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:

Maintaining it was always fraught, since the command could go away
if the JSON RPC died. Most recently, it was broken again on shutdown
(see below).
In future we may allow pay commands to block on previous payments, so
it won't even be a 1:1 mapping. Generalize it: keep commands in a
simple list and do a lookup when a payment fails/succeeds.

This is a transitional patch so we can still close channels cleanly;
for want of a better option, I hooked it into --deprecated-apis.

We shouldn't fail negotiation just because they exceeded what we thought
fair: we're better off as long as it's actually <= final commitment fee.

We move it into jsonrpc where it belongs, and make it fail the command.
This means it can tell us exactly what was wrong.

With the new 'human-readable' mode of lightning-cli, this actually produces
a valid config file. It's a bit hacky though...
