We were sending a channeld message to onchaind, which was v. confusing
due to overlap. We make all the numbers distinct, which means we can
also add an assert() that it's valid for that daemon, which catches
such errors immediately.

This change is really to allow us to have a --dev-fail-on-subdaemon-fail option
so we can handle failures from subdaemons generically.
It also neatens handling so we can have an explicit callback for "peer
did something wrong" (which matters if we want to close the channel in
that case).

And store in peer->last_tx/peer->last_sig like all other places,
that way we broadcast it if we need to.
Note: the removal of tmpctx in funder_channel() is needed because we
use txs[0], which was allocated off tmpctx.

The format we use to generate marshal/unmarshal code is from
the spec's tools/extract-formats.py which includes the offset:
we don't use it at all, so rather than having manually-calculated
(and thus probably wrong) values, or 0, emit it altogther.

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.

Simplifies state machine. Master still has to calculate the tx to get
the signature and broadcast, but now the opening daemon funding path
is a simple request/response.

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.

We use the fourth value (size) to determine the type, unless the fifth
value is suppled. That's silly: allow the fourth value to be a typename,
since that's the only reason we care about the size at all!
Unfortunately there are places in the spec where we use a raw fieldname
without '*1' for a length, so we have to distingish this from the
typename case.
