When starting a plugin, if the plugin path cannot be found in
absolute context, assume it is a relative path to the default
plugins dir. As a result, the following now works when my_plugin.py
is installed in the default plugins dir:
lightning-cli plugin start my_plugin.py
Also update the plugin documentation to reflect that the use of a
relative path is now available.
Changelog-Added: plugin start RPC subcommand now assumes relative path to default plugins dir if the path is not found in absolute context. i.e. lightning-cli plugin start my_plugin.py

Instead of doing an allocation per entry, put the entry in directly.
This means only 30 bit resolution on 32-bit machines, but if a bit
of gossip gets accidently suppressed that's ok.

When we moved gossip filtering to connectd, this aging got lost.
Without this, we hit the 10,000 entry limit before expiring full
gossip anti-echo cache. This is under 1M in allocations per peer, but
in DEVELOPER mode each allocation includes adds 3 notifiers (32 bytes
each) and a backtrace child (40 + 40 + 256 bytes), making it almost
10MB per peer, plus allocation overhead.

This likely lead to a number of false errors when attempting to
route. We deemed a channel to be unusable as soon as either direction
isn't usable. This is bad since it excludes not only zeroconf
channels (which have different scids for the two directions), but it
also excludes any channel that we haven't seen an update from
yet. This was likely introduced when attemting to exclude nodes that
haven't sent a disable, but their peer has, but this is not necessary
as the unresponsive node would be marked as isolated by all its peers,
so we don't need to artificially mark a channel direction as disabled
when really we can't even enter the node to traverse the channel in
that direction.
Changelog-Fixed: routing: Fixed an issue where we would exclude the entire channel if either direction was disabled, or we hadn't seen an update yet.
Now it's formatted properly, we don't need the patch.
But we need to explicitly marshal/unmarshal into a byte stream,
which involves some code rearrangement.

This was eliminated this morning in the latest spec. We still accept them,
we just don't produce them any more.

We weren't building the Rust plugins in the `Dockerfile` since we were
missing the dependencies. Now we do.
Changelog-Fixed: docker: The docker images are now built with the rust plugins `cln-grpc`
I have a test which reproduces this, too, and it's been seen in the
wild. It seems we can add a subd as we're closing, which causes
this assert to trigger.

We had multiple reports of channels being unilaterally closed because
it seemed like the peer was sending old revocation numbers.
Turns out, it was actually old reestablish messages! When we have a
reconnection, we would put the new connection aside, and tell lightningd
to close the current connection: when it did, we would restart
processing of the initial reconnection.
However, we could end up with *multiple* "reconnecting" connections,
while waiting for an existing connection to close. Though the
connections were long gone, there could still be messages queued
(particularly the channel_reestablish message, which comes early on).
Eventually, a normal reconnection would cause us to process one of
these reconnecting connections, and channeld would see the (perhaps
very old!) messages, and get confused.
(I have a test which triggers this, but it also hangs the connect
command, due to other issues we will fix in the next release...)

Switching to poetry, and deprecating python 3.6, made things a bit
more tricky. Sadly we'll not be able to build jammy, as its support is
missing in the tag tarball, but it'll be there for the next release.

We call out to connectd to activate the peer, and while we do that,
channel->owner is NULL. A better pattern would be to set up the unsaved
channel once connectd has given us the peer, but this works for now.
