It's not (yet?) compulsory to have the timestamps, but handing them around
together makes sense (a missing timestamp has the same effect as a zero
timestamp).

The main change here is that the previously-optional open/accept
fields and reestablish fields are now compulsory (everyone was
including them anyway). In fact, the open/accept is a TLV
because it was actually the same format.

Changelog-Removed: protocol: support for optioned form of reestablish messages now compulsory.

This asks peers to append the timestamps or checksums: if it has
gossip_query_ex support, it will, otherwise it's ignored.

If the peer supports `gossip_query_ex` we can use query_flags to simply
request the node_announcements when probing for nodes, rather than
getting everything. If a peer doesn't support `gossip_query_ex` then
it's harmless to add it.

The only real change is dump_gossip() used to call
maybe_create_next_scid_reply(), but now I've simply renamed
that to maybe_send_query_responses() and we call it directly.
