This was a pretty simple oversight on my part. Conceptually, there's no
difference between lfs_fs_getattr and lfs_getattr("/"). Any operations
on directories can be applied "globally" by referring to the root
directory.
Implementation wise, this actually fixes the "corner case" of storing
attributes on the root directory, which is broken since the root
directory doesn't have a related entry. Instead we need to use the root
superblock for this purpose.
Fewer functions means less code to document and maintain, so this is a
nice benefit. Now we just have a single lfs_getattr/setattr/removeattr set
of functions along with the ability to access attributes atomically in
lfs_file_opencfg.
