	   something like 10^(k-15) that we must resort to the Long
+ *	   calculation.

+/* dtoa for IEEE arithmetic (dmg): convert double to ASCII string.
+ *
+ * Inspired by "How to Print Floating-Point Numbers Accurately" by
+ * Guy L. Steele, Jr. and Jon L. White [Proc. ACM SIGPLAN '90, pp. 112-126].
+ *
+ * Modifications:
+ *	1. Rather than iterating, we use a simple numeric overestimate
+ *	   to determine k = floor(log10(d)).  We scale relevant
+ *	   quantities using O(log2(k)) rather than O(k) multiplications.
+ *	2. For some modes > 2 (corresponding to ecvt and fcvt), we don't
+ *	   try to generate digits strictly left to right.  Instead, we
+ *	   compute with fewer bits and propagate the carry if necessary
+ *	   when rounding the final digit up.  This is often faster.
+ *	3. Under the assumption that input will be rounded nearest,
+ *	   mode 0 renders 1e23 as 1e23 rather than 9.999999999999999e22.
+ *	   That is, we allow equality in stopping tests when the
+ *	   round-nearest rule will give the same floating-point value
+ *	   as would satisfaction of the stopping test with strict
+ *	   inequality.
+ *	4. We remove common factors of powers of 2 from relevant
+ *	   quantities.
+ *	5. When converting floating-point integers less than 1e16,
+ *	   we use floating-point arithmetic rather than resorting
+ *	   to multiple-precision integers.
+ *	6. When asked to produce fewer than 15 digits, we first try
+ *	   to get by with floating-point arithmetic; we resort to
+ *	   multiple-precision integer arithmetic only if we cannot
+ *	   guarantee that the floating-point calculation has given
+ *	   the correctly rounded result.  For k requested digits and
+ *	   "uniformly" distributed input, the probability is
+ *	   something like 10^(k-15) that we must resort to the Long
+ *	   calculation.

+ * of) Intel 80x87 arithmetic, the call
+ *	_control87(PC_53, MCW_PC);
+ * does this with many compilers.  Whether this or another call is
+ * appropriate depends on the compiler; for this to work, it may be

+
+/* strtod for IEEE-, VAX-, and IBM-arithmetic machines.
+ *
+ * This strtod returns a nearest machine number to the input decimal
+ * string (or sets errno to ERANGE).  With IEEE arithmetic, ties are
+ * broken by the IEEE round-even rule.  Otherwise ties are broken by
+ * biased rounding (add half and chop).
+ *
+ * Inspired loosely by William D. Clinger's paper "How to Read Floating
+ * Point Numbers Accurately" [Proc. ACM SIGPLAN '90, pp. 112-126].
+ *
+ * Modifications:
+ *
+ *	1. We only require IEEE, IBM, or VAX double-precision
+ *		arithmetic (not IEEE double-extended).
+ *	2. We get by with floating-point arithmetic in a case that
+ *		Clinger missed -- when we're computing d * 10^n
+ *		for a small integer d and the integer n is not too
+ *		much larger than 22 (the maximum integer k for which
+ *		we can represent 10^k exactly), we may be able to
+ *		compute (d*10^k) * 10^(e-k) with just one roundoff.
+ *	3. Rather than a bit-at-a-time adjustment of the binary
+ *		result in the hard case, we use floating-point
+ *		arithmetic to determine the adjustment to within
+ *		one bit; only in really hard cases do we need to
+ *		compute a second residual.
+ *	4. Because of 3., we don't need a large table of powers of 10
+ *		for ten-to-e (just some small tables, e.g. of 10^k
+ *		for 0 <= k <= 22).

