largefiles status: update lfdirstate with result from cleanliness check
Problem: 'hg status' kept checking largefiles with an unknown state until some
other command wrote the updated dirstate.
Solution: Add missing lfdirstate.write().
"""Extension to verify locks are obtained in the required places.
This works by wrapping functions that should be surrounded by a lock
and asserting the lock is held. Missing locks are called out with a
traceback printed to stderr.
This currently only checks store locks, not working copy locks.
