We don't need to log msgs from subds, but we do our own, and we weren't.
1. Rename queue_peer_msg to inject_peer_msg for clarity, make it do logging
2. In the one place where we're relaying, call msg_queue() directly.

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.

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.

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).
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
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>

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.

We want it to keep the latest, so it can make its own error msgs without
asking us. This installs (but does not use!) the message handler.

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.

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.
Changelog-None
Firstly, we were not adding the extra fee output on our dummy tx,
because the fee amount was 0. We probably should always do this, even
if it's 0.
Secondly, there are 6 witnesses, not 1, for elements txs.

This fixes lightningd's chronic weight underestimate.

Changelog-Fixed: closingd: more accurate weight estimation helps mutual closing near min/max feerates.
And in particular, fix onchaind grinding code which used the
actual number of inputs and outputs (which already includes the
fee output); that breaks with the next patch which fixes other
calculations.

The blockheight is zero though, since these aren't included in a block
yet.
We also don't issue an 'external' deposit event if we can tell that the
address you're sending to actually belongs to our wallet (we'll issue a
deposit event when it gets included in a block)
If a coin move concerns an external account, it's really useful to know
which 'internal' account initiated the transfer.
We're about to add a notification for withdrawals, so we can use this to
track wallet pushes to outside addresses
Changelog-Added: JSONRPC: `coin_movement` to 'external' accounts now include an 'originating_account' field

If l2's channeld gets killed (due to reconnect) before it tells
lightningd it got the revoke_and_ack it will need a retransmission
*again*.
This makes the test more robust, and does more checks too.

lightningd would race with the subd destructor to do the waitpid(),
resulting in UNUSUAL log messages, but also us missing if a plugin
was killed via a signal.

This was put in late 2019, and @t-bast says Eclair doesn't ignore their
errors and has had no issues.
It also conflicts with https://github.com/lightning/bolts/pull/932

This seems to trigger now, especially on PostgresQL (maybe it's faster
to process blocks?).
e.g. test_closing_simple() hangs in close(), because the close is unilateral
because the HTLC timed out, so it's waiting for a block (other lines removed):
