c57a5a0a06 gossipd: downgrade broken message that can actually happen.
I saw this in test_bech32_funding: the peer disconnected and told gossipd before lightningd
relayed a local_channel_announcement from the subd:

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)

301acc9556 gossipd: only use IP discovery if no addresses are announced
This will only add the discovered `remote_addr` IPs if no other
addresses would be announced. Meaning whenever a public address was
found by autobind or an address was specified via commandline or config,
IP discovery will be disabled.

Addresses: #5305

Note from the author: We could/should also enable IP discovery when we only
have a TOR address (but without --always-use-proxy ofc). This will give
nodes an option to have a bootstrap way to be reached until IP discovery
can do the job in a more stable way.

Changelog-Changed: Only use IP discovery as fallback when no addresses would be announced

ddf8fbdb5d gossipd: fix crash from gossip_store v10 changes
routing.c fixed to properly remove rate-limited gossip_store entries
when channels are closed. This caused gossipd to crash on a subsequent
gossip_store_load. Also corrects an overzealous limit of one gossip_store
entry per message (should now allow one broadcastable and one
rate-limited). Addresses issues 5387, 5395.

11de721ba9 gossipd: fix gossmap race.
When upgrading a channel from private to public, we would delete the
private channel then add the public one.  However, this is visible in
the gossmap!  In particular, the node may be removed from the gossmap
and then re-added, so it may temporarily vanish!

I was seeing an occasional assertion inside node_factory.line_graph:

```
@pytest.mark.developer

        """We re-announce, even when remote node doesn't send its announcement_signatures on reconnect.

0b7897302e common/gossip_store: optimize case where entries are filtered out.
@whitslack complained of large CPU usage by connectd at startup;
I ran perf record on connectd on my machine (which sees a little spike, only)
and I see the cost of reading and discarding the entries:

```
-   95.52%     5.24%  lightning_conne  lightning_connectd  [.] gossip_store_next
   - 90.28% gossip_store_next
      + 40.27% tal_alloc_arr_
      + 22.78% tal_free
      + 11.74% crc32c
      + 9.32% fromwire_peektype
      + 4.10% __libc_pread64 (inlined)
        1.70% be32_to_cpu
```

Much of this is caused by the search for our own gossip: keeping this separately
would be even better, but this fix is minimal.

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".

2526e804f7 doc: big BOLT update to incorporate warnings language.
We do this (send warnings) in almost all cases anyway, so mainly this
is a textual update, but there are some changes:

1. Send ERROR not WARNING if they send a malformed commitment secret.
2. Send WARNING not ERROR if they get the shutdown_scriptpubkey wrong (vs upfront)
3. Send WARNING not ERROR if they send a bad shutdown_scriptpubkey (e.g. p2pkh in future)
4. Rename some vars 'err' to 'warn' to make it clear we send a warning.

This means test_option_upfront_shutdown_script can be made reliable, too,
and it now warns and doesn't automatically close channel.

d991f13516 gossipd: make sure we set the urgent bit if we move our own node_announcement.
node_announcement has to follow at least one channel_announcement.
When channels close, if this isn't the case, we remove the old
node_announcement and put it at the end of the gossip_store.

But we lose the "send even if they don't want it" bit in the case it's
our own node_announceent, so keep it.

This only happens if you don't change your node configuration at all
since you opened your first channel, but still worth fixing.

We expose the force_node_announce_rexmit() for later use.

3121cebf4c gossipd: don't hand out fds.
Gossipd now simply gets told by channeld when peers arrive or leave.
(it only needs to know for the seeker).

We also no longer strip the type off: everyone handles both forms, and
Eclair doesn't strip (and it's easier!).
