repository: introduce register_changeset callback

The new callback is called whenever a changeset is added to the repository
(commit, unbundle or exchange). Since the bulk operations already parse
the changeset (readfiles or full changesetrevision), always use the
latter to avoid redundant lookups. The first consumer of the new
interface needs to look at extra.
