This patch declares and implements two functions:
1. for_each_note_ref() - for iterating over note references in refs/notes.
This is analogous to for_each_tag_ref(), for_each_branch_ref() and
for_each_remote_ref(), which is already present.
2. cleanup_notes_subdirs() - a convenience function for removing empty
subdirectories from refs/notes. These subdirectories would otherwise be
left behind after removing notes, or after packing note refs.
The above functions will be used by subsequent git-note patches.
