teach update-ref a "--rename" option

You can rename a branch with "branch -m", but there is no
plumbing mechanism to rename an arbitrary ref. You can
simulate it with:

  git update-ref newname oldname &&
  git update-ref -d oldname

but that drops the reflog from oldname. This patch instead
allows:

  git update-ref --rename oldname newname

Unlike "git branch -m", it does not munge the branch config
(since this plumbing command is purely about refs), nor does
it allow a missing "oldname" to mean an implicit HEAD
(because it is plumbing, and we are better to make the
caller be explicit than risk a surprise).
