This provides a sanity check that we are in sync, and also keeps the
logic in the program and out of the SQL.
Since the destructor now doesn't clean up the peer, there are some
wider changes to be made when cleaning up. Most notably we create
lots of channels in run-wallet.c and they previously freed the peer:
now we need free the peer explicitly, so we need to free them first.

And return the correct error message for the channel they give, if
they try to re-establish on an error channel.

Channels are within the peer structure, but the peer is freed only
when the last channel is freed.
We also implement channel_set_owner() and make peer_set_owner() a temporary
wrapper.

Much like the database; peer contains id, address, channel contains
per-channel information. Where we create a channel, we always create
the peer too.
For the moment, peer->log and channel->log coexist side-by-side, to
reduce some of the churn.
Note that this changes the API to dev-forget-channel: if we have more
than one channel, we insist they specify the short-channel-id.

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.

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.

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.

This makes much more sense when you ask for a specific peer's log.
Also, we put the peerid rather than pid ().

The JSON connect command wouldn't terminate if peer reconnected
in a state CHANNELD_AWAITING_LOCKIN or above.
