Adopted buffer followed by size. The other order was original
chosen due to some other functions with a more complicated
parameter list.
This convention is important, as the bd api is one of the main
apis facing porting efforts.
After quite a bit of prototyping, settled on the following functions:
- lfs_dir_alloc - create a new dir
- lfs_dir_fetch - load and check a dir pair from disk
- lfs_dir_commit - save a dir pair to disk
- lfs_dir_shift - shrink a dir pair to disk
- lfs_dir_append - add a dir entry, creating dirs if needed
- lfs_dir_remove - remove a dir entry, dropping dirs if needed
Additionally, followed through with a few other tweaks
