Adds a "canonical" error handling in the module mcf.c,
adhering to the same convention we have adopted in flow.c.
So that when a function fails it signals the caller with an invalid
return value, or bool false, and it communicates an error message.
This switches the logging implementation from using the `log`-facade
to using the `tracing-subscriber` instead. This allows us to also tap
into the tracing instrumentation if desired, which was not possible
with `log`.
Changelog-Changed cln-plugin: The logging adapter now uses tracing-subscriber allowing the `tracing` ecosystem to be used. No format changes.
The `cln-plugin` can be used to create a plugin that registers
additional rpc-methods. However, it doesn't allow to specify the `usage`
of the command.
This change makes it possible to specify the `usage`. It should not
contain any breaking changes.
I've opted to add a new method called `rpcmethod_from_builder` to the
`Builder` struct. This approach allows us to add new parameters in the
future.

Changelog-Deprecated: `listchannels` no longer uses local knowledge to set `active` to false if disconnected.
This alters a few remaining tests, as well.

Changelog-Deprecated: JSON-RPC: `listchannels` listing private channels: use listpeerchannels
This breaks our tests a bit, which assumed we can always see ourselves
even if we don't have a proper channel.
Usually we would deprecate this first, but it's unlikely to break
anyone since it's a bit obscure that this worked at all.

Changelog-Changed: JSON-RPC: `listnodes` no longer shows private (peer) nodes: use listpeers
We temporarily use a second gossmap so we can just switch private info off
for listincoming and not listchannels.
Note that listchannels now uses the local alias (if no scid), so we have
to change that in the routehint caller.
Since we now *always* use a channel alias in hints if one exists, a
test broke, so fix that.

We will get localmods from gossmods_from_listpeerchannels in the next commit,
so we need to save routehints to add to that later.

We have multiple different routines here, and we want to wean them off private
gossip one at a time. This converts `getroute`.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
This is more thorough than the minimal one required for getroute(), including the feerates
and cltv deltas.

Rusty: I added the bad gossip message so we would see unknown updates in CI, and made sure we don't send our own generated updates to lightningd.

CI revealed one:
```
cc plugins/libplugin-pay.c
plugins/libplugin-pay.c: In function ‘payment_getroute’:

My local compiler gave another:
```

This fixes a crash on startup of core-lightning where gevent could not
be imported. This happens before sys is imported and throws us into the
except clause which calls sys.
By importing it explicitly in the except clause we are not dependend of
the order of imports in the try bracket.

Changelog-Fixes: Plugin: clnrest crashed on startup when gevent was
missing.
Add a version bump for clnrest and the main poetry.lock to the makefile
and update the release checklist to include the new target.

This will allow users to use clnrest with c-lightning-REST without conflicts.
It was required for applications to have enough time for migrating from c-lightning-REST to clnrest.
Changelog-Changed:
config option `rest-certs` changed to `clnrest-certs`
config option `rest-protocol` changed to `clnrest-protocol`
config option `rest-host` changed to `clnrest-host`
config option `rest-port` changed to `clnrest-port`
config option `rest-cors-origins` changed to `clnrest-cors-origins`
config option `rest-csp` changed to `clnrest-csp`
We have a global JSON encoder hack, which means that any field ending in msat gets special treatment (so we can safely talk to lightningd, even if a field expects satoshi amounts, we are explicit). However, requests uses the JSON parser and DOES NOT want this conversion when sending it out as an HTTP response!
The simplest local fix we could find was Shahana's suggestion to iterate and covert away from Millisatoshi(): the reverse of what our JSON encoder does.

It already throws an exception or error, or decodes the JSON response:
we can simply pass it through.

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.
- certificate generation
- config options validation
- log level from 'error' to 'info'
- sending method as None instead ""
- added `listclnrest-notifications` for websocket server rune method
Changelog-Fixed: websocket server notifications are available with
restriction of `readonly` runes
This functionality already exists in the Python framework; this feature
enables it for Rust plugins as well.
Changelog-Added: cln-plugin: Implement send_custom_notification to allow sending custom notifications to other plugins.
