Rusty Russell 37590eeeb2 common: fix arm32 compile breakage.
It's obviously the incorrect type, while our CI didn't catch it, Nicholas did:

```

Rusty Russell 891cef7b2b bolt12: routines to hash the invreq parts.
This gives us a unique identifier, by which we can match an invoice to
their invoice_request.

Rusty Russell 1e3cb01546 bolt12: import the latest spec, update to fit.
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.

This brings us to 655df03d8729c0918bdacac99eb13fdb0ee93345 ("BOLT 12:
add explicit invoice_node_id.")

Rusty Russell 6e755d6fe8 common/bolt12: code to initialize invreqs from offers, invs from invreqs.
This is an important part of the coming spec: we mirror all fields,

Rusty Russell aa73878831 common/bolt12: add code to generate offer_id, extract parts of streams.
The new spec removes the offer_id, in favor of mirroring all the
fields.  So we need a way of generating a convenient identifier to
identify the offer, and this works.

We also want to extract parts of streams elsewhere, so expose that.

Rusty Russell e30ea91908 BOLTs: update to more recent bolt12 spec.
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.

Rusty Russell 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.

Rusty Russell 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.

Rusty Russell 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.
