Convert some H5MM calls to standard C equivalents (#2382)

* H5MM_calloc and malloc are now mapped to stdlib C calls
* H5MM_memcpy now maps directly to memcpy in release builds
* H5MM_memcpy is still implemented as a separate function that
   checks for buffer overlap when H5MM_DEBUG is defined
   (default w/ debug builds)
* Switches many library memcpy calls to use H5MM_memcpy
* Fixes a possible zero allocation in H5Olayout.c
