9aefe3d40a common: update to latest onion-message spec.
```
make check-source-bolt CHECK_BOLT_PREFIX="--prefix=BOLT-onion-message" BOLTVERSION=guilt/offers
```

Mainly textual, though I neatened the extra fields check for TLVs with
blinding, and implemented the "no other fields" requirement for
non-final onion message hops.

4cfd972407 common/blindedpath: expose API at a lower level.
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.

2760490d5d common: catch up on latest routeblinding spec.
This makes us match eed2ab0c30ad7f93e3b2641ca9d7ade32f3d121d
("Use `invalid_onion_blinding` everywhere").

1. Numerous typographical changes.
2. Make sure we *always* return WIRE_INVALID_ONION_BLINDING if
   we're in a blinded path.
3. Handle p->total_msat correctly (MPP payments).
4. Reorganize blinding handling just like spec order.

It's a premature optimization, and it make modifications more complex.

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.

83ee68ab06 common/tlvstream: put TLV checking back in the generic function.
Callers were supposed to call "tlv_fields_valid" after fromwire_tlv,
but few did.  Make this the default, and call the underlying function
directly where we want to be more flexible (one place).

This loses the ability to allow misordered fields, or to pass through
*any* even fields.  We restore that for special cases in the next
patch.

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.

b3af5f5a2c spec: import latest onionmessage spec, based on routeblinding.
This is from 6e99c5feaf60cb797507d181fe583224309318e9

We renamed the enctlv field to encrypted_recipient_data in the spec, and the
new onion_message is message 513.  We don't handle it until the next patch.

Two renames:
1. blinding_seed -> blinding_point.
2. enctlv -> encrypted_recipient_data.

We don't do a compat cycle for our JSON APIs for these experimental
features only used by our own plugins, we just rename.
