/**
 *    @file
 *      This file implements memory management functions for the Weave Security Manager.
 *      The implementation is based on the C Standard Library malloc() and free() functions.
 *      This implementation is used when #WEAVE_CONFIG_SECURITY_MGR_MEMORY_MGMT_MALLOC
 *      is enabled (1).
 *
 *    @note This implementation ignores some of the function's input parameters,
 *      which were intended to help with better memory utilization. The assumption
 *      is that platforms that choose this implementation are not memory constrained.
