Rusty Russell 6275dd384c lightningd: deprecate listconfigs direct fields.
Changelog-Deprecated: JSON-RPC: `listconfigs` direct fields, use `configs` sub-object and `set`, `value_bool`, `value_str`, `value_int`, or `value_msat` fields.

Rusty Russell 9cb2b2f13a listconfigs: show plugin options in 'configs' with normal options.
This integrates them with configvars properly: they almost "just work"
in listconfigs now, and we don't put them in a special sub-object
under their plugin.

Unfortunately, this means `listconfigs` now has a loose schema: any
plugin can add something to it.

Changelog-Fixed: Plugins: reloaded plugins get passed any vars from configuration files.
Changelog-Deprecated: Config: boolean plugin options set to `1` or `0` (use `true` and `false` like non-plugin options).

Rusty Russell b9270c564a lightningd: listconfigs update, using configvars code.
listconfigs is convenient, but it doesn't handle multi-options well: it
outputs an object with duplicate fields in this case (e.g. log-file), nor
is it extensible to show more than raw values.

However, listconfigs doesn't do what other list commands do (use a
sub-object "configs") so we can put the new values under that.

Rusty Russell edbaa944da lightningd: switch parsing to common/configvar
Now we wire in the code which gathers configvars and parses from there;
lightningd keeps the array of configuration variables for future use.

Note that lightning-cli also needs to read the config, but it has its
own options (including short ones!) and doesn't want to use this
configvar mechanism, so we have a different API for that now.

Rusty Russell 6d0b46c9b1 wireaddr: clean up option parsing, support `dns:` prefix directly.
This is a major cleanup to how we parse addresses.

1. parse_wireaddr now supports the "dns:" prefix to support dns records (type 5).
2. We are less reliant on separate_address_and_port() which gets confused by
   that colon.
3. We explicitly test every possible address type we can get back from
   parsing, and handle them appropriately.

We update the documentation to use the clearer HOSTNAME vs DNS prefixes now
we also have `dns:` as a prefix.

Rusty Russell 1b6ff0b2fc staticbackup: don't use wireaddr_internal.
This is an internal type: it has no API guarantees (indeed, I'm about
to change it, which is how I discovered scb was using it).

Fortunately for every case we care about, it is actually a wireaddr
(in theory the peer can connect locally using a local socket, but this
is mostly for testing and is a very strange setup, and so simply don't
do scb for those).

In this case, the wire encoding is a single byte followed by the
wireaddr, so open-code that in scb_wire.csv for compatibility.

Rusty Russell cfa33ce362 lightningd: fix incorrect reuse of dualopend, leading to dev_queryfeerates race
CI hit this issue where it would get a tx_abort in fundchannel.  This
happens when the dualopend we use to query the feerates has not exited
yet (it waits for the tx_abort reply), and we mistakenly reuse it.

With multi-channel support, this is wrong: just run another one and it
all Just Works.

This means we need to rework our dual_open_control.c logic, since it
would previously create an unsaved channel then not clean up if
something went wrong.

