wireproto: only expose "getbundle" and "unbundle" to v1 transports These are the most complicated wire protocol commands. I don't want to deal with porting them just yet. Let's disable both of them on version 2 transports so we drive the final wedge between command handlers and start to evolve version 2 command handlers more.
