  Branch: 7.9

program_path_to_name() now knows about compat modules.
compat_handler_cache is no longer a weak mapping, since it is wasteful to gc the compat handlers.
compat_handler_cache now also contains the handler for the currentversion.
currentversion is now generated from __REAL_{MAJ,MIN}OR__ for clearity.
