Rusty Russell 9a575a98a0 gossipd: simplify large reply code.
We used to create the entire reply, the if it was too big, split in
half and retry.

Now that the main network is larger, this always happens with a full
request, which is inefficient.

Instead, produce a reply assuming no compression, then compress as a
bonus.  This is simpler and more efficient, at cost of sending more
packets.

I also renamed an internal dev var to make it clearer.

Rusty Russell 83aea6b2bb gossip_store: make private channels more similar to channel_announcement
Instead of a boutique message, use a "real" channel_announcement for
private channels (with fake sigs and pubkeys).  This makes it far
easier for gossmap to handle local channels.

Backwards compatible update, since we update old stores.

We also fix devtools/dump-gossipstore to know about the tombstone markers.

Since we increment our channel_announce count for local channels now,
the stats in the tests changed too.

Christian Decker 05934724dd pytest: Don't start 3 nodes in test_gossip_ratelimit
We really are just interested in their on-chain footprint, so actually
starting the nodes is pointless overhead, and caused a lot of flakyness due to
the output ordering sometimes not matching up. We now just use the `bitcoind`
API to fund, sign and send a raw transaction that matches the stashed gossip
messages.

Rusty Russell 74e960c20b pytest: increase channel sizes so they reach min capacity with option_anchor_outputs
With a feerate of 7500perkw and subtracting 660 sats for anchors, a
20,000 sat channel has capacity about 9800 sat, below our default:

	You gave bad parameters: channel capacity with funding 20000sat, reserves 546sat/546sat, max_htlc_value_in_flight_msat is 18446744073709551615msat, channel capacity is 9818sat, which is below 10000000msat

So bump channel amounts.

Rusty Russell fde353ab00 pytest: use get_nodes more widely.
I started replacing all get_node() calls, but got bored, so then just did the
tests which call get_node() 3 times or more.

Ends up not making a measurable speed difference, but it does make some
things neater and more standard.

Time before (non-valgrind):
	393 sec (had 3 failures?)
Time after (non-valgrind):

common/features: only support a single feature bitset.
This is mainly an internal-only change, especially since we don't
offer any globalfeatures.

However, LND (as of next release) will offer global features, and also
expect option_static_remotekey to be a *global* feature.  So we send
our (merged) feature bitset as both global and local in init, and fold
those bitsets together when we get an init msg.

Rusty Russell 147eaced2e developer: consolidiate gossip timing options into one --dev-fast-gossip.
It's generally clearer to have simple hardcoded numbers with an
#if DEVELOPER around it, than apparent variables which aren't, really.

Interestingly, our pruning test was always kinda broken: we have to pass
two cycles, since l2 will refresh the channel once to avoid pruning.

Do the more obvious thing, and cut the network in half and check that
l1 and l3 time out.

Rusty Russell a92ead48bf gossipd: ignore redundant channel_update and node_announcement.
If you send a message which simply changes timestamp and signature, we
drop it.  You shouldn't be doing that, and the door to ignoring them
was opened by by option_gossip_query_ex, which would allow clients to
ignore updates with the same checksum.

This is more aggressive at reducing spam messages, but we allow refreshes
(to be conservative, we allow them even when 1/2 of the way through the
refresh period).

I dropped the now-unnecessary sleep from test_gossip_pruning, too.
