Do ref matching on the sender side rather than on receiver
This makes the receiver always send a full list of valid refs, which will allow us to do better packs, as well as handle creation of new refs. Eventually. Right now we just moved the matching and enabled it. So now you can do git-send-pack host:path branch1 branch2 to only send branches "branch1" and "branch2".
