Rusty Russell 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)

rebroadcast to gossip peers.

Rusty Russell 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".

This attempted to make us re-xmit our own node_announcement at restart,

as nothing is connected, yet, this had no effect!

Michael Schmoock 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

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

Rusty Russell 0aad222c2d gossipd: rewrite update generation, remove local_chan.
local_chan was mainly around so we could "soft" disable channels (and
really disable them once we used the channel_update in an error
message).

Instead we introduce the idea of a "deferred_update": it's either
deferred indefinitely (a peer goes offline, if we need to send it in
an error we'll apply it immediatly), or simply delayed to avoid
spamming everyone.

The resulting rewrite is much clearer, IMHO.

Rusty Russell 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.

Rusty Russell 9c254c8387 gossipd: when we refresh channel, don't override pending updates.
We can have an update pending because it's too fast, but
refresh_local_channel is supposed to make sure we're up-to-date, so
force immediate application in that case.

Otherwise, we call update_local_channel at the bottom which frees the
pending update.  This can mean that we miss a change in fees, for example.
