[svn-r28777] Description:

    Add --enable-memory-alloc-sanity-check option to configure, to track and
sanity check memory allocations within the library.  This is orthogonal to the
--enable-using-memchecker option and can be used with/without it.

Tested on:
    MacOSX/64 10.11.2 (amazon) w/serial & parallel
    (h5committest forthcoming)
