This is not connected yet; during the transition, there will be a 1:1
mapping from channel to peer, so we can use channel2peer and peer2channel
to shim between them.

Both when we forget about an opening peer, and at startup. We're
going to be relying on this, and the next patch, as we refactor
peer/channel handling to mirror the db.

Combining the two was just awkward, so it's clearer to have separate
functions. And we make the lower-level functions do the escaping.

The JSON-RPC spec specifies that if the request is unparseable we
should return an error with a NULL id. This is a bit more friendly
than slamming the door in the face.

As reported by @practicalswift in #945 it is possible to inject
non-printable, or shell escape, characters in a json command, that
will fail to parse and then clear the shell.

Now we have wirestring, this is much more natural. And with the
24M length limit, we needn't be so concerned about dumping 64k peer
messages in hex.

These are now logically arrays of pointers. This is much more natural,
and gets rid of the horrible utxo array converters.

`activate_peer` does little more than wiring up some txwatches and
asking `gossipd` to reconnect to the peer. If the peer manages to
reconnect before we activate then we would crash.
This just changes the `assert` causing the crash into a conditional
whether we need to reconnect or not.

Due to the broadcast failure quite a few users are reporting channels
stuck in awaiting lockin. This commit adds a `dev-forget-channel`
command that checks whether the funding outpoint is in the UTXO, and
forgets the channel if not. The UTXO check can be overridden with the
`force` parameter, but that is dangerous.

We were sideloading it, which is awkward, now it's a field that we can
actually use in the code.

We currently don't handle LOG_IO properly, and we turn it into a string
before handing it to the ->print function, which makes it ugly for
the case where we're using copy_to_parent_log, and also means in
that case we lose *what peer* the IO is coming from.
Now, we handle the io as a separate arg, which is much neater.

Logging often gets called in error paths, so this is just good hygiene.
Also, log_io does this already.

libunwind does not accept a NULL parameter for the error callback. It
will simply call into the NULL pointer. So add an error callback.
This makes the crash output somewhat more sensible on FreeBSD, where
there is no libunwind stack trace available:
