Why?
- lfsr_mtree_lookupleaf vs lfsr_mtree_commit is inconsistent. Should
lfsr_mdir_commit be called lfsr_mtree_commitleaf? That'd be weird.
It's reasonable to call mdirs entries of the mtree, but it'd be weird
to call rbyds entries of btrees, so the inconsistency there is
expected.
- lfsr_mtree_lookup/lfsr_mtree_lookupnext (going mtree -> mdir) aren't
actually useful.
- The lfsr_mtree_namelookup/lfsr_mtree_namelookupleaf split is just more
of a headache than it's worth.
