These should probably have been cleaned up in each commit to allow
cherry-picking, but due to time I haven't been able to.
- Went with creating an mdir copy in lfs_dir_commit. This handles a
number of related cleanup issues in lfs_dir_compact and it does so

in the mlist.
- Eliminated code left by the ENOSPC file outlining
- Cleaned up TODOs and lingering comments
- Changed the reentrant many directory create/rename/remove test to use
a smaller set of directories because of space issues when
