Changelog-Fixed: Plugins: we clean up properly if a plugin fails to start, and we don't kill all processes if it's from `plugin startdir`.
Don’t send the funding spend to onchaind if we detect it in inflights (aka. a splice). While we already prevented onchaind_funding_spent from being called directly, the call to wallet_channeltxs_add meant onchaind_funding_spent would be called *anyway* on restart. This is now fixed.
Additionally there was a potential for a race problem depending on the firing order of the channel depth and and funding spent events.
Instead of requiring these events fire in a specific order, we make a special “memory only” inflight object to prevent the race regardless of firing order.
Changelog-Fixed: Splice: bugfix for restart related race condition interacting with adversarial close detection.
In spec commit 498f104fd399488c77f449d05cb21c0b604636a2 (August 2021),
Bastien Teinturier removed the requirement that the mutual close fee be
less than or equal the final commitment tx.
We adopted that change in v0.10.2, but we made sure to never offer a fee
under the final commitment tx's fee, so we didn't break older nodes.
However, the closing tx can actually be larger than the final commitment tx!
The final commit tx has a 22-byte P2WKH output and a 34-byte P2WSH output;
the closing can have two 34-byte outputs, making it 4*8 = 32 Sipa heavier.
Previously this would only happen if both sides asked for P2WSH outputs,
but now it happens with P2TR, which we now do.
The result is that we create a tx which is below the finally commitment
tx fee, and may be below minrelayfee (as it was in regtest).
So it's time to remove that backwards-compatibility hack.
Changelog-Fixed: Protocol: We may propose mutual close transaction which has a slightly higher fee than the final commitment tx (depending on the outputs, e.g. two taproot outputs).

The main function here is payment_reconsider:
* Each payment has a list of pay_flow.
* This is populated in try_paying(), calling add_payflows & sendpay_new_flows.
* When we get a notification, we resolve a pay_flow using one of the pay_flow_failedxxx
or pay_flow_succeeded functions.
* They call payment_reconsider() which cleans up finished flows decides what to do:
often calling try_paying again.

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

our code assumes a 2-byte prefix anyway).

Thread the signed tx through so close's JSON return contains that,

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.
Bug Report:
- initiate a channel open eclair -> cln
- wait for the transaction to be published
- eclair initiates rbf, and cancels it by sending tx_abort before exchanging commit_sig
- at that point everything looks good, cln echoes the tx_abort and stays connected
- eclair initiates another RBF attempt and sends tx_init_rbf: for some unknown reason,
cln answers with channel_reestablish (??) followed by an error saying
"Bad reestablish message: WIRE_TX_INIT_RBF"
Diagnosis:
CLN is doing a reconnect after a tx-abort is sent.
Extra Test:
Realized that if we abort, we won't correctly advanced to NORMAL if
blocks are mined while we're in hanging state. CLN should advance
after block containing channel open is mined.

Changelog-Changed: Reckless can now install directly from local sources.
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 commit addresses an issue to enhance the resilience of core
lightning when receiving node announcements.
According to BOLT 7 (The announcement_signatures Message),
if the node_signature OR the bitcoin_signature is NOT correct,
it is recommended to either send a warning and close the connection or send an error and fail the channel.
In this commit, we take a strict approach. If any error is detected, we
send an error and fail the open channel operation.
This is because the announcement_signatures operation is optional,
and we assume that it must be correct.

Previously, our code checked for the presence of the `lightning:`
prefix while decoding a bolt11 string. Although this prefix is valid
and accepted by the core lightning pay command, it was causing issues
with how we managed invoices. Specifically, we were skipping the prefix
when creating a copy of the invoice string and storing the raw invoice
(including the prefix) in the database, which caused inconsistencies
in the user experience.
To address this issue, we need to strip the `lightning:` prefix before
calling each core lightning command. In addition, we should
modify the invstring inside the db with the canonical one.
This commit fixes the issue by stripping the `lightning:` prefix
from the `listsendpays` function, which will improve the
user experience and ensure consistency in our invoice management (see
next commit).

Having the grpc bindings in the pyln-testing package was always a bit
strange, however it came with additional issues. Due to the way that
protos are handled by protobuf, any name clash, independently of where
we import the protos, would cause an import error. This usually
happens in diamond-pattern dependencies, and so pull out the generated
files into their own package that everyone else can rely on.

