Renamed omdir -> handle

Browse Source 
- lfs3_omdir_t -> lfs3_handle_t
- lfs3.omdirs -> lfs3.handles
- o -> h
- lfs3_omdir_* -> lfs3_handle_*
- lfs3_omdir_ismidopen -> lfs3_mid_isopen

From conversations with users, the term "handle" or "file handle" seems
to be the most common/easily understood term for the lfs3_file_t struct
itself. It makes sense to adopt this in our codebase.

I usually dislike inventing new names for things when prefixes can imply
a relationship (size -> ssize, cache -> rcache, shrub -> bshrub, etc),
but lfs3_omdirs_t was probably a bit much.
