We eliminate the "need peer" states and instead check if the
random_peer_softref has been cleared.
We can also unify our restart handlers for all these cases; even the
probe_scids case, by giving gossip credit for the scids as they come
in (at a discount, since scids are 8 bytes vs the ~200 bytes for
normal gossip messages).

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.

This encoding scheme is no longer just used for short_channel_ids, so make
the names more generic.

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.