Add a fuzz test for BOLT 8 message encryption and decryption. The fuzz

When core lightning is asking the information about
the blockchain with `getchaininfo` command lightningd
know already the information about the min and max block height.
the problem is when we have a smarter Bitcoin backend that is able
to switch between different clients in some cases is helpful
give the information about current known height by lightningd and
pass it down to the plugin.
In this way, the plugin knows what is the correct known height from lightnind, and can
try to fix some problems if any exit.
This is particularly useful when you are syncing a new backend from scratch
like https://github.com/cloudhead/nakamoto and we avoid returning the
lower height from the known, and avoid the crash of core lightning.
With this information, the plugin can start to sync the chain and return
the answer back only when the chain is in sync with the current status of
lightningd.
Another reason to add this field and not wait the correct block in core
lightning itself is because Bitcoin Core is extremely slow to sync up,
so the question here is, how long should we wait? The time depends
on various factors.
With this approach of informing the plugin about the height, in some cases,
you can start the syncing but move the execution to another backend until
the previous one is ready.
The problem I want to solve is that I don't want to be left in the dark when
we run `getchaininfo`, and I want to have the opportunity to wait for
the blockchain sync or decide to dispatch the request elsewhere.
Changelog-Added: Pass the current known block height down to the getchaininfo call.

Changelog-Deprecated: Config: boolean plugin options set to `1` or `0` (use `true` and `false` like non-plugin options).
We use multi-specifiable options elsewhere, this is just another.
Otherwise you can't add, you can only set them all.

listconfigs is convenient, but it doesn't handle multi-options well: it
outputs an object with duplicate fields in this case (e.g. log-file), nor
is it extensible to show more than raw values.
However, listconfigs doesn't do what other list commands do (use a
sub-object "configs") so we can put the new values under that.

Changelog-Added: JSON-RPC: `listconfigs` now has `configs` subobject with more information about each config option.
Now we wire in the code which gathers configvars and parses from there;
lightningd keeps the array of configuration variables for future use.
Note that lightning-cli also needs to read the config, but it has its
own options (including short ones!) and doesn't want to use this
configvar mechanism, so we have a different API for that now.

This adds:
1. ability to search for an option by name.
2. allowance to set our own bits when registering options.

These are only likely to confuse users, by silently changing behavior.
Changelog-Deprecated: Config: bind-addr=xxx.onion and addr=xxx.onion, use announce=xxx.onion (which was always equivalent).
Changelog-Deprecated: Config: addr=/socketpath, use listen=/socketpath (which was always equivalent).
This obsoletes the use of --announce-addr-dns which I know Michael
didn't really like either.
Changelog-Deprecated: Config: `announce-addr-dns`; use `--bind-addr=dns:ADDR` for finer control.

CI hit this issue where it would get a tx_abort in fundchannel. This
happens when the dualopend we use to query the feerates has not exited
yet (it waits for the tx_abort reply), and we mistakenly reuse it.
With multi-channel support, this is wrong: just run another one and it
all Just Works.
This means we need to rework our dual_open_control.c logic, since it
would previously create an unsaved channel then not clean up if
something went wrong.
Most people will never try to negotiate opening multiple channels to
the same peer at the same time (vs. having an established channel and
opening a new one), so this case is a bit weird.
```
rates = l1.rpc.dev_queryrates(l2.info['id'], amount, amount)
# l1 leases a channel from l2
l1.rpc.fundchannel(l2.info['id'], amount, request_amt=amount,

We need to check that the key is valid for two reasons:
1) towire_ext_key() aborts if the key is invalid
2) fromwire_ext_key() doesn't check the parsed key for validity
Since bip32_key_get_fingerprint() fails if the key is invalid, we can
call it first to guarantee the key is valid before serializing.
When we release too fast, the plugin crashes:
```

This was pointed out by Daywalker [1]: we are synchronously processing
events from `lightningd` which means that if processing one of the
hooks or requests was slow or delayed, we would not get notifications,
hooks, or RPC requests, massively impacting the flexbility.
This highlights the issue with a failing test (it times out), and in
the next commit we will isolate event processing into their own task,
so to free the event loop from having to wait for an eventual
response.

We were in fact feeding l1 its own gossip, which it doesn't ratelimit (this was
a bit fuzzy before, but definitely is the case now!).

This test makes l2 save db, make a payment, then rollback.
*Sometimes* under CI (but not here) we don't shutdown fast enough
after the payment, so the moves.json from the coin_movements.py
records it. Sure enough, the result is the node ends up with
a -10000msat balance.
Validated by putting a time.sleep(5) between:
```
l2.rpc.pay(inv['bolt11'])
import time
time.sleep(5)
# stop both nodes, roll back l2's database
```
The answer, of course, is to save and rollback *both* the db and
moves.json file.
Here's the error:

Now we've set everything up, the replacement code is quite simple.
Some tests now have to deal with RBF though, and our rbf tests need work
since they look for the old onchaind messages.

the next blockcount estimate, rather than spending all on fees
(necessarily). So test_penalty_rbf_burn no longer applies.
