Create a notification that is triggered when a `costummsg` is received.
Changelog-Added: Plugins: notification custommsg for receiving an unknown protocol message
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.
We temporarily use a second gossmap so we can just switch private info off
for listincoming and not listchannels.
Note that listchannels now uses the local alias (if no scid), so we have
to change that in the routehint caller.
Since we now *always* use a channel alias in hints if one exists, a
test broke, so fix that.

This is redundant if it's a public channel, but vital if it's not. Publishing unconditionally makes
it easier for gossmap: we create a local modification all the time, even if redundant (and we can
have the actual capacity ceiling accurate in this case, since we know it for local channels).

Changelog-Added: JSON-RPC: `listpeerchannels` now shows gossip update contents (even if channel unannounced).
Not just when it's a private channel. This is useful for listpeerchannels in the next patch.
Most of this is renaming.
It also means that source can be NULL, so move it out of the struct and put it in the message,
where it logically belongs, and make it an optional field.

Rusty: I added the bad gossip message so we would see unknown updates in CI, and made sure we don't send our own generated updates to lightningd.

Turns out we were sending feerate updates to daemons that do not
understand it. Don't do that!
Closes#6932
Changelog-Fixed: channeld: We could crash `closingd` by sending it a `channeld` message
We were (dumbly?) using the `onchain_hrp` for 'chain_mvts' and the
`lightning_hrp` for 'channel_mvts'.
This works fine everywhere *except* for on a signet, where we use
different prefixes.
Since the lightning-hrp set is more diversified (testnet btc
+ signet btc use the same HRP 'onchain'), let's use that.
Should have zero impact on anything other than nodes running on signet.
To preserve your current accounts database without needing to delete,
restart, execute the following: (note preferrably when your node isn't
running).
```
UPDATE chain_events SET currency = 'tbs' WHERE currency = 'tb';
```
Fixes#6534
Changelog-Fixed: `bkpr-listbalances` would crash for nodes on signet with payments in channels, because onchain events were using a different currency than inchannel events.

Changelog-Fixed: JSON-RPC: Plugin notification `msat` fields in `invoice_payment` and `invoice_created` hooks now a number, not a string with "msat" suffix.

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.
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-Deprecated: Plugins: `clnrest` parameters `rest-port`, `rest-protocol`, `rest-host` and `rest-certs`: prefix `cln` to them
If we disconnect, we lose the open_attempt record. Which is fine, but we
should prevent the user from starting another RBF if the last one isn't
done yet!
When we got our peer's sigs, if we were the remote, we would re-notify
the plugin, which in turn would re-send the tx-sigs to use.
In the case of CLN, we'd then
- break, because we'd re-forward the sigs to the `openchannel` plugin,
which was then in the wrong state (MULTIFUNDCHANNEL_SIGNED)
spenderp: plugins/spender/openchannel.c:598: json_peer_sigs: Assertion `dest->state == MULTIFUNDCHANNEL_SECURED' failed.
spenderp: FATAL SIGNAL 6 (version 5880d59-modded)
In the case of eclair, they'd just see our 2nd TX_SIGS message and
@t-bast would complain:
> This test works, with one minor issue: on reconnection, cln sends its tx_signatures twice (duplicate?).
This commit does two things:
- has the openchannel / spender plugin log a broken instead of
crashing when the state is not what we're expecting
- stops us from calling the `funder` plugin if this is a
replay/second receipt of commit-sigs.
We need to keep track of if we've gotten the last negotiation's
commitment sigs, for reconnect logic (helps us know what messages to
send in the reconnect case)
If an openchannel_update fails (due to disconnect etc) it's possible
that it could 'resolve' itself later due to the auto reconnect logic
If you call an openchannel_update and we've already got an inflight
record saved, go ahead and return the info from the inflight (including
info about whether or not the commitments are secured.)
This makes openchannel_update a bit more 'robust'/idempotent, in that
you can make repeat calls to it after the channel is inflight and get
the info you need back to continue (call openchannel_signed)
Changelog-Changed: RPC: `openchannel_update` will now echo back a result if there's a matching inflight record for this open.
Since we can now get a COMMITMENT_SIGNED message due to a reconnect,
in addition to the 'inline' open process, it's possible that we might
have cleaned up / lost the open_attempt object.
This is fine, we have (almost) all the data we need to round this off
successfully/send out a notice.
Note that the only exception is the `close_to` data is lost/forgotten in
the case of a restart; this is largely fine.
If the peer's disconnected but the caller sends us valid sigs for the
channel open, we should go ahead and store them to disk before we reject
the call based on the fact that the peer is disconnected.
This way if the peer reconnects later, the channel open will succeed
Changelog-Changed: RPC: `openchannel_signed` will now remember the details of a signed PSBT even if the peer is disconnected.
When we reconnect, if we get a note from the peer that they dont know
about a pending inflight, we need to be able to clean it up so we can
restart/re-negotiate a new RBF etc.
This adds a cleanup method to remove any inflights for a channel without
a last_tx (commitment tx)
Here, we split up what was "commit_received" into two phases:
- commit-ready, where we're about to send our commitment tx to
peer
- commit-received, when we've gotten the commitment tx from our
peer
This lets us do the right thing (as far as the spec is concerned) with
returning the correct 'next_funding_txid' on reconnect (later commits).
From the spec:
Once peers are ready to exchange commitment signatures, they must remember
the details of the funding transaction to allow resuming the signatures
exchange if a disconnection happens.
Basically this means we add channels to the database before we've gotten
commitments for them; it's nice that there's now a state for commitments
recevied but we now save the channel prior to that.
This commit makes it possible to track the pre-commit-rcvd but not quite
open-init state.

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
disconnect by the peer do to slight variation in feerate calculation
between nodes.
Changelog-Fixed: Some peer disconnects due to update_fee disagreements are avoided.
This table doesn't have `id`, except as the implicit one in Sqlite3,

On a re-payment where we simply returned from sendpay immediately! Move that log to later.
