changegroup: introduce cg3, which has support for exchanging treemanifests

I'm not entirely happy with using a trailing / on a "file" entry for
transferring a treemanifest. We've discussed putting some flags on
each file header[0], but I'm unconvinced that's actually any better:
if we were going to add another feature to the cg format we'd still be
doing a version bump anyway to cg4, so I'm inclined to not spend time
coming up with a more sophisticated format until we actually know what
the next feature we want to stuff in a changegroup will be.

Test changes outside test-treemanifest.t are only due to the new CG3
bundlecap showing up in the wire protocol.

Many thanks to [e-mail] and [e-mail] for helping
me with various odd corners of the changegroup and treemanifest API.

0: It's not hard refactoring, nor is it a lot of work. I'm just
disinclined to do speculative work when it's not clear what the
customer would actually be.
