It has only one vestigial use for cancel requests that we can get rid of.  Since a cancel request is indicated by a special protocol version number, we can use the ProtocolVersion type, which MsgType was based on.  (If this is also found confusing, we could also use uint32 directly.)

LGTM. I searched over the source tree, MsgType had only a single usage before the patch, so it makes sense to remove it.
