We make it a first-class citizen internally, even though we won't use
it over the wire (at least, non-experimental builds). This scheme
follows the latest draft, in which features are flagged compulsory.
We also add several helper functions.
Since uses the *even* bits (as per latest spec), not the *odd* bits,
we have some other fixups.

We want to use this to handle the simple description for channel_type.
It also needs to handle variable-size types (just like subtypes).

It also gets rid of the requirement that close negotiation fee maximum
is the old commitment transaction. We still do that, however, to
avoid surprising old peers.

Using a 'feestep' is more restrictive than you'd want, instead we
enforce that the next feerate must be at least 1/64th more than the
last, but put no upper limit on it

Changelog-EXPERIMENTAL: Protocol: Replaces init_rbf's `fee_step` for RBF of v2 opens with `funding_feerate_perkw`, breaking change
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!

I wasn't regenerating these when I changed dependencies, because I was
configured with --enable-experimental-features. Putting them in
ALL_C_HEADERS and ALL_C_SOURCES means they'll be regenerated, even
though nothing depends on them.

Changelog-Changed: Config: `--experimental-dual-fund` runtime flag will enable dual-funded protocol on this node

We assume if they set this to 0 (which nobody did previously), they're
using it as a modern flag and use it to indicate when they're
finished. Otherwise, we count how many blocks they've sent and use
that to determine whether they've finished.

Changelog-Changed: Protocol: we use `sync_complete` for gossip range query replies, with detection for older spec nodes.
The fetchinvoice and offers plugins disable themselves if the option
isn't enabled (it's enabled by default on EXPERIMENTAL_FEATURES).

Changelog-Added: `experimental-offers` enables fetch, payment and creation of (early draft) offers.
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).

This is similar to the createinvoice API, except we don't need to save
invoice requests in the database. We may, however, have to look up
payment_key for recurring invoice requests, and sign the message with
the payment_key.

This is vital for calculating merkle trees; I previously used
towire+fromwire to get this!
Requires generation change so we can magic the ARRAY_SIZE var (the C

There's a lot of it, and it means we can't `make check-source` on
these files.
Also bring bolt quotes up-to-date.

We're going to make experimental versions of these completely separate files.
Also remove the dependency on the Makefile itself: it simply causes
unnecessary churn. We can always force-rebuild when we change a rule.
