Use json_scan(), and use the new pay_flow_from_notification() routine.
Also, the tal_dup_or_null can be tal_dup, since &preimage is never NULL.

There are a few fields in `struct renepay` which are genuinely
transient, but it makes the code much harder to follow than simply
having a single structure.
More cleanups will follow, but this is the minimal set.

The general pattern for xxx_new is that it should populate all
fields, for encapsulation and so you never can have a half-formed
object.
This means a fair bit of work for now, but it pays off in the next
patch.

You cannot refresh the gossmap with localmods applied, nor apply localmods
when others have applied localmods in the same process.
There are optimizations we could do, but for now always apply/unapply before
querying gossmap.

dump_our_gossip() is mainly useful for propagating our gossip when we
are poorly connected, not when we have many peers. @whitslack
reported excessive memory use queueing messages on a large node, so we
limit it beyond the first 5 peers, to 5 channels each.
This assumes we have ~ the same number of peers as channels, which
is probably reasonable.
In the long term, we should move this to connectd, which is properly
equipped to trickle out these messages.

This was recommended by @t-bast: if the final spec commits to something
compatible, we can simply advertize and accept both features, but if it
does change in incompatible ways we won't cause problems for nodes
who implement the official spec.
(I split this, so first, we remove the OPT_SPLICE entirely, to make
sure we caught them all. --RR)

We've stomped errno, so if exec fails we don't get a reliable result:

EXPERIMENTAL_SPLICING=1 turns it on for *all* tests, to make sure we don't
accidentally break those. But we can (and should!) run the splice test
under every possible CI scenario.

The nomenclature confusion mean that we were ANDING a capability
with a message number (29) which always returned non-zero. We really
do need a new capability which we can hand to channeld to make these
splice txs.

I obviously like the word "capabilities" since I reused it to refer
to the HSM's overall features :(

In general, futures produced by most libraries in the ecosystem of Rust, and bounds placed
on users of famous runtimes like tokio and its spawn method all lack Sync requirements.
Because of this, anyone who creates a callback using any sort of library that returns a
non-Sync future (which most libraries fit this description) inside of it will get some
cryptic error messages (async error messages still leave a lot to be desired).
Removing these Sync requirements will make the library more useful.
Apparently MacOS doesn't always have fdatasync, so use fsync. Even more importantly
check whether it succeeds!

I noticed this while debugging an issue with ACINQ, that we got upset,
but didn't trigger a reconnect cycle.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Fixed: Protocol: We now close connection with a peer if adding an HTLC times out (which may be a TCP connectivity issue).
This make ACINQ seize up, and not send revoke_and_ack. Eventually,
this can cause a bad signature error, should payments go in both
directions, which is a separate bug, but this is the trigger.

We use this file as a proxy for breaking changes in the signer
protocol. It may not catch all the breaking changes, but it's a
good first approximation.
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.
