 * Open a new database using the softoken. The caller is responsible for making

 * new database per call if the caller wants to get meaningful information
 * about the new database.
 *
 * moduleSpec is the same data that you would pass to softoken at
 * initialization time under the 'tokens' options. For example, if you were
 * to specify tokens=<0x4=[configdir='./mybackup' tokenDescription='Backup']>
 * You would specify "configdir='./mybackup' tokenDescription='Backup'" as your
 * module spec here. The slot ID will be calculated for you by
 * SECMOD_OpenUserDB().
 *
 * Typical parameters here are configdir, tokenDescription and flags.
 *
 * a Full list is below:
 *
 *
 *  configDir - The location of the databases for this token. If configDir is
 *         not specified, and noCertDB and noKeyDB is not specified, the load
 *         will fail.
 *   certPrefix - Cert prefix for this token.
 *   keyPrefix - Prefix for the key database for this token. (if not specified,
 *         certPrefix will be used).
 *   tokenDescription - The label value for this token returned in the
 *         CK_TOKEN_INFO structure with an internationalize string (UTF8).
 *         This value will be truncated at 32 bytes (no NULL, partial UTF8
 *         characters dropped). You should specify a user friendly name here
 *         as this is the value the token will be referred to in most
 *         application UI's. You should make sure tokenDescription is unique.
 *   slotDescription - The slotDescription value for this token returned
 *         in the CK_SLOT_INFO structure with an internationalize string
 *         (UTF8). This value will be truncated at 64 bytes (no NULL, partial
 *         UTF8 characters dropped). This name will not change after the
 *         database is closed. It should have some number to make this unique.
 *   minPWLen - minimum password length for this token.
 *   flags - comma separated list of flag values, parsed case-insensitive.
 *         Valid flags are:
 *              readOnly - Databases should be opened read only.
 *              noCertDB - Don't try to open a certificate database.
 *              noKeyDB - Don't try to open a key database.
 *              forceOpen - Don't fail to initialize the token if the
 *                databases could not be opened.
 *              passwordRequired - zero length passwords are not acceptable
 *                (valid only if there is a keyDB).
 *              optimizeSpace - allocate smaller hash tables and lock tables.
 *                When this flag is not specified, Softoken will allocate
 *                large tables to prevent lock contention.
