- Prevented removing and renaming of the root directory. This is done by
repurposing the INVAL error in lfsr_mtree_lookup to indicate the
found entry is the root.
The root entry has special behavior in almost every function, owing to
the fact it doesn't really have an mid/rid. So I think this is a
reasonable approach.
- Added support for lfsr_stat of the root directory.
- Fixed off-by-two in lfsr_dir_seek thanks to the "." and ".." entries.
Humorously there is a comment noting this but the code didn't
actually match the comment.
