A convenient alias for char *, though we don't allow control characters
so our logs can't be fooled with embedded \n.

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

```

E AssertionError: assert [True, False] == [True, True]
E At index 1 diff: False != True
E Full diff:
E - [True, False]
E + [True, True]
```
We don't actually wait that l2's gossipd has also processed the message.

`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.

Still writing the channel since some of the channel setup parameters
depends on `chan->id` to be set. If we later set the `chan->id`
signatures fail. This prevents OPENINGD channels showing up after
restarting.

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.

We log at a higher level when we have problems, and also just fail if
master behaves, rather than complaining and hanging.

If needed, they should be directly #included; otherwise the following

When a serialized length refers to an array of structures, the trivial
DOS prevention can be out by a factor of sizeof(serialized struct). Use
the size of the serialized structure as a multiplier to prevent this.
Transaction inputs are the motivating example, where the check is out by
a factor of ~40.
Sometimes the super-low-fee commitment tx succeeds, and we see
that 'sendrawtx exit 0' instead of the one we're expecting.

fundrawtransaction returns before the actual sendrawtx, so we can
end up mining blocks before it's sent, thus not having enough confirms.
We handle this correctly in fund_channel, but this test open-codes it
for speed with multiple peers.

* Add optional addresstype param to newaddr, which can be one of:
- bech32
- p2sh-segwit
- nothing (defaults to p2sh-segwit)
The naming here mirrors bitcoind
* txfilter already looks for p2wpkh outputs, so we're covered there

Commit a57a2dcb86 introduced a time_t

fixes the build on FreeBSD.

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:
