3e8f575f9e dual-funding: convert to runtime flag, --experimental-dual-fund
You can now activate dual-funded channels using the
`--experimental-dual-fund` flag

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

31e3bdb42d df-spec: consolidate dual-funding patches, update feerate protocol
We consolidate to the latest/singular RFC patch for dual-funding, so
there's just a single patchfile for the change. Plus we move back to the
opener setting the desired feerate, the accepter merely declines to
participate if they disagree with the set rate.

ff069ff924 rbf: consolidate failure paths, use "warnings"
We move over to the new "warning" paradigm, instead of using
an "rbf_fail" message.

Every failure is either a warning or an error; on warnings we
hang up and reconnect later, effectively resetting the state.

9224d9a500 gossipd: use modern 'sync_complete' field.
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.

anyway).

06a54606a3 check-includes: allow redundant "config.h"
We should actually be including this (as it may define _GNU_SOURCE
etc) before any system headers.  But where we include <assert.h> we
often didn't, because check-includes would complain that the headers
included it too.

Weaken that check, and include config.h in C files before assert.h.
