This came up while debugging the gossip daemon breaking upon calling
`getroute`. It turns out that log was still writing to stdout, but
stdout had been reused for an inter-daemon socket, which would
break...
We remove the unused status_send_fd, and rename status_send_sync (it
should only be used for that case now).
We add a status_setup_async(), and wire things internally to use that
if it's set up: status_setup() is renamed status_setup_sync().

The gossip subdaemon previously passed the fd after init: this is
unnecessary for peers which simply want to gossip (and not establish
channels).
Now we hand the gossip fd back with the peer fd. This adds another
error message for when we fail to create the gossip fds.

This measn that gossip (which also wants to wake it) needs to wake
the queue, not the daemon_conn.

We were firing off the wakeup timers all over the place, out of fear
that we would be triggering two concurrent broadcasts. This is not
really the case since the wakeup calls are idempotent. This also
allows us not to differentiate between triggering a broadcast on a
local peer or on a proxied peer.
This includes some code duplication, but since the two write targets
are fundamentally different we might need to refactor a bit more to
unify them again.
We will eventually ween off of the logging, or replace it with status
messages that log in `lightningd`, but for now we still have the
routing module that does some logging.
Or for blackbox tests --gdb1=<subdaemon> / --gdb2=<subdaemon>.
This makes the subdaemon wait as soon as it's execed, so we can attach
the debugger.

Raw crypto_state is what we send across the wire: the peer one is for
use in async crypto io routines (peer_read_message/peer_write_message).

The peer is woken up every 30 seconds to deliver the backlog of
messages. Additionally I added the normal message queue to be able to
send non-gossip message to the peer.
It's awkward to handle them differently. But this change means we
need to expose them to the generated code.
