daemon: exit main loop to free dead peers.
When a peer is finally to be freed (ie. STATE_CLOSED), doing this
inside the state logic is a bit fraught. We're better off exiting the
io loop and freeing it there.

8b666ea449
daemon: queue commands rather than executing them immediately.
When the only commands are via JSON, you might argue that we should
simply insist the user not operate on the same peer in parallel. That
would suck, and also we need to handle the case of a command from
a timer (eg. HTLC expiry!) or a bitcoin event.
So, we need a queue for commands, but also we need to do some of the
command checking just before the command runs: the HTLC we're dealing
with might have vanished for example.
The current command is wrapped in an anonymous "curr_cmd" struct
for extra clarity.
