And deprecate the --max-locktime-blocks which allows them to set it.
Hilariously, the spec misspells CLTV as CTLV at one point, so we work around it for now.

1024 is a common limit, and people are starting to hit that many channels, so we should increase it: twice the number of channels seems reasonable, though we only do this at restart time.
Changelog-Changed: lightningd: we now try to increase the number of file descriptors, if it's less than twice the number of channels at startup (and log if we cannot!).

We wire through --dev options into the hsmd, and test preapprove accept and deby

Now we can check that the setconfig would actually parse. We do this
by handing NULL to the calback to indicate it's a test, which may not
work in general but works for now.

Changelog-Added: `check` `setconfig` now checks that the new config setting would be valid.
We were duplicating the command name (e.g. "autocleaninvoice.autocleaninvoice"), and also not
handling listconfigs if they specified the (currently unused!) i-promise-to-fix-broken-api-user
option, which we are going to use next patch.

We still want to test non-anchor channels, as we still support them, but
we've made it non-experimental. To test non-anchor channels, we
use dev-force-features: -23.

I did some CHANGELOG and git digging to see when these were deprecated, and
some were very old (v0.8.2!). But since they didn't warn users loudly, I
chose to do so this release only.
I renamed ld's `deprecated_apis` to `deprecated_ok` to make sure I
caught them all.

This allows the user to specify the feature *by name*, and hopefully
complain to the developer to fix their code, knowing it will be removed entirely
in the next release!
Changelog-Added: config: `i-promise-to-fix-broken-api-user` allows for a one-release re-enablement of long-deprecated features.

Changelog-Removed: Config: `disable-ip-discovery` (deprecated in v23.02): use `announce-addr-discovered`
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
In the original [$6173] pr `bind` was a typo for `bind-addr`.
`bind` never existed, so this commit updates uses of `bind` to `bind-addr`.
This links lightningd-config.5.md to configuration.md since `bind-addr` has options of interest such as ipv4/ipv6.
Since these worked in v23.08, we can't just rename them. So if they are
used and unclaimed, we should rename them internally (if they're claimed,
it's probably clightning-rest, and we should *NOT* touch them!).

Changelog-Changed: Config: `large-channels` is now the default, wumbology for all.
Adding a fee offset as the channel opener reduces the likelihood of a

This was recommended by @t-bast: if the final spec commits to something
compatible, we can simply advertize and accept both features, but if it
does change in incompatible ways we won't cause problems for nodes
who implement the official spec.
(I split this, so first, we remove the OPT_SPLICE entirely, to make
sure we caught them all. --RR)

This was strongly recommended by Russell O'Connor: the "ms" implies that
it's a BIP-32 master secret, and this is CLN specific.
If we changed the hrp to "cln" it would be better, but apparently that
means we no longer fit in a "standard billfold metal wallet" (and
our code assumes a 2-byte prefix anyway).

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.
Firstly, I wanted the results easier to use:
1. Make them always lower case, even if the string was UPPER.
2. Decode the payload for them.
3. Don't give the user any fields they don't need, and make
the field sizes explicit.
Secondly, I wanted to avoid the pattern of "check in one place, assume
in another", in favour of "check on use".
So, I changed the code to lower the string if it needs to at the start,
and then changed the pull functions so we always use them to get data:
this way we should fail clearly and gracefully if we don't have enough data.
I made all the checks explicit, where we assign the fields.
I also addressed the FIXME: I think the array is *often* one shorter,
but not always, so I trim the last byte at the end if needed.

We usually have access to `ld`, so avoid the global.
The only place generic code needs it is for the json command struct,
and that already has accessors: add one for libplugin and lightningd
to tell it if deprecated apis are OK.

This is the simple version which always tries to keep some sats if we
have an anchor channel. Turns out that we need something more
sophisticated for multifundchannel, so that's next.

Changelog-Changed: JSON-RPC: `withdraw` will refuse to spend funds below `min-emergency-msat` if we have any anchor channels (and `all` will be reduced appropriately).
Changelog-Changed: JSON-RPC: `fundpsbt` and `utxopsbt` will refuse to spend funds below `min-emergency-msat` if we have any anchor channels.
For anchors, we need some sats sitting around in case we need to CPFP

Changelog-Added: Config: `min-emergency-msat` setting for (currently experimental!) anchor channels, to keep funds in reserve for forced closes.
We disabled experimental support for opening non-zero-fee anchor
channels (though old nodes may still have such channels if they turned
that on!).
So we simply call this `experimental-anchors`, since this is the variant
which we expect to be used widely.

Changelog-EXPERIMENTAL: protocol: added support for zero-fee-htlc anchors (`option_anchors_zero_fee_htlc_tx`), using `--experimental-anchors`.
Previously, if these failed we always exited; once we have dymamic

This integrates them with configvars properly: they almost "just work"
