Fixed/implemented renaming open files

Browse Source 
This requires two things:

1. Any opened file handles need to have their mid/mdir updated after the
   rename succeeds.

2. Any shrubs/sprouts need to be copied over to the new mdir, even if
   they aren't in-tree.

The LFSR_TAG_MOVE operation is starting to look an awfully lot like
lfsr_mdir_compact... Unfortunately lfsr_mdir_compact, uh, compacts,
whereas LFSR_TAG_MOVE appends to the rbyd like normal, so it's not clear
exactly _how_ to deduplicate.
