Renamed traversal -> trv

Browse Source 
- test_traversal -> test_trvs
- lfs3_traversal_t -> lfs3_trv_t
- lfs3_btraversal_t -> lfs3_btrv_t
- t -> trv
- bt -> btrv
- lfs3_traversal_* -> lfs3_trv_*
- lfs3_btraversal_* -> lfs3_btrv_*

The traversal type is becoming one of the more fundamental types in
littlefs, and if DIR and REG both get shortened names, it makes sense
for TRV to have one as well.

This also removes the temptation to use t for traversals, which is
probably an even worse name.

---

Note that lfs3_btree_traverse, lfs3_mtree_traverse, etc, remain
unaffected. This may change in the future, but it's interesting to note
that verbs seem to need much less typing than nouns.
