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).
Fixes: #6440
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.
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.
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.
Note that this requires more mocks in wallet/test/run-db.c...

Changelog-Added: JSON-RPC: `setchannel` adds a new `ignorefeelimits` parameter to allow peer to set arbitrary commitment transaction fees on a per-channel basis.
`struct log` becomes `struct logger`, and the member which points to the
`struct log_book` becomes `->log_book` not `->lr`.
Also, we don't need to keep the log_book in struct plugin, since it has
access to ld's log_book.

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 avoids the mess where we override db_fatal for teqsts, and keeps it
generic.
Also allows us to get rid of one #if DEVELOPER, and an ugly global for
bookkeeper.

In most cases, it's the same as option_anchor_outputs, but for
fees it's different. This transformation is the simplest:
pass it as a pair, and test it explicitly.
In future we could rationalize some paths, but this was nice
and mechanical.

We don't actually use it anywhere, but we actually want to now for
CPFP. So give it more parameters and make it return bool so it can
be set without necessarily suppressing rexmit.

1. Make it the standard "return the error" pattern.
2. Rather than flags to indicate what types are allowed, have the callers
check the return explicitly.
3. Document the APIs.

Fun story. We're changing onchaind to hand txs to us, and we will
construct them and do the broadcast for it. lightningd tells onchaind
the witness it used (with flags to indicate which fields were
signatures so should be ignored) so onchaind can recognize the tx
when/if it is mined.
And when onchaind was waiting for a CLTV delay, it wouldn't tell
lightningd yet, but wait until the parent was sufficiently deep
But this caused bugs!
In particular, on replay, onchaind would see transactions which it
hasn't sent yet. This was not a problem before, as onchaind had
created the tx, even if it hadn't told lightningd to broadcast it, so
recognized the variant when it came in. When we're relying on
lightningd to tell us what the tx will look like, this doesn't work
any more.
The cause of this is that we fire off txowatches ("this output was
spent!") while we process blocks, and only fire off txwatches ("this
tx increased depth") once all the current blocks are processed. Often
this didn't matter, since we replay messages to onchaind from the
database, *but* we trim the last few blocks on restart (or, if there's
a small reorg while we're stopped), and we can hit this misordering.
Changing our topology code to only ever process one block at a time
would be a solution, but slows down catchup (and tests, where we often
mine a run of blocks).
So, this seems like a premature optimization, but it's really
required! And in future, lightningd can use this knowledge of pending
transactions to combine them in more clever ways.
Note that if a tx is valid at block N, we broadcast it once we see
block N-1, to get it in the mempool for block N.

At the moment only lightingd needs it, and this avoids missing any
places where we do bip32 derivation.
This uses a hsm capability to mean we're backwards compatible with older

Changelog-Added: Protocol: we now always double-check bitcoin addresses are correct (no memory errors!) before issuing them.
It's needed as the db and wallet is being set up (db migrations), so
it's simpler this way to always use ld->bip32_base for the next patch.

Header from folded patch 'fix-hsm-check-pubkey.patch':
fixup! hsmd: capability addition: ability to check pubkeys.
It's not likely but possible that the node's settings will shift btw a
start and an RBF; we persist the setting to the database so we don't
lose it.
Right now holding onto it forever is kind of extra but maybe we'll
reuse the setting for splices? idk.
Should this be a channel type??
technically we don't need this info after the channel opens, but for any
subsequent RBF (and maybe splice?) we need to remember what the
open/accept peer signaled
We need to be able to only use non-wrapped inputs for v2/interactive tx
protocol.
Changelog-Added: JSONRPC: `fundpsbt` option `nonwrapped` filters out p2sh wrapped inputs
After connecting 100,000 peers with one channel each (not all at

This current spec is not strict enough: we might complain that the
next peer is not connected, for example, which leaks information.
So return WIRE_INVALID_ONION_BLINDING even if we're the first hop
on the path, to be safe.

Otherwise what the hook sees is actually a lie, and if it sets it
we might override it.
The side effect is that we add an explicit "forward_to" field, and
allow hooks to override it. This lets a *hook* control channel
choice explicitly.
