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.

See: https://github.com/lightningnetwork/lightning-rfc/pull/826

Changelog-Changed: Protocol: we use `sync_complete` for gossip range query replies, with detection for older spec nodes.

a7c5a1f1d2 lightningd: implement receiving warnings.
This takes from the draft spec at https://github.com/lightningnetwork/lightning-rfc/pull/834

Note that if this draft does not get included, the peer will simply
ignore the warning message (we always close the connection afterwards
anyway).

Changelog-Added: Protocol: we now report the new (draft) warning message.

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.

9d57612415 gossipd, channeld: handle onion messages in gossipd so we don't need a channel.

Trying to rework the TLV streams to have a more homogenous interface to work

is going to be used by the wire code generator to generate the specific
accessors, but it's enough so we can manipulate TLV streams in the onion and

because it was actually the same format.