Most people will never try to negotiate opening multiple channels to
the same peer at the same time (vs. having an established channel and
opening a new one), so this case is a bit weird.

```
         rates = l1.rpc.dev_queryrates(l2.info['id'], amount, amount)
     
         # l1 leases a channel from l2
         l1.rpc.fundchannel(l2.info['id'], amount, request_amt=amount,

Vincenzo Palazzo 3a2b703ff8 jsonrpc: Remove the old "_msat" prefix in the listpeerchannels command
This is a regression that we introduced in this release
due to some dirty parts of our codebase.

For historical reasons (I think), we were using a `json_add_sat_only`
procedure defined in `peer_control.c`. So when @rustyrussell removed the _msat,
we thought that all the fields were reflecting the new behavior, but
we were wrong.

This PR fixes this bug and also removes the additional function
from `peer_control.c`. This way, we can be sure that there is no other part
of our codebase that uses this method (except for other `json_add` methods).

Now we've set everything up, the replacement code is quite simple.

Some tests now have to deal with RBF though, and our rbf tests need work

Rusty Russell cdb85d5618 lightningd: handle fees as blockcount + range.
Rather than have specific-purpose levels, have an array of
[blockcount, feerate], and rebuild the specific-purpose levels
for now on top.

We also keep a *separate* smoothed feerate, so you can ask for that
explicitly.

Since all the plugins used the same formula to derive the different
named fee levels, we apply the reverse to return to the underlying
estimates: updating the interface comes next.

This is ugly for now, but various specific-purpose levels will be
going away, as we shift to deadline-driven fees.

This temporarily breaks the floor calculation, so that test is
disabled.

Rusty Russell 956e6c4055 lightningd: handle first case of onchaind handing a tx to us to create.
We add code for the case of spending a (timelocked) to-us output of an
HTLC output, so lightningd can do it (rather than onchaind doing all
the work itself).

onchaind still needs to know whether we bothered to create the tx
(fees might have caused it to evaporate, so it should consider it
immediately resolved rather than waiting for it), and what the
witnesses were, and which parts of the witnesses were signatures (as
these parts might change, with RBF or in future, combining other txs).

The inputs (known to onchaind) and the witnesses (told by lightningd)
uniquely identify the spend for the purposes of onchaind.  In
particular, they definitely distinguish HTLC-timeout and HTLC-success
cases.

		log_debug(jcon->ld->log, "io_break: %s", __func__);
		io_break(jcon->ld);

Rusty Russell f2f02f9de6 chaintopology: allow minblock for broadcast_tx.
Fun story.  We're changing onchaind to hand txs to us, and we will
construct them and do the broadcast for it.  lightningd tells onchaind
the witness it used (with flags to indicate which fields were
signatures so should be ignored) so onchaind can recognize the tx
when/if it is mined.

And when onchaind was waiting for a CLTV delay, it wouldn't tell
lightningd yet, but wait until the parent was sufficiently deep

But this caused bugs!

In particular, on replay, onchaind would see transactions which it
hasn't sent yet.  This was not a problem before, as onchaind had
created the tx, even if it hadn't told lightningd to broadcast it, so
recognized the variant when it came in.  When we're relying on
lightningd to tell us what the tx will look like, this doesn't work
any more.

The cause of this is that we fire off txowatches ("this output was
spent!") while we process blocks, and only fire off txwatches ("this
tx increased depth") once all the current blocks are processed.  Often
this didn't matter, since we replay messages to onchaind from the
database, *but* we trim the last few blocks on restart (or, if there's
a small reorg while we're stopped), and we can hit this misordering.

Changing our topology code to only ever process one block at a time
would be a solution, but slows down catchup (and tests, where we often
mine a run of blocks).

So, this seems like a premature optimization, but it's really
required!  And in future, lightningd can use this knowledge of pending
transactions to combine them in more clever ways.

Note that if a tx is valid at block N, we broadcast it once we see
block N-1, to get it in the mempool for block N.

Vincenzo Palazzo b92b9f074d delpay: delete the payment by status from the db
There are cases (difficult to reproduce with a test) where
a payment will fail one time and succeed later.

As far I understand in this case the groupid field of the payment
is the same, and the only thing that change is the status, so
our logic inside the delpay is ambiguous where it is not
possible to delete a payment as described in https://github.com/ElementsProject/lightning/issues/6114

A sequence of commands that explain the problem is

```
$ lc -k listpays payment_hash=H
{
   "pays": [
      {
         "bolt11": "I",
         "destination": "redacted",
         "payment_hash": "H",
         "status": "complete",
         "created_at": redacted,
         "completed_at": redacted,
         "preimage": "P",
         "amount_msat": "redacted",
         "amount_sent_msat": "redacted"
      }
   ]
}
$ lc delpay H complete
{
   "code": 211,
   "message": "Payment with hash H has failed status but it should be complete"
}
```

In this case, the delpay is not able to delete a payment because the
listpays is returning only the succeeded one, so by running the
listsendpays we may see the following result where our delpay logic
will be stuck because it works to ensure that all the payments stored
in the database has the status specified by the user

```

acknowledge blocks before updating blockheight: this resolved a problem
which lnprototest had where it wanted to know when we'd fully digested

gossipd, so this stayed at zero.  We should use the current blockheight
for that corner case!
