Rusty Russell c34c055d82 Makefile: use completely separate spec-derived files for EXPERIMENTAL_FEATURES
This avoids overwriting the ones in git, and generally makes things neater.

We have convenience headers wire/peer_wire.h and wire/onion_wire.h to
avoid most #ifdefs: simply include those.

Rusty Russell 93d04d08d0 wire: update to latest version of the spec.
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.

For more details, see lightning-rfc/f068dd0d8dfa5ae75feedd99f269e23be4777381

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

Rusty Russell b0c9059602 tools/generate-wire: no more lonely messages!
When we have only a single member in a TLV (e.g. an optional u64),
wrapping it in a struct is awkward.  This changes it to directly
access those fields.

This is not only more elegant (60 fewer lines), it would also be
more cache friendly.  That's right: cache hot singles!

This reverts commit 7fd2f6db6d.

We want to set 'complete' to false in future if we don't know
everything!

Rusty Russell 9485919a81 queries: make sure scids are in order.
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.

Rusty Russell 869b5e40b5 gossipd: simplify seeker state machine.
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).

Rusty Russell 4dcb7df83e gossipd: add query_option_flags suport for asking query_channel_range.
This asks peers to append the timestamps or checksums: if it has

Rusty Russell 270368e50b gossipd: use gossip_query_ex to query only nodes when node probing.
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.
