Michael Haggerty 49aebcf432 packed_refs_unlock(), packed_refs_is_locked(): new functions
Add two new public functions, `packed_refs_unlock()` and
`packed_refs_is_locked()`, with which callers can manage and query the
`packed-refs` lock externally.

Call `packed_refs_unlock()` from `commit_packed_refs()` and
`rollback_packed_refs()`.
