Rusty Russell 1d1174c286 offers: use existing copied fields.
We no longer have to refer back to the offer for which we're making
the invoice_request, or to the invoice_request we made for an invoice,
as they are all mirrored (and we check!).

It's clearer to simply look at the object directly.

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 5becfa6ee1 onion_message: don't use general secret, use per-message secret.
We had a scheme where lightningd itself would put a per-node secret in
the blinded path, then we'd tell the caller when it was used.  Then it
simply checks the alias to determine if the correct path was used.

But this doesn't work when we start to offer multiple blinded paths.
So go for a far simpler scheme, where the secret is generated (and
stored) by the caller, and hand it back to them.

We keep the split "with secret" or "without secret" API, since I'm
sure callers who don't care about the secret won't check that it
doesn't exist!  And without that, someone can use a blinded path for a
different message and get a response which may reveal the node.

Rusty Russell 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.

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 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.

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.

Rusty Russell 6aa520bb9b lightningd: remove sendonionmesage parity hack.
offers contain an x-only pubkey: to route to them to need to know the
02 vs 03 prefix.  If they're in the gossmap it's easy, but if they're
a directly-connected peer it's harder.  We used to have
sendonionmessage tweak the key if it found a peer with the matching
key, but this was always a hack.

It turns out that we try to connect to the node anyway, which is
a noop if it's already connected.  So try connecting to the other
parity if the first one fails.

Also, this registers when we fail to connect, and returns an error
rather than waiting for timeout.
