Merge branch 'jh/libify-note-handling'
Make it possible to call into copy-notes API from the sequencer code. * jh/libify-note-handling: Move create_notes_commit() from notes-merge.c into notes-utils.c Move copy_note_for_rewrite + friends from builtin/notes.c to notes-utils.c finish_copy_notes_for_rewrite(): Let caller provide commit message
