[svn-r24993] Purpose:
Adds write tracking to the core VFD, which can be configured
via the H5Pset/get_core_write_tracking() API call. When enabled
and writing to the backing store is enabled, this feature will
track writes and only write out the changed bytes on flush/close.
Tested on:
32-bit LE linux (jam) w/ Fortran and C++
64-bit BE linux (ostrich)
64-bit Darwin 12.5.0 (kite)
All were tested using the core VFD w/ paging on (core_paged
in the VFD list). Make check-vfd was also tested on jam.
