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
since they look for the old onchaind messages.
In particular, when we can't afford the fee we want, we back off to
the next blockcount estimate, rather than spending all on fees
(necessarily). So test_penalty_rbf_burn no longer applies.
Changelog-Changed: Protocol: spending unilateral close transactions now use dynamic fees based on deadlines (and RBF), instead of fixed fees.

Changelog-Added: JSON-RPC: `feerates`: added `floor` field for current minimum feerate bitcoind will accept

And consolidate descriptions into lightning-feerates().

Changelog-Added: JSON-RPC: `close`, `fundchannel`, `fundpsbt`, `multifundchannel`, `multiwithdraw`, `txprepare`, `upgradewallet`, `withdraw` now allow "minimum" and NN"blocks" as `feerate` (`feerange` for `close`).
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*.

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.

Using single tuples in Python is ugly, so:
1. Rename wait_for_onchaind_tx to wait_for_onchaind_txs.
2. Make it take tuples explicitly.
3. Make wait_for_onchaind_tx a simpler wrapper/unwrapper.

We can no longer grab the tx in one line as we did with
wait_for_onchaind_broadcast, we need to track the broadcast from
lightningd.

Changelog-Changed: msggen: The generated interfaces `cln-rpc` anc `cln-grpc` can now work with a range of versions rather than having to match the CLN version
The patching system allows us to enrich the raw schema with some
additional information. In this specific case we want to backfill the
`added` and `deprecated` fields for the multiversion support.
CI seems to block; Christian suggests the throttler may be to blame somehow?
Since trying to fix it made it worse, let's just remove it.

When doing the updates on the plugin repo, I discovered that
this helper function got broken by the `listpeerchannels` upgrade.
Its rarely used in the main repo, just at the end of the pyln-testing
'pay' helper.
If unfixed, this bug may result in test flakes when using the `pay`
helper, because its not correctly waiting for all HTLCs to be resolved
before returning.
Changelog-None
It's a core concept in the spec which isn't directly exposed.

Changelog-Added: JSON-RPC: `listchannels` added a `direction` field (0 or 1) as per gossip specification.
We didn't actually populate them properly, and the real annotations
are on inputs and outputs.

Changelog-EXPERIMENTAL: JSON-RPC: `listtransactions` `channel` and `type` field removed at top level.
