We've been sending them errors for invalid replies; instead, this works
around it.
Changelog-Added: Workaround LND's reply_channel_range issues instead of sending error.

I thought LND had a bug, but turns out it doesn't like out-of-order
short_channel_ids: in fact, the spec says they have to be in order!
This means we use uintmap instead of a htable for unknown_scids and
stale_scids so they're nicely ordered.
But our nodes-missing-announcements probe is harder since they can
also contain duplicates: we switch that to iterate through channels
rather than nodes.

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.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
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.
