changegroup: emit revisiondelta instances from deltagroup()

By abstracting the concept of a delta group away from its
serialization (the changegroup format), we make it easier
to establish alternate serialization formats. We also make
it possible to move aspects of delta group generation into
the storage layer. This will allow storage to make decisions
about e.g. delta parent choices without the changegroup code
needing storage APIs to determine delta parents. We're still
a bit of a way from there. Future commits will work towards
that world.
