This makes mtree implicit in most of littlefs's core functions, which
simplifies things. It also makes lfsr_mtree_traverse naming consistent
with other mtree-esque operation.
Renames:
- Renamed lfsr_fs_weight -> lfsr_mtree_weight (implicit mtree)
- Renamed lfsr_mtree_weight -> lfsr_mtree_weight_ (explicit mtree)
- Renamed lfsr_fs_traverse* -> lfsr_mtree_traverse*
- Renamed LFSR_TSTATE_* -> LFSR_MTRAVERSAL_*
Implicit mtree functions, note these are pretty much the backbone of
littlefs:
- lfsr_mtree_weight
- lfsr_mtree_lookup
- lfsr_mtree_seek
- lfsr_mtree_namelookup
- lfsr_mtree_pathlookup
- lfsr_mtree_traverse
This makes the naming is a bit inconsistent with lfsr_btree_*,
lfsr_rbyd_*, etc, but sometimes rules needs to bend a bit.
Besides, most of these functions needed access to the mroot anyways, so
it's not like they were really ever able to operate on independent
mtrees correctly.
And you can't complain about the code savings:
code stack
before: 34562 2624
after: 34426 (-0.4%) 2624 (+0.0%)
