The interfaces defined in the `ref_storage_be` are carefully structured in semantic. It's organized as the five parts: 1. The name and the initialization interfaces. 2. The ref transaction interfaces. 3. The ref internal interfaces (pack, rename and copy). 4. The ref filesystem interfaces. 5. The reflog related interfaces. To keep consistent with the git-fsck(1), add a new interface named "fsck_refs_fn" to the end of "ref_storage_be". This semantic cannot be grouped into any above five categories. Explicitly add blank line to make it different from others.
