[svn-r10750] Purpose:

    New feature.

Description:
    Add "memory pool" internal data structure.  This set of routines is
designed to add a way to allocate small pieces of information for a particular
purpose and then free all the pieces at once (i.e. without having to free each
piece individually).  Memory pools are also good for localizing lots of small
allocations that logically belong together.

    For example, if you were constructing a temporary linked list, you could
create a new memory pool, allocate all the nodes for the list from the memory
pool and when you were done with the list, just destroy the pool instead of
tracking through the list and freeing each block independently.

Platforms tested:
    FreeBSD 4.11 (sleipnir)
    h5committest
