I hooked the refreshing into get_packed_refs, since then all callers get
it for free. It makes me a little nervous, though, just in case some
caller really cares about calling get_packed_refs but not having the
list of packed-refs change during the call. peel_ref looks like such a
function, but isn't, for reasons I'll explain in a followup patch.

I thought I would need the cleanups below for peel_ref, but it turns out
that the middle chunk of the function is never exercised. They conflict
textually with Michael's mh/packed-refs-various topic, so I think it may
make sense to just rebase them on top of that.

  [1/2]: peel_ref: rename "sha1" argument to "peeled"
  [2/2]: peel_ref: refactor for safety with simultaneous update
