[svn-r25033] Purpose:
Merged r24993 from the trunk.
Adds core VFD write tracking functionality. When enabled, the core VFD
will track dirty regions of the file and only write out the changed
regions. The new H5Pget/set_core_write_tracking() API call controls this
feature. A new "core_paged" VFD target was added to the check-vfd target
in test/Makefile.am that runs all tests with the new write tracking
functionality.
Tested on:
32-bit LE linux (jam)
64-bit LE linux (koala)
64-bit BE linux (ostrich)
Each platform was tested with HDF5_DRIVER set to "core" and "core_paged".
Jam was also tested with the standard sec2 driver.
