We can be spammy, which is good for tests, but bad for our simple message queue.
This avoids breaking our tests but also avoid the worst case (1M entries and counting!)
for gossip status messages in the case where we're syncing a large peer.

We had at least one bug caused by it not returning true when it had
queued something. Instead, just re-check thq queue after it's called.

This way there's no need for a context pointer, and freeing a msg_queue
frees its contents, as expected.

It means an extra allocation at startup, but it means we can hide the definition,
and use standard patterns (new_daemon_conn and typesafe callbacks).

Now it just returns true if it queued something. This allows it
to queue multiple packets, and lets it share code paths with other code
in future patches.
