c46473e615 lightningd: allow "NNblocks" and "minimum" as feerates.
And consolidate descriptions into lightning-feerates().

Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Added: JSON-RPC: `close`, `fundchannel`, `fundpsbt`, `multifundchannel`, `multiwithdraw`, `txprepare`, `upgradewallet`, `withdraw` now allow "minimum" and NN"blocks" as `feerate` (`feerange` for `close`).

64b1ddd761 lightningd: clean up feerate handling, deprecate old terms.
Drop try_get_feerate() in favor of explicit feerate_for_deadline() and
smoothed_feerate_for_deadline().

This shows us everywhere we deal with old-style feerates by names.

`delayed_to_us` and `htlc_resolution` will be moving to dynamic fees,
so deprecate those.

Note that "penalty" is still used for generating penalty txs for
watchtowers, and "unilateral_close" still used until we get zero-fee
anchors.

Changelog-Added: JSON-RPC: `feerates` `estimates` array shows fee estimates by blockcount from underlying plugin (usually *bcli*).
Changelog-Changed: JSON-RPC: `close`, `fundchannel`, `fundpsbt`, `multifundchannel`, `multiwithdraw`, `txprepare`, `upgradewallet`, `withdraw` `feerate` (`feerange` for `close`) value *slow* is now 100 block-estimate, not half of 100-block estimate.
Changelog-Deprecated: JSON-RPC: `close`, `fundchannel`, `fundpsbt`, `multifundchannel`, `multiwithdraw`, `txprepare`, `upgradewallet`, `withdraw` `feerate` (`feerange` for `close`) expressed as, "delayed_to_us", "htlc_resolution", "max_acceptable" or "min_acceptable".  Use explicit block counts or *slow*/*normal*/*urgent*/*minimum*.

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.

faae44713b lightningd: clarify uses of dynamic (mempool) feerate floor, and static.
We have the FEERATE_FLOOR constant if you don't care, but usually you want
to use the current bitcoind lower limit, so call get_feerate_floor()

6799cd5d0b plugins/bcli: move commit-fee (dev-max-fee-multiplier) and into core.
Turns out the two bcli replacements I checked (`sauron` and
`trustedcoin`) don't even implement this, and the multiplier makes
more sense in lightningd, especially as we move to bcli just providing

5bdd532e70 onchaind: use lightningd to sign and broadcast htlc_timeout transactions.
This breaks tests/test_closing.py::test_onchain_all_dust's accouting
checks.

That test doesn't really test what it claims to test; sure, onchaind
*says* it's going to ignore the output due to high fees, but the tx
still gets mined.

I cannot figure out what the test is supposed to look like, so I
simply disabled the accounting checks :(

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.

45193db7ea lightningd: add initializing state.
Importantly, the code in jsonrpc.c which actually does the io_break:

```
	/* Once the stop_conn conn is drained, we can shut down. */
	if (jcon->ld->stop_conn == conn && jcon->ld->state == LD_STATE_RUNNING) {
		/* Return us to toplevel lightningd.c */
		log_debug(jcon->ld->log, "io_break: %s", __func__);
		io_break(jcon->ld);
```

By having the state not set until later, we avoid running this.  Of course,
we need to avoid calling the main loop when we get there, if we've already
been told to shutdown.

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.

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

```

21a1b4e6aa common: update HSM_MIN_VERSION to reflect reality.
We were handing 3 to hsmd (and Ken added that in 7b2c5617c1,

355a7ae827 pay: fix delpay to actually delete.
It works for the trivial case, where groupid and partid are the same,

See: #5835
Changelog-Fixed: `delpay`: actually delete the specified payment (mainly found by `autoclean`).
