[svn-r20658] Description:
Bring code contribution from John Biddiscombe into trunk, according to
IP assignment #002 (on file). Checkin message from John is:
This patch includes the changes necessary to compile a Virtual File
Driver outside of the main hdf5 build and still have it link against
the hdf5 core and work correctly at run-time.
Certain MPI-IO related VFD checks were hard-coded in the hdf5 source
and so it was not possible to extend the functionality to new drivers.
Removed IS_H5FD_MPI macros and replaced with H5F_HAS_FEATURE calls with
new keys, H5FD_FEAT_HAS_MPI and H5FD_FEAT_ALLOCATE_EARLY.
Change H5FD cleanup (term_interface) so that file drivers call
terminate when their class types are deleted instead of explicitly
being called from the finalization code. Move the terminate call out
of H5I and put it into the FD class_free call. Remove the now obsolete
check of handles after cleaning types at termination time.
