runtimes/google/ipc: rework 'hybrid' websocket protocol support.

- introduce a new protocol type, wsh, which can listen for both
  tcp and websocket connections.
- modify vc's to ensure that they use a control byte that can't
  be confused with websockets. Roll is straightforward, push to
  servers first, update clients, remove old support
