update-ref and tag: add --create-reflog arg
Allow the creation of a ref (e.g. stash) with a reflog already in
place. For most refs (e.g. those under refs/heads), this happens
automatically, but for others, we need this option.
Currently, git does this by pre-creating the reflog, but alternate ref
backends might store reflogs somewhere other than .git/logs. Code
that now directly manipulates .git/logs should instead use git
plumbing commands.
I also added --create-reflog to git tag, just for completeness.
In a moment, we will use this argument to make git stash work with
alternate ref backends.
