Update the lightningd <-> channeld interface with lots of new commands to needed to facilitate spicing.
Implement the channeld splicing protocol leveraging the interactivetx protocol.
Implement lightningd’s channel_control to support channeld in its splicing efforts.
Changelog-Added: Added the features to enable splicing & resizing of active channels.
The fields were missing because they weren't annotated with a type and
a description. Adding those fixes them.
Changelog-Fixed: msggen: `listpays` now includes the missing `amount_msat` and `amount_sent_msat` fields
No-schema-diff-check: fields were always there, just undocumented!
If you miss a wait event, you can catch up by doing listinvoices and
getting the max of these fields. It's also a good debugging clue.

Now we have defined ordering, we can add a start param.

Changelog-Added: JSON-RPC: `listinvoices` has `index` and `start` parameters for listing control.

Changelog-Added: JSON-RPC: `setchannel` adds a new `ignorefeelimits` parameter to allow peer to set arbitrary commitment transaction fees on a per-channel basis.
This is needed when we know we're *opening* an anchor channel, to
override the "do we already have an anchor channel open?" logic.
Also, document the nonwrapped arg added in v23.02.

Changelog-Added: JSON-RPC: `fundpsbt` and `utxopsbt` new parameter `opening_anchor_channel` so lightningd knowns it needs emergency reserve for anchors.
Since we can CPFP, we don't have to track the feerate as closely. But
it still needs to get in the mempool, so we use 10 sat/byte, or the
100 block estimate if that is higher.

Changelog-Added: JSON-RPC: `feerates` has new fields `unilateral_anchor_close` to show the feerate used for anchor channels (currently experimental), and `unilateral_close_nonanchor_satoshis`.
Changelog-Changed: JSON-RPC: `feerates` `unilateral_close_satoshis` now assumes anchor channels if enabled (currently experimental).
See the section headed "Rules with Grouped Targets" on the Texinfo page
`(make)Multiple Targets`.
Without this fix, Make does not know that these recipes unconditionally
make *all* of their named targets regardless of which target triggers
their execution, and Make will blissfully execute multiple instances of
any such recipe in parallel, not only wasting CPU cycles but potentially
producing incorrect results if the recipe is not atomic in its effects
on the file system. With this fix, Make understands that it need only
execute such a recipe once to make all of its targets.
In pursuit of the above, move and combine two redundant msggen recipes
into the top-level Makefile, and populate its grouped targets from the
subordinate Makefiles.
Changelog-None
This was pointed out by Daywalker [1]: we are synchronously processing
events from `lightningd` which means that if processing one of the
hooks or requests was slow or delayed, we would not get notifications,
hooks, or RPC requests, massively impacting the flexbility.
This highlights the issue with a failing test (it times out), and in
the next commit we will isolate event processing into their own task,
so to free the event loop from having to wait for an eventual
response.

Changelog-Added: JSON-RPC: `feerates`: added `floor` field for current minimum feerate bitcoind will accept
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
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*.

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
There were cases where address it's empty, and this cases are not right if the
field is considered optional.
This makes it required and add the field also when `--offline` is set.
Changelog-Changed: JSON-RPC: `getinfo` `address` array is always present (though may be empty)
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.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-EXPERIMENTAL: JSON-RPC: `listtransactions` `channel` and `type` field removed at top level.
rename is necessary to roundtrip, otherwise the rust name is used.
This also remove the rename if they are not necessary.
Note that:
```
#[serde(rename="foo", skip_serializing_if=="bar")]
pub field: bool,
```
is equivalent to:
```
#[serde(rename="foo")]
#[serde(skip_serializing_if=="bar")]
pub field: bool,
```
and for simplicity of construction the latter is used