+/*
+ * #define IEEE_8087 for IEEE-arithmetic machines where the least
+ *	significant byte has the lowest address.
+ * #define IEEE_MC68k for IEEE-arithmetic machines where the most
+ *	significant byte has the lowest address.
+ * #define Long int on machines with 32-bit ints and 64-bit longs.
+ * #define Sudden_Underflow for IEEE-format machines without gradual
+ *	underflow (i.e., that flush to zero on underflow).
+ * #define IBM for IBM mainframe-style floating-point arithmetic.
+ * #define VAX for VAX-style floating-point arithmetic (D_floating).
+ * #define No_leftright to omit left-right logic in fast floating-point
+ *	computation of dtoa and gdtoa.  This will cause modes 4 and 5 to be
+ *	treated the same as modes 2 and 3 for some inputs.
+ * #define Check_FLT_ROUNDS if FLT_ROUNDS can assume the values 2 or 3.
+ * #define RND_PRODQUOT to use rnd_prod and rnd_quot (assembly routines
+ *	that use extended-precision instructions to compute rounded
+ *	products and quotients) with IBM.
+ * #define ROUND_BIASED for IEEE-format with biased rounding and arithmetic
+ *	that rounds toward +Infinity.
+ * #define ROUND_BIASED_without_Round_Up for IEEE-format with biased
+ *	rounding when the underlying floating-point arithmetic uses
+ *	unbiased rounding.  This prevent using ordinary floating-point
+ *	arithmetic when the result could be computed with one rounding error.
+ * #define Inaccurate_Divide for IEEE-format with correctly rounded
+ *	products but inaccurate quotients, e.g., for Intel i860.
+ * #define NO_LONG_LONG on machines that do not have a "long long"
+ *	integer type (of >= 64 bits).  On such machines, you can
+ *	#define Just_16 to store 16 bits per 32-bit Long when doing
+ *	high-precision integer arithmetic.  Whether this speeds things
+ *	up or slows things down depends on the machine and the number
+ *	being converted.  If long long is available and the name is
+ *	something other than "long long", #define Llong to be the name,
+ *	and if "unsigned Llong" does not work as an unsigned version of
+ *	Llong, #define #ULLong to be the corresponding unsigned type.
+ * #define KR_headers for old-style C function headers.
+ * #define Bad_float_h if your system lacks a float.h or if it does not
+ *	define some or all of DBL_DIG, DBL_MAX_10_EXP, DBL_MAX_EXP,
+ *	FLT_RADIX, FLT_ROUNDS, and DBL_MAX.
+ * #define MALLOC your_malloc, where your_malloc(n) acts like malloc(n)
+ *	if memory is available and otherwise does something you deem
+ *	appropriate.  If MALLOC is undefined, malloc will be invoked
+ *	directly -- and assumed always to succeed.  Similarly, if you
+ *	want something other than the system's free() to be called to
+ *	recycle memory acquired from MALLOC, #define FREE to be the
+ *	name of the alternate routine.  (FREE or free is only called in
+ *	pathological cases, e.g., in a gdtoa call after a gdtoa return in
+ *	mode 3 with thousands of digits requested.)
+ * #define Omit_Private_Memory to omit logic (added Jan. 1998) for making
+ *	memory allocations from a private pool of memory when possible.
+ *	When used, the private pool is PRIVATE_MEM bytes long:  2304 bytes,
+ *	unless #defined to be a different length.  This default length
+ *	suffices to get rid of MALLOC calls except for unusual cases,
+ *	such as decimal-to-binary conversion of a very long string of
+ *	digits.  When converting IEEE double precision values, the
+ *	longest string gdtoa can return is about 751 bytes long.  For
+ *	conversions by strtod of strings of 800 digits and all gdtoa
+ *	conversions of IEEE doubles in single-threaded executions with
+ *	8-byte pointers, PRIVATE_MEM >= 7400 appears to suffice; with
+ *	4-byte pointers, PRIVATE_MEM >= 7112 appears adequate.
+ * #define NO_INFNAN_CHECK if you do not wish to have INFNAN_CHECK
+ *	#defined automatically on IEEE systems.  On such systems,
+ *	when INFNAN_CHECK is #defined, strtod checks
+ *	for Infinity and NaN (case insensitively).
+ *	When INFNAN_CHECK is #defined and No_Hex_NaN is not #defined,
+ *	strtodg also accepts (case insensitively) strings of the form
+ *	NaN(x), where x is a string of hexadecimal digits (optionally
+ *	preceded by 0x or 0X) and spaces; if there is only one string
+ *	of hexadecimal digits, it is taken for the fraction bits of the
+ *	resulting NaN; if there are two or more strings of hexadecimal
+ *	digits, each string is assigned to the next available sequence
+ *	of 32-bit words of fractions bits (starting with the most
+ *	significant), right-aligned in each sequence.
+ *	Unless GDTOA_NON_PEDANTIC_NANCHECK is #defined, input "NaN(...)"
+ *	is consumed even when ... has the wrong form (in which case the
+ *	"(...)" is consumed but ignored).
+ * #define MULTIPLE_THREADS if the system offers preemptively scheduled
+ *	multiple threads.  In this case, you must provide (or suitably
+ *	#define) two locks, acquired by ACQUIRE_DTOA_LOCK(n) and freed
+ *	by FREE_DTOA_LOCK(n) for n = 0 or 1.  (The second lock, accessed
+ *	in pow5mult, ensures lazy evaluation of only one copy of high
+ *	powers of 5; omitting this lock would introduce a small
+ *	probability of wasting memory, but would otherwise be harmless.)
+ *	You must also invoke freedtoa(s) to free the value s returned by
+ *	dtoa.  You may do so whether or not MULTIPLE_THREADS is #defined.
+ * #define IMPRECISE_INEXACT if you do not care about the setting of
+ *	the STRTOG_Inexact bits in the special case of doing IEEE double
+ *	precision conversions (which could also be done by the strtod in
+ *	dtoa.c).
+ * #define NO_HEX_FP to disable recognition of C9x's hexadecimal
+ *	floating-point constants.
+ * #define -DNO_ERRNO to suppress setting errno (in strtod.c and
+ *	strtodg.c).
+ * #define NO_STRING_H to use private versions of memcpy.
+ *	On some K&R systems, it may also be necessary to
+ *	#define DECLARE_SIZE_T in this case.
+ * #define USE_LOCALE to use the current locale's decimal_point value.

