Rusty Russell 3f0c5b985b commando: add filtering support.
1. When we receive a commando command from a remote using the `filter`
   field, use it.
2. Add a `filter` parameter to `commando` to send it: this is usually
   more efficient than using filtering locally.

Of course, older remote nodes will ignore the filter, but that's
harmless.

Rusty Russell 1e3cb01546 bolt12: import the latest spec, update to fit.
I know this is an unforgivably large diff, but the spec has changed so
much that most of this amounts to a rewrite.

Some points:
* We no longer have "offer_id" fields, we generate that locally, as all
  offer fields are mirrored into invoice_request and then invoice.
* Because of that mirroring, field names all have explicit offer/invreq/invoice
  prefixes.
* The `refund_for` fields have been removed from spec: will re-add locally later.
* quantity_min was removed, max == 0 now mean "must specify a quantity".
* I have put recurrence fields back in locally.

Rusty Russell 5becfa6ee1 onion_message: don't use general secret, use per-message secret.
We had a scheme where lightningd itself would put a per-node secret in
the blinded path, then we'd tell the caller when it was used.  Then it
simply checks the alias to determine if the correct path was used.

But this doesn't work when we start to offer multiple blinded paths.
So go for a far simpler scheme, where the secret is generated (and
stored) by the caller, and hand it back to them.

We keep the split "with secret" or "without secret" API, since I'm
sure callers who don't care about the secret won't check that it
doesn't exist!  And without that, someone can use a blinded path for a
different message and get a response which may reveal the node.

Rusty Russell 4cfd972407 common/blindedpath: expose API at a lower level.
We actually want lightningd to create these, since it wants to put the

Christian Decker e1fc88ff70 cln-plugin: Prep the logging payload in a let

Christian Decker 064a5a6940 cln-plugin: Add log filtering support
We filter based on the environment variable `CLN_PLUGIN_LOG`,
defaulting to `info` as that is not as noisy as `debug` or `trace`, at
least libraries will not spam us too heavily.

Changelog-Added cln-plugin: The logs level from cln-plugins can be configured by the `CLN_PLUGIN_LOG` environment variable.

Christian Decker 8898511cf6 cln-plugin: Defer binding the plugin state until after configuring
We had a bit of a chicken-and-egg problem, where we instantiated the
`state` to be managed by the `Plugin` during the very first step when
creating the `Builder`, but then the state might depend on the
configuration we only get later. This would force developers to add
placeholders in the form of `Option` into the state, when really
they'd never be none after configuring.

This defers the binding until after we get the configuration and
cleans up the semantics:

 - `Builder`: declare options, hooks, etc
 - `ConfiguredPlugin`: we have exchanged the handshake with
   `lightningd`, now we can construct the `state` accordingly
 - `Plugin`: Running instance of the plugin

Changelog-Changed: cln-plugin: Moved the state binding to the plugin until after the configuration step

Rusty Russell 6338758018 gossmap: make API more robust against future changes.
Many changes to gossmap (including the pending ones!) don't actually
concern readers, as long as they obey certain rules:

1. Ignore unknown messages.
2. Treat all 16 upper bits of length as flags, ignore unknown ones.

So now we split the version byte into MAJOR and MINOR, and you can
ignore MINOR changes.

We don't expose the internal version (for creating the map)
programmatically: you should really hardcode what major version you
understand!

Rusty Russell f52ff07558 lightningd: allow delpay to delete a specific payment.
This is actually what the autoclean plugin wants, especially since
you can't otherwise delete a payment which has failed then succeeded.

But insist on neither or both being specified, at least for now.

Changelog-Added: JSON-RPC: `delpay` takes optional `groupid` and `partid` parameters to specify exactly what payment to delete.

Rusty Russell 4d8c321517 libplugin: optimize parsing lightningd rpc responses.
autoclean was using 98% of its time in memmove; we should simply keep
an offset, and memmove when it's empty.  And also, only memmove the
used region, not the entire buffer!

Running on product of giantnodes.py:

	$ time l1-cli autoclean-once failedpays 1
	{
	   "autoclean": {
	      "failedpays": {

	      }
