We need to upgrade the rust version of the ubuntu docker images as
time-core v0.1.2 needs a version newer than 1.67.0

The fedora image installs a setuptools version that can not be upgraded
via pip. A fix is to remove the files manually and reinstall it via pip.

Code using `CI_SERVER` was added recently to track something. It
attempts to short-cut if `CI_SERVER` is not set, but on gitlab it
is set to `yes`. https://docs.gitlab.com/ee/ci/variables/
Instead use `CI_SERVER_URL`, maybe that is what is intended?
If we disconnect, we lose the open_attempt record. Which is fine, but we
should prevent the user from starting another RBF if the last one isn't
done yet!
Originally the accepter waited for the peer to send us their commitment
sigs before we send ours; this changes things so that the accepter
sends their commitment sigs ASAP.
This test fails: when cln is not the channel initiator, it waits for the other node to send commit_sig before sending its own commit_sig. There is no reason to do that, both nodes should send commit_sig immediately after exchanging tx_complete? Otherwise it's a missed opportunity to finalize the channel creation on reconnection, because in that case cln hasn't saved the channel and fails it on reconnection.

When we got our peer's sigs, if we were the remote, we would re-notify
the plugin, which in turn would re-send the tx-sigs to use.
In the case of CLN, we'd then
- break, because we'd re-forward the sigs to the `openchannel` plugin,
which was then in the wrong state (MULTIFUNDCHANNEL_SIGNED)
spenderp: plugins/spender/openchannel.c:598: json_peer_sigs: Assertion `dest->state == MULTIFUNDCHANNEL_SECURED' failed.
spenderp: FATAL SIGNAL 6 (version 5880d59-modded)
In the case of eclair, they'd just see our 2nd TX_SIGS message and
@t-bast would complain:
> This test works, with one minor issue: on reconnection, cln sends its tx_signatures twice (duplicate?).
This commit does two things:
- has the openchannel / spender plugin log a broken instead of
crashing when the state is not what we're expecting
- stops us from calling the `funder` plugin if this is a
replay/second receipt of commit-sigs.
Here we conform to the specification, which requires that we handle
next-funding-id in a specific way.
Note that we were already sending it, but now we actually correctly
handle its presence.
Changelog-Changed: Spec: dual-funding now follows the next-funding-id rules.
In the case where you're echoing back a tx-abort, just let it through.
Not doing this causes problems in the case where your node has forgotten
about an in-progress open.
This fixes the following problem:
- you send a tx-abort (even tho you have marked tx-sigs as received)
- peer echos it back (we echo back tx-aborts always)
- you throw an error because you're already in a tx-abort unallowed
state
In this commit, we allow for echos to come thru no matter our current state and
this fixes things/makes them work as expected.
If you get the right series of disconnects, it's possible for your peer
to send you a tx-sigs even though the current state of the channel open
is that you've seen the funding open on chain (your channel_ready[LOCAL]
= true)
In this case, if we haven't marked that we've seen the tx sigs yet,
we go ahead and mark them as seen and just ignore this tx-sigs msg.
If we get a commitment-signed message from a peer, outside of a normal
flow, process it!
We're about to send these during reconnect, so we need to be able to
handle them!
We're going to need to reuse this for reconnect; make the method
standalone in that it can figure out what to send to HSMD independent of
where it's located in the setup call flow.
We need to keep track of if we've gotten the last negotiation's
commitment sigs, for reconnect logic (helps us know what messages to
send in the reconnect case)
If an openchannel_update fails (due to disconnect etc) it's possible
that it could 'resolve' itself later due to the auto reconnect logic
If you call an openchannel_update and we've already got an inflight
record saved, go ahead and return the info from the inflight (including
info about whether or not the commitments are secured.)
This makes openchannel_update a bit more 'robust'/idempotent, in that
you can make repeat calls to it after the channel is inflight and get
the info you need back to continue (call openchannel_signed)
Changelog-Changed: RPC: `openchannel_update` will now echo back a result if there's a matching inflight record for this open.
Since we can now get a COMMITMENT_SIGNED message due to a reconnect,
in addition to the 'inline' open process, it's possible that we might
have cleaned up / lost the open_attempt object.
This is fine, we have (almost) all the data we need to round this off
successfully/send out a notice.
Note that the only exception is the `close_to` data is lost/forgotten in
the case of a restart; this is largely fine.
If the peer's disconnected but the caller sends us valid sigs for the
channel open, we should go ahead and store them to disk before we reject
the call based on the fact that the peer is disconnected.
This way if the peer reconnects later, the channel open will succeed
Changelog-Changed: RPC: `openchannel_signed` will now remember the details of a signed PSBT even if the peer is disconnected.
When we reconnect, if we get a note from the peer that they dont know
about a pending inflight, we need to be able to clean it up so we can
restart/re-negotiate a new RBF etc.
This adds a cleanup method to remove any inflights for a channel without
a last_tx (commitment tx)
We don't actually use this internal to this method? Weird.
Anyway, if we don't want/need it allow the caller to signal that by
passing in NULL, if desired.
Here, we split up what was "commit_received" into two phases:
- commit-ready, where we're about to send our commitment tx to
peer
- commit-received, when we've gotten the commitment tx from our
peer
This lets us do the right thing (as far as the spec is concerned) with
returning the correct 'next_funding_txid' on reconnect (later commits).
From the spec:
Once peers are ready to exchange commitment signatures, they must remember
the details of the funding transaction to allow resuming the signatures
exchange if a disconnection happens.
Basically this means we add channels to the database before we've gotten
commitments for them; it's nice that there's now a state for commitments
recevied but we now save the channel prior to that.
This commit makes it possible to track the pre-commit-rcvd but not quite
open-init state.

Changelog-Changed: Config: `large-channels` is now the default, wumbology for all.
Adding a fee offset as the channel opener reduces the likelihood of a
disconnect by the peer do to slight variation in feerate calculation
between nodes.
Changelog-Fixed: Some peer disconnects due to update_fee disagreements are avoided.
