In this case, the user's default was info, but they specifically asked for debug
from one plugin. Since there were no per-file filters, it set filtering to the
default level, info, and rejected it. Since it's been explicitly filtered in,
we need to pass it at this point.

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).

Thread the signed tx through so close's JSON return contains that,
rather than the unsigned channel->last_tx.
We have to split the "get cmd_id" from "resolve the close commands" though;
and of course, as before, we don't actually print the txids of multiple
transactions even though we may have multi in flight due to splice!

Changelog-Fixed: JSON-RPC: `close` returns a `tx` field with witness data populated (i.e. signed).

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.
Update gossip routiens and various other hecks on the channel state to consider AWAITING_SPLICE to be routable and treated similar to CHANNELD_NORMAL.
Small updates to psbt interface
Changelog-None
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.

Clean restart of daemon after a tx-abort is a nice way to work around
the 'persistent' disconnect that we t-bast noticed.
Changelog-Fixed: `dualopend`: Fix behavior for tx-aborts. No longer hangs, appropriately continues re-init of RBF requests without reconnction msg exchange.
This will at least *help* the case where these were not populated, causing us
to send errors without channel_updated appended.
It's not perfect: we can still send such errors if the gossip store is
corrupted, and we still send them for private channels, but it should
help.
(The much better fix is far more invasive, so slips to next release!)

This cause of cascading failure was pointed out by @t-bast: if fees spike and
you don't timeout an outgoing onchain HTLC, you should nonetheless fail the incoming htlc
because otherwise the incoming peer will close on you.
Of course, there's a risk of losing funds, but this only happens if you weren't going to get the HTLC spend in time anyway. And it would also catch any other reason that the downstream onchain goes wrong, containing the damage.

Changelog-Fixed: Protocol: We will close incoming HTLCs early if the outgoing HTLC is stuck onchain long enough, to avoid cascating failure.
This is the simplest solution, not the best, but there's significant risk in try to remove the "we have a path" assumption in the code pay code.
Includes removing a `tal_steal` which was incorrect: the buffer has the same lifetime as the plugin, so if we steal it then things get messy when we free the struct payment.

Changelog-Added: Plugins: `pay` will now pay your own invoices if you try.
Previously, the "payment" and "invoice" paths were completely separate, but this now calls both. It bypasses htlc_sets (and thus, cannot do MPP), and bypasses the hook too: the former is tied closely to HTLCs, and the hook is also very htlc-centric.
Includes finishing unfinished sentence in sendpay man page, as a bonus.

Changelog-Added: Plugins: `sendpay` now allows self-payment of invoices, by specifying an empty route.

If they have invalid runes, we bail, but if they have runes which used
a different master secret (old commando.py allowed you to override
secret), we just complain and delete them.

The wallet_datastore_first() SELECT statement only iterates from the
given key (if any), relying on the caller to notice when the key no
longer applies. (e.g. startkey = ["foo", "bar"] will return key
["foo", "bar"] then ["foo", "bar", "child" ], then ["foo", "baz"]).
The only caller (listdatastore) would notice the keychange and stop
looping, but reallly wallet_datastore_next() should do this. When I
tried to use it for migrations, I got very confused!
Also, several places want a simple "wallet_datastore_get()" function,
so provide that.

At cold start, if your node is behind the blocktip and you've sent your
peer a blockheight counter from the future, we shouldn't confuse ourselves
with our rollback/replay.
Should fix flakes in CI that were spotting BROKEN blockheight updates.
Logs below from a previuos CI fail (edited for relative clarity)
The one that sasy "{ SENT_ADD_ACK_REVOCATION:111 }, our current 108` is
the tell; the last line is the node finally catching up to the tip.
In the test we get into this state by stopping and restarting the node.

We get intermittant reports of subd->conn being leaked, but I could never find it.
That's because it's actually subd which is not referenced any more: subd->conn
gets reported because it's subd's tal_parent (and, except for the reference in
subd, not referenced either).
The real issue is that the channel->owner is reassigned to the new subdaemon,
and the old one is still exiting. During that time, we can see a "leak".

The channel selection did not consider the amounts that we are trying
to transfer, which in a multiplexed channel world could end up always
selecting a channel that is too small for the payment. We also log
which channel was selected based on the selector that is passed in,
allowing us to better follow the decisions.
Changelog-Fixed: pay: `sendonion` and `sendpay` will now consider amounts involved when using picking one channel for a peer
