bundle2: allow bundle2 for pulling over the wire This changeset makes `wireprotocol` peers advertise bundle2 capability and comply with bundle2 `getbundle` requests. Note that advertising bundle2 could make a client try to use it for push. Such pushes would fail. However, I do not expect any human being to have enabled bundle2 on their server yet.
