Make walker.fetch_ref() take a struct ref.
This simplifies a few things, makes a few things slightly more complicated, but, more importantly, allows that, when struct ref can represent a symref, http_fetch_ref() can return one. Incidentally makes the string that http_fetch_ref() gets include "refs/" (if appropriate), because that's how the name field of struct ref works. As far as I can tell, the usage in walker:interpret_target() wouldn't have worked previously, if it ever would have been used, which it wouldn't (since the fetch process uses the hash instead of the name of the ref there).
