Merge remote-tracking branch 'origin/selection_io' into selection_io_with_subfiling_vfd
and resolved conflicts. Note that H5S_get_validated_dataspace() in H5S.c was removed. Re-inserted this function for now. Update testpar/t_subfiling_vfd.c to set HD_enable_selection_io_g. Uses MPI flag on the sub-filing VFD is still not set, as the VFD seg faults if it is. Tested parallel / debug on Charis and Jelly.
