This could have been a local static but its used by the run-param test,
so putting it in json.c made things easier.

Note: Unlike before, this will now accept positional parameters.
Note: In case of error we no longer report the hop number. Is this acceptable?
We still report the name of the bad param and its value.
One option is to log the hop number if param() returns false. This would require
a change to command_fail so it doesn't delete the cmd, so we can still
access cmd->ld->log.

The `json_tok_X` functions now consistently check the success case first
and call `command_fail` at the end.

It's probably unnecessary to have this weird way of injecting results
now we have explicit feerate args.

We could refine this later (based on existing wallet, for example), but
this gives some estimate.

We don't know what our peer is doing, but if we see those values, maybe
they did too, and for longer. And add the min/max acceptable values
into our JSON API.

This is useful mainly in the case where bitcoind is not giving estimates,
but can also be used to bias results if you want.

And no more filtering out messages, as we should no longer spam the
logs with them (the 'Connected json input' one was removed some time
ago).

1. Move the list to the start of `struct peer`: memleak walks the
list correctly this way.
2. Don't create tal parent loop daemon->conn->daemon.
The second one is silly anyway: we exit via master_gone when the master
conn is closed.

We're going to call out to subds for memleak detection, and the disabler
looks like a memleak if we're inside a callback.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
memleak can't see into htables, as it overloads unused pointer bits.
And it can't see into intmap, since they use malloc (it only looks for tal
pointers).

We use feerate in several places, and each one really should react
differently when it's not available (such as when bitcoind is still
catching up):
1. For general fee-enforcement, we use the broadest possible limits.
2. For closingd, we use it as our opening negotiation point: just use half
the last tx feerate.
3. For onchaind, we can use the last tx feerate as a guide for our own txs;
it might be too high, but at least we know it was sufficient to be mined.
4. For withdraw and fund_channel, we can simply refuse.

Manipulate fees via fake-bitcoin-cli. It's not quite the same, as
these are pre-smoothing, so we need a restart to override that where
we really need an exact change. Or we can wait until it reaches a
certain value in cases we don't care about exact amounts.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Not just during startup: we could have bitcoind not give estimates until
later, but we don't want to smooth with zero.
The test changes in next patch trigger this, so I didn't write a test
with this patch.

We don't respond to fee changes until we're locked in: make sure we catch
up at that point.
Note that we use NORMAL fees during opening, but IMMEDIATE after, so
this often sends a fee update. The tests which break, we set those
feerates to be equal.
This (sometimes) changes the behavior of test_permfail, as we now
get an immediate commit, so that is fixed too so we always wait for
that to complete.

This is a noop if we're opening a new channel (channel_fees_can_change(channel)
is false until funding locked in), but important if we're restarting.

When in this state, we send a canned error "Awaiting unilateral close".
We enter this both when we drop to chain, and when we're trying to get
them to drop to chain due to option_data_loss_protect.
As this state (unlike channel errors) is saved to the database, it means
we will *never* talk to a peer again in this state, so they can't
confuse us.
Since we set this state in channel_fail_permanent() (which is the only
place we call drop_to_chain for a unilateral close), we don't need to
save to the db: channel_set_state() does that for us.
This state change has a subtle effect: we return WIRE_UNKNOWN_NEXT_PEER
instead of WIRE_TEMPORARY_CHANNEL_FAILURE as soon as we get a failure
with a peer. To provoke a temporary failure in test_pay_disconnect we
take the node offline.

This means we don't try to unilaterally close after a restart, *and*
we can tell onchaind to try to use the point to recover funds when the
peer unilaterally closes.
