d04b7af56e onchain: add initial onchain state.
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.

87232ec25c lightningd: new peer state CLOSINGD_COMPLETE.
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.

866ac79850 channeld: shutdown support.
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.

232a182b25 lightningd: get fd from HSM synchronously.
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.

43ec37b865 openingd: fundee: don't send watch command to master.
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.

780b3870ad lightningd: peer state cleanup.
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.

f6495d3310 lightningd/peer_control: don't create peer struct until we've connected.
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.

34e6e56471 lightningd: introduce peer_state enum.
The actual state names are place holders for now, really.
