Rusty Russell 996567c250 lightningd: update BOLT to add channel_reestablish message.
We don't handle it yet though.

Rusty Russell f7a22b699e lightningd/peer_control: embed id, don't use pointer.
We always know it now we have struct connection, so we don't need a pointer.

Rusty Russell ed16bb3134 channeld: send optional init message.
We use this to make it send the funding_signed message, rather than having
the master daemon do it (which was even more hacky).  It also means it
can handle the crypto, so no need for the packet to be handed up encrypted,
and also make --dev-disconnect "just work" for this packet.

Rusty Russell 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.

Rusty Russell 1e36a19164 lightningd/peer_control: keep cryptostate.
Like the fd, it's only useful when the peer is not in a daemon, so we
free & NULL it when that happens.

Rusty Russell 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.

Rusty Russell 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.

Rusty Russell ba12e316f1 lightningd: fix minimum depth.
Only the side *accepting* the connection gives a `minumum_depth`, but both
sides are supposed to wait that long:

BOLT #2:

	### The `funding_locked` message
...
	#### Requirements
	
	The sender MUST wait until the funding transaction has reached
	`minimum-depth` before sending this message.

Rusty Russell 85fd8218e2 lightningd: track channel balance.
This is an approximate result (it's only our confirmed balance, not showing
outstanding HTLCs), but it gives an easy way to check HTLCs have been
resolved.

Rusty Russell 38bffc0f0c lightningd/subd: support multiple fds sent at once in request reply.
Instead of indicating where to place the fd, you say how many: the
fd array gets passed into the callback.

This is also clearer for the users.

Rusty Russell 1800e84db7 subdaemon: callback to handle subdaemon status updates.
It's a bit messy, since some status messages are accompanied by an FD:
in this case, the handler returns STATUS_NEED_FD and we read that then
re-call the handler.
