SilcStack Interface Header: silcstack.h DESCRIPTION
     Implementation of data stack which can be used to allocate memory from
     the stack.  Basicly SilcStack is a pre-allocated memory pool system
     which allows fast memory allocation for routines and applications that
     frequently allocate small amounts of memory.  Other advantage of this
     system is that there are no memory leaks, as long as the stack is
     freed eventually.  Since the stack is usually allocated only once this
     is not an issue.

     SilcStack can be used to allocate both aligned and unaligned memory so
     it is suitable for allocating structures and is optimal for allocating
     strings and data buffers.  SilcStack also supports stack pushing and
     popping allowing to push the stack, allocate memory and then pop it
     to free the allocated memory.  The freeing does not actually do any
     real memory freeing so it is optimized for performance.

     A basic set of utility functions are provided for application that wish
     to use the SilcStack as their primary memory allocation source.  The
     following functions support SilcStack:

     silc_smalloc, silc_smalloc_ua, silc_scalloc, silc_srealloc, silc_smemdup,
     silc_sstrdup, silc_buffer_salloc, silc_buffer_salloc_size,
     silc_buffer_srealloc, silc_buffer_srealloc_size, silc_buffer_scopy,
     silc_buffer_sclone, silc_buffer_sformat, silc_buffer_sformat_vp,
     silc_buffer_sstrformat, silc_buffer_senlarge, silc_mp_sinit

     The data stack is not thread-safe.  If the same stack context must be
     used in multithreaded environment concurrency control must be employed.
     Each thread should allocate their own SilcStack.
