[PATCH] refs.c: rework ref_locks by abstracting from underlying struct lock_file
Instead of calling close_lock_file() and commit_lock_file() directly,
which take a struct lock_file argument, add two new functions:
close_ref() and commit_ref(), which handle calling the previous
lock_file functions and modifying the ref_lock structure.
