This is how we put new invoice_requests into the db; this will be used
by a new "invoicerequest" command which replaces "offerout".
The API is now the same as the offers api.

We no longer use offers for "I want to send you money", but we'll use
invoice_requests directly. Create a new table for them, and
associated functions.
The "localofferid" for "pay" and "sendpay" is now "localinvreqid".
This is an experimental-only option, so document the change under
experimental only.

Changelog-EXPERIMENTAL: JSON-RPC: `pay` and `sendpay` `localofferid` is now `localinvreqid`.
We no longer have to refer back to the offer for which we're making
the invoice_request, or to the invoice_request we made for an invoice,
as they are all mirrored (and we check!).
It's clearer to simply look at the object directly.

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.

add explicit invoice_node_id.")

It's just to a direct peer, and we only create one, but this is
enough to test, and make payments to non-public nodes work.

This is needed for offers to generate blinded paths.
No documentation changes since listincoming is an undocumented
internal hack interface which topology presents for production
of routehints.

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.

We actually want lightningd to create these, since it wants to put the
path_id secret in the last element. So best API is actually a generic
one, rather than separate APIs to create first and last ones.
And really, the more explicit initialization makes the users clearer.

We simply take the first one, and route to the start of that. Then we
append the blinded path to the onion construction.

Since the "struct command" is different from plugins and lightningd, we
need an accessor for this to work (the plugin one is a dummy for now!).

Changelog-EXPERIMENTAL: Protocol: Support for forwarding blinded payments (as per latest draft)
We need to print out first_node_id, and "node_id" is now called
"blinded_node_id" in the spec.
And the schema didn't include the payment fields in the blinded path
for invoices (which broke as soon as we actually tested one!).

It's 2b7ad577d7a790b302bd1aa044b22c809c76e49d, which reverts the
point32 changes.
It also restores send_invoice in `invoice`, which we had removed
from spec and put into the recurrence patch.
I originally had implemented compatibility, but other changes
which followed this are far too widespread.

Changelog-EXPERIMENTAL: offers: complete rework of spec from other teams (yay!) breaks previous compatibility (boo!)
We use the saved previous outputs (plus maybe some new ones?) to build a
psbt for an RBF request.
RBFs utxo reuse is now working so we can unfail the test (and update
it to reflect that the lease sticks around through an RBF cycle).

Changelog-Fixed: Plugins: `keysend` now removes unknown even (technically illegal!) fields, to try to accept more payments.
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.
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
We will now simply reject old-style ones as invalid. Turns out the
only trace we could find is a channel between two nodes unconnected to
the rest of the network.
