9b8909e507 dual-fund: keep track of aborted requests, seamlessly restart daemon
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.

c807db4b7f dual-fund tests: add tests for reported incompat with Eclair
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.

73a67fbb3e funder: don't re-reserve utxos on retries
This way unreserving the PSBT will work as intended, and we don't have
to keep track of how many times we've called reserved for any one input.

Technically we're supposed to not reserve inputs at *all* while doing
opens, this moves us slightly closer to that.

955afdeea8 gossipd: set timer for node_announcement regen
Also as update_own_node_announcement is called nearly continuously
under normal operation by maybe_send_own_node_announce, the timer should
not be freed continuously - better to only free before actually
refreshing.

4b4937b9bd gossipd: tell lightningd about all our previous channel_updates at startup.
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!)

c98711ad28 lightningd: don't crash if peer manages to spend onchain HTLC after we've abandoned upstream.
Since we now abandon HTLCs to avoid breaking a channel (in limited circumstances), the
peer can take the funds if they beat us to spend the HTLC before we timeout.  This is extremely
unusual, but finally happend in CI.

First it fails our internal sanity checks, but then it would fail when we tried to fulfill
an already-failed HTLC:

f51ce7be85 pytest: follow RBF txids properly, but ignoring identical "RBF" txs.

978c1699ea lightningd: fail incoming HTLCs if peer would close channel.
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.

af71fd689a onchaind: keep trying to collect HTLC even if we're past timeout.
The test actually triggers this:
1. We don't get our commitment tx mined at all (we block it).
2. By the time the peer does, the HTLC is expired.
3. We have the preimage but we don't even try, since it's expired.

We should at least *try* to collect the HTLC in this case.

f4fd12cc15 channeld: Verify the signature sent by the counterparty
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.

lnprototest at commit dea47c29b5541dbfe7fe53cc2598330e897fa4f4 report
the following error now.

620135335d libplugin/pay: allow shortcut for self-pay.
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.

18760db66d lightningd: sendpay implement zero-length path == self-pay.
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.

07e00d50c6 invoice: return error string from invoice_check_payment.
Clean these up: they were debug logs, but we want to pass this information
back for self-payments.

Also fixes "Attept" typo which altered tests!
