The new flag loosens the usual "self containedness" requirment of packfiles, and sends deltified representation of objects when we know the other side has the base objects needed to unpack them. This would help reducing the transfer size.

* Together with the other two patches, this allows you to say "git-send-pack --thin" to implement the "delta transfer" we discussed earlier.
