We currently provide the functionality to iterate over refs and call a
specific callback. This functionality currently supports iterating over
the entire "refs/*" space or directly the "HEAD" ref. This leaves
operational refs "ORIG_HEAD", "REBASE_HEAD" and so forth behind.
In the following commit, we introduce a mechanism to process all the
operational refs outside the "refs/*" space. To do this, we require a
function similar `refs_head_ref`, which can process a single specified
reference. This commit introduces `refs_single_ref` to fill in that gap.
