401f1debc5 common: clean up json routine locations.
We have them split over common/param.c, common/json.c,
common/json_helpers.c, common/json_tok.c and common/json_stream.c.

Change that to:
* common/json_parse (all the json_to_xxx routines)
* common/json_parse_simple (simplest the json parsing routines, for cli too)
* common/json_stream (all the json_add_xxx routines)
* common/json_param (all the param and param_xxx routines)

9dc794dba8 gossipd: make use of new ratelimit bit in gossip_store length mask
routing.c now flags rate-limited gossip as it enters the gossip_store but
makes use of it in updating the routing graph. Flagged gossip is not
rebroadcast to gossip peers.

Changelog-Changed: gossipd: now accepts spam gossip, but squelches it for
peers.

36a2491a89 json: fix up msat amounts in non-_msat fields.
We had json_add_amount_msat_only(), which was designed to be used to
print out msat fields, if we had sats.

However, we misused it, so split it into the three different cases:
1. json_add_amount_sat_msat: We are using it correctly, with a field called
   xxx_msat.
2. json_add_amount_sats_deprecated: We were using it wrong, so deprecate
   the old field and create a new one which does end in _msat.
3. json_add_sats: we were using it to hand sats as a JSON parameter to an
   interface, where "XXXsat".

67fdc6f8ad gossipd: send updated node_annoucement remote_addr
This is the cheapest algo I came up with that simply checks that the
same `remote_addr` has been report by two different peers. Can be
improved in many ways:

 - Check by connecting to a radonm peers in the network
 - Check for more than two confirmations or a certain fraction
 - ...

Changelog-Added: Send updated node_annoucement when two peers report the same remote_addr.

e841e69b1b channeld: send channel updates and announcements via lightningd.

4ffda340d3 check: make sure all files outside contrib/ include "config.h" first.
And turn "" includes into full-path (which makes it easier to put
config.h first, and finds some cases check-includes.sh missed
previously).

config.h sets _GNU_SOURCE which really needs to be done before any
'#includes': we mainly got away with it with glibc, but other platforms
like Alpine may have stricter requirements.

cb22015b2a common/channel_type: wrapper for generated 'struct channel_type'.
We make it a first-class citizen internally, even though we won't use
it over the wire (at least, non-experimental builds).  This scheme
follows the latest draft, in which features are flagged compulsory.

We also add several helper functions.

Since uses the *even* bits (as per latest spec), not the *odd* bits,
we have some other fixups.

0d4f014021 gossip_store: create end marker for EOF.
This is better than using the previous "keep statting the file" approach,
since we can also tell you how long the replacement is, to avoid a
gratitous load.

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.
