Rusty Russell 50eccb6a12 connectd: handle pings and pongs.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Changed: JSON_RPC: `ping` now works with connected peers, even without a channel.

Rusty Russell 0ac5c4f8df pytest: ignore pings when doing query_gossip.
Next patch starts a timeout ping, which can interfere with results.

In theory, we should reply, but in practice (so far!) we seem to get enough
time that it doesn't hang up on us.

Rusty Russell bba468a51c connectd: temporarily have two fds to gossipd.
We want to stream gossip through this, but currently connectd treats the
fd as synchronous.  While we work on getting rid of that, it's easiest to
have two fds.

Rusty Russell 4dc72dd829 dualopend: tell lightningd about new channel as soon as it's locked in.
Once we send funding_locked, gossipd could start seeing channel_updates
from the peer (which get sent so we can use the channel in routehints
even before it's announcable).

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 """

    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.

Rusty Russell a8bed542f7 lightningd: start gossipd after channels are loaded.
This is in preparation for gossipd feeding us the latest channel_updates,
rather than having lightningd and channeld query gossipd when it wants
to send an onion error with an update included.

This means gossipd will start telling us the updates, so we need the
channels loaded first.

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.
