- Refactor the way databases are schema-migrated so that load_migrations()

   can be tested separately.
 - Add an `until` argument to load_migrations() so that we can load only up to
   a given timestamp.
 - In load_migrations(), ignore files in which the `version` part of the file
   name is empty.
 - In migrations.rst, use the new, better way of ensuring post-test cleanup.
 - Add tests for partial upgrades.
 - LP: #971013 - schema migrations for beta 2.
 - LP: #967238 - IMailingList.archive + IMailingList.archive_private ->
   IMailingList.archive_policy, and add ArchivePolicy enum.
 - Move the `chdir` context manager to helpers.py and add `temporary_db`
   context manager.
