send-pack: cluster ref status reporting

Instead of intermingling success and failure, we now print:

  1. all uptodate refs (if args.verbose is enabled)
  2. successfully pushed refs
  3. failed refs

with the assumption that the user is most likely to see the
ones at the end, and therefore we order them from "least
interesting" to "most interesting."
