Rusty Russell e8d2176e6b pytest: protect against bad gossip messages from mining confirms too fast.
If we fund a channel between two nodes, then mine all the blocks to
announce it, any other nodes may see the announcement before the
blocks, causing CI to complain about "bad gossip":

```

Add a new helper for this case, and use it where there are more than 2 nodes.

Cleans up test_routing_gossip and a few other places which did this manually.

Rusty Russell f7f9f35f2a pytest: remove flake in test_upgrade_statickey_onchaind
We were relying on the fee update to create an additional tx.  That's
ugly; do an actual payment and make sure we definitely complete a new
tx by waiting for that *then* both revoke_and_ack.

(Without this, we could get a unilateral close instead of a penalty).

Rusty Russell 4dc72dd829 dualopend: tell lightningd about new channel as soon as it's locked in.

2022-02-08 11:15:52 +10:30
Rusty Russell 88a4502a51 channeld: pause before sending initial channel_update.
The last change exposed a race: the peer sends funding_locked
then immediately sends an update_channel.  channeld used to process
the funding_locked from the peer, tell gossipd about the new
channel, then finally forward the channel_update.

We can have the channel_update hit gossipd before we've told it about
the channel.  It ignores the channel_update for the currently-unknown
channel: we get a 'bad gossip' message, but the immediate symptom
is a timeout in tests/test_closing.py::test_onchain_multihtlc_their_unilateral:

```
node_factory = <pyln.testing.utils.NodeFactory object at 0x7fdf93f42190>
bitcoind = <pyln.testing.utils.BitcoinD object at 0x7fdf940b99d0>

        """Node pushes a channel onchain with multiple HTLCs with same payment_hash """
>       h, nodes = setup_multihtlc_test(node_factory, bitcoind)

    wait_for(lambda: self.is_channel_active(chanid))
```

Note that we are usually much faster to send between subds than we are
between peers, but during CI this is common, as we're all running on
the same machine.

Sebastian Falbesoner 8309a049eb db: enable SQLite extended result codes
With this change, we get more fine-grained error messages if something
goes wrong in the course of communicating with the SQLite database. To
pick some random examples, the error codes SQLITE_IOERR_NOMEM,
SQLITE_IOERR_CORRUPTFS or SQLITE_IOERR_FSYNC are way more specific
than just a plain SQLITE_IOERR, and the corresponding error messages
generated by sqlite3_errstr() will hence give a better hint to the
user (or also to the developers, if an error report is sent) what the
cause for a failure is.
