bf549130d6 global: update BOLT12 quotes.
This is a final sweep to match the current BOLT12 text:

	1563d13999d342680140c693de0b9d65aa522372 ("More bolt12 test vectors.")

Only two code changes, to change the order of checks to match the bolt,
and to give a warning on decode if a path is empty.

d740795139 common/bolt12: allow missing offer_issuer_id.
The latest spec allows this to be omitted iff there is a blinded path
and it would be made up anyway.

In that case, the key they will use to sign the invoice will be the final
blinded key in the path we use.

0d4b9ad6ce offers: check they use the blinded path if one is specified.
Now we can specify a blinded path in an offer, we have to check they
used it (or didn't use it, if we didn't have one!).

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.

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.

a770f51d0e tools/generate_wire.py: make functions allocate the TLV.
Requiring the caller to allocate them is ugly, and differs from
other types.

This means we need a context arg if we don't have one already.

fa0c29f959 tools/generate_wire.py: tlvs should start with tlv_
No more "towire_offer", but "towire_tlv_offer".

This means we double-up on the unfortunately-named `tlv_payload` inside
the onion, but we should rename that in the spec when we remove
old payloads.

4ffda340d3 check: make sure all files outside contrib/ include "config.h" first.
And turn "" includes into full-path (which makes it easier to put
config.h first, and finds some cases check-includes.sh missed
previously).

config.h sets _GNU_SOURCE which really needs to be done before any
'#includes': we mainly got away with it with glibc, but other platforms
like Alpine may have stricter requirements.

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.
