We have a race where we start onchaind, but state is unchanged, so checks
like peer_control.c's:
peer_ready = (peer->owner && peer->state == CHANNELD_AWAITING_LOCKIN);
if (!peer_ready) {
log_unusual(peer->log,
"Funding tx confirmed, but peer state %s %s",
peer_state_name(peer->state),
peer->owner ? peer->owner->name : "unowned");
} else {
subd_send_msg(peer->owner,
take(towire_channel_funding_locked(peer,
peer->scid)));
}
Can send to the wrong daemon.

This is a transitional state, while we're waiting to see the
closing tx onchain (which is To Be Implemented).
The simplest way to do re-transmission is to re-use closingd, and just
disallow any updates.

We keep the scriptpubkey to send until after a commitment_signed (or,
in the corner case, if there's no pending commitment). When we
receive a shutdown from the peer, we pass it up to the master.
It's up to the master not to add any more HTLCs, which works because
we move from CHANNELD_NORMAL to CHANNELD_SHUTTING_DOWN.

This means there's no GETTING_HSMFD state at all any more. We
temporarily play games with the hsm fd; those will go away once we're
done.

Instead, send it the funding_signed message; it can watch, save to
database, and send it.
Now the openingd fundee path is a simple request and response, too.

1. We explicitly assert what state we're coming from, to make transitions
clearer.
2. Every transition has a state, even between owners while waiting for HSM.
3. Explictly step though getting the HSM signature on the funding tx
before starting channeld, rather than doing it in parallel: makes
states clearer.

We currently create a peer struct, then complete handshake to find out
who it is. This means we have a half-formed peer, and worse: if it's
a reconnect we get two peers the same.
Add an explicit 'struct connection' for the handshake phase, and
construct a 'struct peer' once that's done.
