48259afb70 lightningd: always broadcast our own gossip when it changes.
When a peer connects, we always send all our own gossip (even if they
had set the timestamp filters to filter it out).  But we weren't
forcing it out to them when it changed, so this logic only applied to
unstable or frequently-restarting nodes.

So now, we tell all the peers whenever we tell gossipd about our new
gossip.

Fixes: #7276

Changelog-Changed: Protocol: We now send current peers our changed gossip (even if they set timestamp_filter otherwise), not just on reconnect.

c68204a32a lightningd: store our id as a struct pubkey as well as struct node_id.
We convert it in various places, so do that only once.  Also, the name
"id" is a little curt.

9450d46db1 bitcoin/short_channel_id: pass by copy everywhere.
It's a u64, we should pass by copy.  This is a big sweeping change,
but mainly mechanical (change one, compile, fix breakage, repeat).

37d22f9141 global: change all type_to_string to fmt_X.
This has the benefit of being shorter, as well as more reliable (you
will get a link error if we can't print it, not a runtime one!).

d8c06dccac global: expose all fmt_X functions for direct use, make uniform.
We have various functions to convert to a string, rename them all so we can
count on fmt_X being the formatter for struct X, and make them all return
`char *`.

Sometimes they existed but were private, sometimes they had a
different name.  Most take a pointer, but simple types pass by copy:
short_channel_id, amount_msat and amount_sat.

The following public functions changed:
1. psbt_to_b64 -> fmt_wally_psbt.
2. pubkey_to_hexstr -> fmt_pubkey.
3. short_channel_id_to_str -> fmt_short_channel_id (scid by copy now!)
4. fmt_signature -> fmt_secp256k1_ecdsa_signature
5. fmt_amount_sat/fmt_amount_msat pass copy not pointer, return non-const char *.
6. node_id_to_hexstr -> fmt_node_id

23460eb89d lightnignd: Fix another assert crash.
If we accept a channel_update in state "NEED_SIGS" we should not set
refresh timer: we're simply holding it for the moment we get to that state
(which will happen as we mine the block).

d716e6db73 lightningd: don't force state if gossipd gives us an unexpected channel_update.
This was triggered by the recover plugin tests (not yet merged!) and causes a crash
because we don't have signatures yet.  It can only happen if we lost our database,
but at least don't crash!

8f7f76f8c6 gossipd: don't validate UTXOs on our own channels.
It's an unnecessary round-trip, and can cause us to complain in CI, in
the case where the channel has been closed by the time we ask.

1f9e9777f0 lightningd: don't generate node_announcements with identical timestamps.
This caused a flake in test_gossip_lease_rates, since the peer would ignore
the node_announcement due to duplicate timestamps!

95bc730894 lightningd: set last_stable_connection 1 minute after channel reestablished.
This is a nice reflection of channel stability: in particular, worse case
ping time is 45 seconds, so we should have had some traffic.

81a280d8a3 lightningd: expose reestablished field.
This is useful to see if we've really made progress, or just bounced
off the peer (e.g. it doesn't know the channel, or we have fallen
behind somehow).

Changelog-Added: JSON-RPC: `listpeerchannels` new field `reestablished` set once we've exchanged `channel_reestablish` messages.

40d063cda4 channeld: notify lightningd once we've exchanged reestablish messages.
In particular, we were sending `announcement_signatures` before
`channel_reestablish`; we allow this because LND used to do it, but
it's not spec compliant.
