Don't touch ref files manually

Messing with files manually doesn't work if the refs are packed. The
officially preferred way is to use git-update-ref, git-show-ref,
et.al. So do that.

As a consequence of this, we have some small behavior changes:

  * We used to not leave empty directories behind in the refs tree.
    But now that's all in the hands of git-update-ref, which does
    leave them behind. Tests that assumed the old behavior have been
    fixed.

  * We (that is, git-show-ref) no longer distinguish between a ref
    that doesn't exist and a ref that contains garbage. So the tests
    that assumed we'd fail when encountering a spurious ref with
    garbage in it have had to go through attitude readjustment.
