As suggested in https://github.com/lightning/bolts/pull/1092.
We still support channels opened without it, but you can no longer open new ones without it.

Changelog-Changed: Protocol: `option_gossip_queries` is now required (advertized by all but 16 nodes)
Since the class interacts with int very well now, we don't have to
make explicit accesses, so it's easy to write code which works with
Millisatoshi or int.
Also, don't access rpc.decoder in one test, it's unnecessary.

This is redundant if it's a public channel, but vital if it's not. Publishing unconditionally makes
it easier for gossmap: we create a local modification all the time, even if redundant (and we can
have the actual capacity ceiling accurate in this case, since we know it for local channels).

Changelog-Added: JSON-RPC: `listpeerchannels` now shows gossip update contents (even if channel unannounced).

Changelog-Fixed: JSON-RPC: Plugin notification `msat` fields in `invoice_payment` and `invoice_created` hooks now a number, not a string with "msat" suffix.
Changelog-Fixed: JSON-RPC: Plugin hook `payment` `msat` field is now a number, not a string with "msat" suffix.
Here, we split up what was "commit_received" into two phases:
- commit-ready, where we're about to send our commitment tx to
peer
- commit-received, when we've gotten the commitment tx from our
peer
This lets us do the right thing (as far as the spec is concerned) with
returning the correct 'next_funding_txid' on reconnect (later commits).

Changelog-Changed: Config: `large-channels` is now the default, wumbology for all.
We remove it from the pending_requests strmap before calling it,
so it doesn't get called again by destroy_plugin.

Now the internal code will generate a "PLUGIN_TERMINATED" response
when the plugin dies, we can handle it in plugin_hook.
But we can also simplify it by turning the snapshot of hooks into
a simple array: this means we are robust against any combination of plugins
exiting at any time.
Note: this reveals an issue with test_rpc_command_hook where we run
the request hook again (unexpectedly), so we disable that for the next
patch.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
We had special code to fail a forwarded request, but not for an
internally-generated request. Instead, we should pretend the (dead)
plugin responded with a PLUGIN_TERMINATED error, and handle the
request through the normal paths.
This breaks the case where a plugin crashes (or stops itself) in a
hook, so we handle that next.

The latter is used when we're put in the db, the former is the uncommitted state.
Currently dbid == 0 is used in addition to the state, which is unwieldy.

Changelog-Experimental: JSON-RPC: added new dual-funding state `DUALOPEND_OPEN_COMMITTED`
And require --developer to use them.
Also refuse redirection to deprecated APIs if deprecated APIs are disabled!

We were allowed to, but the spec removed that. So we handle warnings
differently from errors now.
This also means the LND "internal error" workaround is done in
lightningd (we still disconnect, but we don't want to close channel).
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Changed: Protocol: we no longer disconnect every time we receive a warning message.
The code to workaround the intermittant error didn't work,
and we finally hit it again:
```
# If reject happens fast enough, connect fails with "disconnected
# during connection"
try:
l3.connect(l1)
except RpcError as err:
> assert "disconnected during connection" in err.error
E assert 'disconnected during connection' in {'code': 402, 'message': 'disconnected during connection'}
E + where {'code': 402, 'message': 'disconnected during connection'} = RpcError("RPC call failed: method: connect, payload: {'id': '0266e4598d1d3c415f572a8488830b60f7e744ed9235eb0b1ba93283b315c03518', 'host': '127.0.0.1', 'port': 41865}, error: {'code': 402, 'message': 'disconnected during connection'}").error

```
l3.rpc.setconfig('autoclean-cycle', 10)
# First it expires.
> wait_for(lambda: only_one(l3.rpc.listinvoices('inv1')['invoices'])['status'] == 'expired')
```
If we're slow enough, the invoice is cleaned before we see it expire!

Changelog-Fixed: Plugins: we clean up properly if a plugin fails to start, and we don't kill all processes if it's from `plugin startdir`.
Update the lightningd <-> channeld interface with lots of new commands to needed to facilitate spicing.
Implement the channeld splicing protocol leveraging the interactivetx protocol.
Implement lightningd’s channel_control to support channeld in its splicing efforts.
Changelog-Added: Added the features to enable splicing & resizing of active channels.
Clean these up: they were debug logs, but we want to pass this information
back for self-payments.
Also fixes "Attept" typo which altered tests!

This means (temporarily) that blacklisting won't work (fix later), and
means that old-style (commando.py) master-secret-override doesn't work.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Removed: Plugins: `commando` no longer allows datastore ['commando', 'secret'] to override master secret (re-issue runes if you were using that!).
We used to activate on the first rune creation, but we're no longer in charge
of runes, so we can't make that call.

If you miss a wait event, you can catch up by doing listinvoices and
getting the max of these fields. It's also a good debugging clue.

These tests make assumptions about the presplitter behavior which
we'll remove in the next commit. We remove them here so we don't cause
temporary breaks in the git history.
We fixed the others. There are no fields, but this keeps it consistent.
