We have some duplication in handling queues, so this is an attempt at deduplicating some of that work. `daemon_conn` now uses the `msg_queue` and `channeld` was also migrated to `msg_queue`. At the same time I made `msg_queue` create a copy of the messages or takes over messages marked with `take()`. This should make cleaning up messages easier.