+ *
+ * Derived from The Open Group Base Specifications Issue 7, IEEE Std 1003.1-2008
+ * as described in;
+ *   http://pubs.opengroup.org/onlinepubs/9699919799/functions/fnmatch.html
+ *
+ * Filename pattern matches defined in section 2.13, "Pattern Matching Notation"
+ * from chapter 2. "Shell Command Language"
+ *   http://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html#tag_18_13
+ * where; 1. A bracket expression starting with an unquoted <circumflex> '^' 
+ * character CONTINUES to specify a non-matching list; 2. an explicit <period> '.' 
+ * in a bracket expression matching list, e.g. "[.abc]" does NOT match a leading 
+ * <period> in a filename; 3. a <left-square-bracket> '[' which does not introduce
+ * a valid bracket expression is treated as an ordinary character; 4. a differing
+ * number of consecutive slashes within pattern and string will NOT match;
+ * 5. a trailing '\' in FNM_ESCAPE mode is treated as an ordinary '\' character.
+ *
+ * Bracket expansion defined in section 9.3.5, "RE Bracket Expression",
+ * from chapter 9, "Regular Expressions"
+ *   http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap09.html#tag_09_03_05
+ * with no support for collating symbols, equivalence class expressions or 
+ * character class expressions.  A partial range expression with a leading 
+ * hyphen following a valid range expression will match only the ordinary
+ * <hyphen> and the ending character (e.g. "[a-m-z]" will match characters 
+ * 'a' through 'm', a <hyphen> '-', or a 'z').
+ *
+ * Supports BSD extensions FNM_LEADING_DIR to match pattern to the end of one
+ * path segment of string, and FNM_CASEFOLD to ignore alpha case.
+ *
+ * NOTE: Only POSIX/C single byte locales are correctly supported at this time.
+ * Notably, non-POSIX locales with FNM_CASEFOLD produce undefined results,
+ * particularly in ranges of mixed case (e.g. "[A-z]") or spanning alpha and
+ * nonalpha characters within a range.
+ *
+ * XXX comments below indicate porting required for multi-byte character sets
+ * and non-POSIX locale collation orders; requires mbr* APIs to track shift
+ * state of pattern and string (rewinding pattern and string repeatedly).
+ *
+ * Certain parts of the code assume 0x00-0x3F are unique with any MBCS (e.g.
+ * UTF-8, SHIFT-JIS, etc).  Any implementation allowing '\' as an alternate
+ * path delimiter must be aware that 0x5C is NOT unique within SHIFT-JIS.

+/* (From RFC1521 and draft-ietf-dnssec-secext-03.txt)
+   The following encoding technique is taken from RFC 1521 by Borenstein
+   and Freed.  It is reproduced here in a slightly edited form for
+   convenience.
+
+   A 65-character subset of US-ASCII is used, enabling 6 bits to be
+   represented per printable character. (The extra 65th character, "=",
+   is used to signify a special processing function.)
+
+   The encoding process represents 24-bit groups of input bits as output
+   strings of 4 encoded characters. Proceeding from left to right, a
+   24-bit input group is formed by concatenating 3 8-bit input groups.
+   These 24 bits are then treated as 4 concatenated 6-bit groups, each
+   of which is translated into a single digit in the base64 alphabet.
+
+   Each 6-bit group is used as an index into an array of 64 printable
+   characters. The character referenced by the index is placed in the
+   output string.

+
+   Special processing is performed if fewer than 24 bits are available
+   at the end of the data being encoded.  A full encoding quantum is
+   always completed at the end of a quantity.  When fewer than 24 input
+   bits are available in an input group, zero bits are added (on the
+   right) to form an integral number of 6-bit groups.  Padding at the
+   end of the data is performed using the '=' character.
+
+   Since all base64 input is an integral number of octets, only the
+         -------------------------------------------------                       
+   following cases can arise:
+   
+       (1) the final quantum of encoding input is an integral
+           multiple of 24 bits; here, the final unit of encoded
+	   output will be an integral multiple of 4 characters
+	   with no "=" padding,
+       (2) the final quantum of encoding input is exactly 8 bits;
+           here, the final unit of encoded output will be two
+	   characters followed by two "=" padding characters, or
+       (3) the final quantum of encoding input is exactly 16 bits;
+           here, the final unit of encoded output will be three
+	   characters followed by one "=" padding character.
