- test_dtree - Pure directory creation/deletion/move functionality
testing. This ends up testing the core of littlefs file entry
manipulation, since directories is all we need for that.
- test_dseek - Tests more of the corner cases specific to directory
iteration and seeking. This involves an annoying amount of
interactions with concurrent updates to the filesystem that are
complicated to test for.
Also generally renaming the "fstree" concept to "dtree". This only
changes dbglfs.py as far as I'm aware. It's useful to have a name for
this thing and "directory tree" fits a bit better than "filesystem tree"
which could be ambiguous when we also have the "metadata tree" as a
different concept.
