It only works on BOLT11, and has long been replaced by the more
generic "decode".
Removing it will stop the confusion!
(Note: documentation claims it was introduced in 23.08, but that was
wrong, as it's been in CLN since the beginning).

Christian noted that if we don't do this we could flood onchaind with messages:
particularly in Greenlight where the HSM (remote) may delay indefinitely, so
onchaind doesn't process messages.

This means it always tells us explicitly whether to keep watching or not,
and we know it's processed it.

This may help the cases we see where gossipd doesn't realize channels
are closed (because of shutdown before it processed the closing).
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Fixed: `gossipd` will no longer miss some channel closes on restart.
And we hook in the replay watch code.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Fixed: `onchaind` can miss conclusion of final txs in some cases, will now replay independently.
We start by telling onchaind about the funding spend, and anything
which spends it, and it tells us the txids it *doesn't* want to watch
any more. We're going to use a separate set of watches for the replay
case: this implements that code.
Once we're caught up, we convert any remaining watches to normal ones
to follow future blocks.

And use it for `exposesecret-passphrase`. This is probably overly
cautious, but it makes me feel a little better that we won't leak it
to someone with read-only access.

The ability to stfu channels in bulk is required to do complex multi channel operations. When stfu’ing in this manner, the available funds at the moment of stfu is returned to the user.
In order to cancel the stfu we also add a bulk tx_abort command.
Changelog-Added: `stfu_channels` and `abort_channels` are added for bulk multi-channel splice commands. These allow the user to pause (and resume) multiple channels in place.
This is needed to all multi-channel splices. When channeld can return the signatures to the user (based on signing order precedent), it now does from splice_update.
Additionally, we move sending of the initial psbt from splice_init down to splice_update. This is also necessary for correct psbt diff detection during multi-channel splices.
Changelog-Changed: splice_update can in some cases now return the remotely partiall signed psbt to the user, if so `signtures_secured` will be true.
`splice_signed` now searchs the PSBT for channel ids
Changelog-Changed: `splice_signed` parameters are switched in order to make `channel_id` an optional parameter, enabling multi-splice-signatures.
On `dev-memleak`, if someone is using rpc_command_hook, we'll call
it when the hook returns. But it will see these contexts as a leak.
So attach them to tmpctx (which is excluded from leak detection).

This is like `sendonion` but unwraps the onion as the first hop,
avoiding nasty special cases for blinded paths which start with this
node, and also self-pay.
Tests split into multiple ones after Christian's review.
Changelog-Added: JSON-RPC: `injectpaymentonion` for initiating an HTLC like a peer would do.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Don't assume we have an outgoing HTLC at this level.
Note that previously we didn't save the failed onion unless it was
unparsable: we keep that both for space savings and because our
`waitsendpay` logic assumes that when it fetches from the db if
there's a failonion it was unparsable!
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
This message is supposed to include the msat amount received. But this is
obviously per-HTLC, and we hacked it to use the value for the first one.
And we add logging whenever we fail an HTLC set, since we removed logging
by not calling failmsg_incorrect_or_unknown() (which, now, no longer needs
to log).

Removes the `COMPAT_V070` functionality for `listfowards`.
Changelog-Changed: The `listforwards` command will now return a value
of 0 for `received_time` for very old forward attempts.
Changelog-Added: JSON-RPC: `decode` now used modern BOLT 4 language for blinded paths, `first_path_key`.
Changelog-Deprecated: JSON-RPC: `decode` `blinding` in blinded path: use `first_path_key`.
Changelog-Added: Plugins: `onion_message_recv` and `onion_message_recv_secret` hooks now used modern BOLT 4 language for blinded paths, `first_path_key`.
Changelog-Deprecated: JSON-RPC: `onion_message_recv` and `onion_message_recv_secret` hooks `blinding` in blinded path: use `first_path_key`.
No code changes, just catching up with the BOLT changes which rework our
blinded path terminology (for the better!).
Another patch will sweep the rest of our internal names, this tries only to
make things compile and fix up the BOLT quotes.
1. Inside payload: current_blinding_point -> current_path_key
2. Inside update_add_htlc TLV: blinding_point -> blinded_path
3. Inside blinded_path: blinding -> first_path_key
4. Inside onion_message: blinding -> path_key.
5. Inside encrypted_data_tlv: next_blinding_override -> next_path_key_override

On my local machine, it also warns in param_dev_channel, so I fixed that too.

This name is clearer than the old one.
And since the struct contains a string, it's more natural for the
struct to be the tal parent of the string so it's a real object. This means
we need an array of pointers, so each struct can be its own tal object.
wallet_state_change_get is hoisted higher in the code and made static.

And instead of loading them in listpeerchannels, use them. This means
listpeerchannels no longer touches the db.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Fixed: JSONRPC: `listpeerchannels` (and thus, pay) sped up on very large nodes.
Indirection via a string and an enum is just adding confusion here.
And move the `struct channel_stats` into channel.h.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
This avoids a db lookup on every iteration of listpeerchannels, which
can be slow on large nodes (Postgres, I assume).
We can now simply add the fields we want to channel load, and remove
wallet_channel_stats_load entirely.

Rather than making the callers do this, make the invoice decoder perform

I used `amount_msat_eq(x, AMOUNT_MSAT(0))` because I forgot this
function existed. I probably missed it because the name is surprising,
so add "is" in there to make it clear it's a boolean function.
You'll note almost all the places which did use it are Eduardo's and
Lisa's code, so maybe it's just me.
Fix up a few places which I could use it, too.

This was incorrect once we stopped removing old payments on failure,
which was the reason we had to remove the HTLCs.
It also removed by partid, which is wrong since it should have done
old_payment->partid and old_payment->groupid!
