More fixes to get the basic end-to-end delivery mechanisms working.

- Lots of Pipermail work just to get it to play nice with the new apis.
- Fix ARCHIVE_SCRUBBER
- Lots of changes to mailman.app.archiving, especially to provide an
  adapter from the new MailingList api to the one expected by
  Pipermail (e.g. archive_dir()).
- Add a test of the basic pipermail archiver.
