normalize_name: allow more references under refs/

Browse Source 
Allow any well-formed reference name to live under refs/ removing the
condition that they be under refs/{heads,tags,remotes}/ as was the
design of git.

An exception is made for HEAD which is allowed to contain an OID
reference in detached HEAD state.
