[PATCH] Finish initial cut of git-pack-object/git-unpack-object pair.
This finishes the initial round of git-pack-object / git-unpack-object pair. They are now good enough to be used as a transport medium: - Fix delta direction in pack-objects; the original was computing delta to create the base object from the object to be squashed, which was quite unfriendly for unpacker ;-). - Add a script to test the very basics. - Implement unpacker for both regular and deltified objects.
