Implement new transaction model, transactions are now hidden from the
API, H5TR functions have no effect. Added support for H5Fflush. Added H5VLdaosm_snap_create and
H5Pset_daosm_snap_open to save and load snapshots. Added enforcement of
file access flags. Updated examples. Other minor fixes/cleanup.
