P2P protocol version 2, adding SUCCESS-PLUS and ALREADY-HAVE-PLUS
Client side support for SUCCESS-PLUS and ALREADY-HAVE-PLUS is complete, when a PUT stores to additional repositories than the expected on, the location log is updated with the additional UUIDs that contain the content. Started implementing PUT fanout to multiple remotes for clusters. It is untested, and I fear fencepost errors in the relative offset calculations. And it is missing proxying for the protocol after DATA.
