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.")

Mainly, field name changes.

Changelog-EXPERIMENTAL: Protocol: Support for forwarding blinded payments (as per latest draft)
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.

Changelog-EXPERIMENTAL: offers: complete rework of spec from other teams (yay!) breaks previous compatibility (boo!)
In particular, this changes the name of a field in invoice_request:
`payer_signature` becomes simply `signature`. So we allow both for
now, and send the old one unless deprecated_apis is disabled.

We keep the now-removed chains field, and in deprecated mode, we set it.

Changelog-EXPERIMENTAL: bolt12: `chains` in invoice_request and invoice is deprecated, `chain` is used instead.
Main changes are:
1. Uses point32 instead of pubkey32.
2. Uses issuer instead of vendor.
3. Uses byte instead of u8.
4. blinded_path num_hops is now a byte, not u16 (we don't use that yet!).

Changelog-EXPERIMENTAL: bolt12: `vendor` is deprecated: the field is now called `issuer`.
@shesek points out that we called this field created_at in bolt11 decode,
which makes more sense anyway.
Changelog-EXPERIMENTAL: bolt12 decode `timestamp` field deprecated in favor of new name `created_at`.

We don't support it (yet), but update the spec to include it.
We include the previous field (recurrence_signature) as a shim for the
moment, for compat with existing nodes. It's ugly, but next release
we'll stop *sending* it, then finally we'll stop accepting it!

For some reason, an old version was checked in. We don't currently
use it (since bolt12 support depends on EXPERIMENTAL_FEATURES, which
uses bolt12_exp_wire.csv, which is generated and not checked in).
