channel/msgpack_rpc: Refactor msgpack_rpc_notification/serialize_event

- Generalize some argument names(event type -> event name,
                                 event data -> event arg)
- Rename serialize_event to serialize_message
- Rename msgpack_rpc_notification to msgpack_rpc_message
- Extract the message type out of msgpack_rpc_message
- Add 'id' parameter to msgpack_rpc_message/serialize_message to create messages
  that are not notifications
