9fd29d35dd common: move now-enlarged command_fail_badparam into its own source file.
It's getting a bit awkward to inline now: it's non-trivial.

f33c5188ef common: don't mention the contents of invalid parameters when in non-dev mode.
Shahana decided this was the optimal UX path, though I insisted that we still
report the actual problem directly when in dev mode, as a compromise.

001b190c61 feat(main): Print channel status when loading it from DB
I was trying to debug a node with several multiplexed channels, and
was finding it a bit difficult to determine which channel index
matches which result of `listpeerchannels` as well as figuring out
what their status was. This just prints the status in string format
when loading the channel from the DB.

Changelog-Changed: wallet: The channel status is printed when loading it from the DB

7f2aedc76f common: BOLT update: option_anchors_zero_fee_htlc_tx is now simply "option_anchors".
This is a difficult transition for us: this string appears in channel
types.  We make the transition now in the understanding that it will
be more difficult in future.

Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

Changelog-Deprecated: JSON-RPC: `listpeers` `features` array string "option_anchors_zero_fee_htlc_tx": use "option_anchors" (spec renamed it).
Changelog-Added: JSON-RPC: `listpeers` `features` array string uses "option_anchors" for feature 22/23, following renaming in BOLT 9.
Changelog-Changed: JSON-RPC: `listclosedchannels`, `listpeerchannels`, `openchannel_update`, `openchannel_init`, `fundchannel`, `fundchannel_start` and `multifundchannel`: `channel_type` array `names` now contains "anchors" instead of "anchors_zero_fee_htlc_tx".
Changelog-Changed: lightningd: `--list-features-only` now lists "option_anchors" instead of "option_anchors_zero_fee_htlc_tx".

7d3d763b96 channeld: BOLT update, no longer allow creation of old (experimental-only!) non-zero-fee anchor channels.
These were removed from the spec.

We still support existing ones, though we were the only implementation
which ever did, and only in experimental mode, so we should be able to
upgrade them and avoid a forced close, with a bit of engineering...

1d4783a756 lightningd: send CHANNEL_REESTABLISH ourselves on closed channels.
We used to fire up channeld to send this, but:
1. That's silly, we have all the information to make it ourselves.
2. We didn't do it if there was an error on the channel, which as of 24.02
   there always is!
3. When it did work, running channeld *stops* onchaind, indefinitely slowing recovery.

0946a5ac35 lightningd: clean up notification infrastructure.
The `struct notification` lost type-safety, but avoided a redundant
string.  The string is better, I think.

Since all notifications now contain an object of same name (some have
deprecated fields outside that), we can add helpers to do that, too.

Also, add some const (easy to do now we're typesafe!)

e9ff50df96 hsmd: Implement hsmd_forget_channel for Channel Deletion in HSMD
Changelog-Added: hsmd: Added hsmd_forget_channel to enable explicit channel deletion. ([#6987])

Motivation: Previously, a signer prematurely forgetting a channel led
to failures in unresolved channel requests. This update introduces
hsmd_forget_channel, allowing nodes to explicitly notify signers when
a channel is irrevocably resolved and can be safely forgotten. This
ensures synchronized channel cleanup between nodes and signers.

This change maintains backward and forward compatibility. Nodes
explicitly check whether a signer has `WIRE_HSMD_FORGET_CHANNEL`
capability before sending the message.  Nodes without
`WIRE_HSMD_FORGET_CHANNEL` capability won't send this message. Signers
capable of handling this message but not receiving it will continue to
use conservative pruning methods.

Fixes #6987

Not just when it's a private channel.  This is useful for listpeerchannels in the next patch.

a6a9e5b1e3 splice: Reestablish when commit or sig sends fail
Adds tests for when the connection fails during
1) splice tx_signature
2) splice commitment_signed

Fleshed out the reestablish flow for these two cases and implemented the fixes to make these reestablish flows work.

Part of this work required changing commit process for splices: Now we send a single commit_part for the splice where previously we sent all commits, and accordingly, we no longer revoke in response.

Changelog-Fixed: Implemented splicing restart logic for tx_signature and commitment_signed. Splice commitments are reworked in a manner incompatible with the last version.

52b1ba2992 wallet: remove premature optimization when making payment.
We didn't write to db immediately, but waited until it the actual HTLC got
added (or failed).  That way we didn't have a separate transaction to
write the payment into the db, but the complexity is not worth it: it
makes the next refactors harder, since we can't use the normal
iterator patterns like we do with the rest of the db (as we have to add
the unstored ones).

We might as well also make sendpay return immediately: we used to return
once the HTLC had been confirmed sent, since we entered it in the db
at that point, but we can keep it simple now.
