tag: add repository argument to deref_tag

Add a repository argument to allow the callers of deref_tag to be more specific about which repository to act on. This is a small mechanical change; it doesn't change the implementation to handle repositories other than the_repository yet. As with the previous commits, use a macro to catch callers passing a repository other than the_repository at compile time.
