fa33a2fece lightningd: make plugins set metadata for invoice requests.
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).

55982fe549 offers: generalize "best peer" logic into core.
We use this for invoices published by unannounced nodes: want
something very similar for offers, so generalize and expose it.

27578d5c1d plugins/offers: add dev-paths option for specifying offers blinded paths.
This will let us test, at least, as we implement fetching invoices from
them.

a43705194d plugins/offers: make send_onion_reply() handle making transient connections.
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.

8c81d6a0b9 plugin/offers: add inject_onionmessage helper.
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".

a782ea75b5 plugins: move fetchinvoice functionality into offers plugin.
This means only a single gossmap, and they already share the fetchinvoice-noconnect option

Changelog-EXPERIMENTAL: We will now reply to invoice_request messages even if reply path requires us to make an outgoing connection (LDK does this)

401f1debc5 common: clean up json routine locations.
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)

20392ae526 connectd: restore obs2 onion support.
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.

e7b263304e lightningd: Send updated onion spec messages.
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.
