In 6e4ff6a7d2 ("offers: add a blinded path
if we have no advertized address") we were overzealous, and set blinded
paths not just for offers and invoicerequests, but for invoices themselves.
This has revealed various interop issues (which is great, but not good
for our users!) so we should disable that. It also reduces the reliability
of payments in general.
Changelog-None: fixes previously overzealous addition

Fixes: https://github.com/ElementsProject/lightning/issues/7806
Changelog-Changed: Offers: we will use a blinded path if we have no advertized address (so payers wouldn't be able to connect directly).
Without knowing what method was called, we can't have useful general logging
methods, so go through the pain of adding "const char *method" everywhere,
and add:
1. ignore_and_complete - we're done when jsonrpc returned
2. log_broken_and_complete - we're done, but emit BROKEN log.
3. plugin_broken_cb - if this happens, fail the plugin.

They can do it now: before it would have been awkward to look up previous
payments to match it up for recurring offers (which need to use the same
key, hence the same invreq_metadata).

Changelog-Added: Protocol: pay can now pay to bolt12 invoices if entry to blinded hop is specified as a short_channel_id (rather than node id).

We use this for invoices published by unannounced nodes: want
something very similar for offers, so generalize and expose it.

And make it use inject_onionmessage. This means we have to be more careful
in createinvoice_done where we had a payload field allocated off tmpctx.
The new code correctly handles the case where we find a path (not just
a peer!) to the start of a blinded path, and need to join the paths.
It worked before if we had to connect directly, just not in the case
where we actually found a usable route of more than 1 hop.
Changelog-EXPERIMENTAL: fixed: onionmessage replies now work even if we need to route to the start of the blinded reply path.

This will obsolete the existing calls to RPC "sendonionmessage", but
we transition by introducing it separately. It's designed to work with
the common/onion_message routines and "injectonionmessage".

This means only a single gossmap, and they already share the fetchinvoice-noconnect option
and autoconnect code.

Changelog-Changed: Plugins: the `fetchinvoice` plugin has been combined into the `offers` plugin.
You can disable this with `fetchinvoice-noconnect`.
Changelog-EXPERIMENTAL: We will now reply to invoice_request messages even if reply path requires us to make an outgoing connection (LDK does this)

Mainly, field name changes.

Changelog-EXPERIMENTAL: Protocol: Support for forwarding blinded payments (as per latest draft)
We have them split over common/param.c, common/json.c,
common/json_helpers.c, common/json_tok.c and common/json_stream.c.
Change that to:
* common/json_parse (all the json_to_xxx routines)
* common/json_parse_simple (simplest the json parsing routines, for cli too)
* common/json_stream (all the json_add_xxx routines)
* common/json_param (all the param and param_xxx routines)

I removed these prematurely: we *haven't* had a release since
introducing them!
This consists of reverting d15d629b8b
"plugins/fetchinvoice: remove obsolete string-based API." and
plugins/fetchinvoice: remove obsolete string-based
API. "onion_messages: remove obs2 support."
Some minor changes due to updated fromwire_tlv API since they
were removed, but not much.

Changelog-EXPERIMENTAL: REVERT: Removed backwards compat with onion messages from v0.10.1.
It's very similar to the previous, but there are a few changes:
1. The enctlv fields are numbered differently.
2. The message itself is a different number.
The onionmsg_path type is the same, however, so we keep that constant
at least.
The result is a lot of cut & paste, but we will delete the old one
next release.

Temporarily disable sendpay_blinding test which uses obsolete onionmsg;
there's still some debate on the PR about how blinded HTLCs will work.
