Log Message:
pluck a number of fixes from mainline mtn to fix a bug introduced shortly
before the 0.35 release, which could cause monotone db files to grow
larger than necessary by not removing some file/delta content as they were
superceded by new versions.  Most noticable on fresh pulls, or
via "db check".  Extra content can be cleaned up with a local
sync into a fresh db.
