niftynei d284b98911 notify: `channel_state_changed` now receives notice when channel opens
Previously we wouldn't notify when a channel moves into state
"CHANNELD_AWAITING_LOCKIN", as this is the original state (so there's
no movement btw states). This meant that it's impossible to track when a
channel's commitment txs have been exchanged and we're waiting for
onchain confirmation.

It's useful to have notice of this initialization though, all in one
place so that the `channel_state_changed` notification can successfully
track the entire lifecycle of a channel, from inception to close.

Note that for v2 "dual-funded" channels, we already notify at the same place, at
"DUALOPEND_AWAITING_LOCKIN" (the initial state for a dualopend channel
is "DUALOPEND_OPEN_INIT" -- this is the only state we don't get notified
at now...)

Changelog-Added: Plugins: `channel_state_changed` now triggers for a v1 channel's initial "CHANNELD_AWAITING_LOCKIN" state transition (from prior state "unknown")

Rusty Russell 06e1e119aa pytest: fix test_gossip_no_empty_announcements flake.
This is a side-effect of fixing aging: sometimes, we age our
rcvd_filter cache too fast, and thus re-xmit.  This breaks
our test, since it used dev-disconnect on the channel_announce,
but that closes to l3, not l1!

```

Rusty Russell 7dd8e27862 connectd: don't insist on ping replies when other traffic is flowing.
Got complaints about us hanging up on some nodes because they don't respond
to pings in a timely manner (e.g. ACINQ?), but that turned out to be something
else.

Nonetheless, we've had reports in the past of LND badly prioritizing gossip

Because we expire cache every flush, in DEVELOPER mode that can happen in

this can mean we actually forget we received it from the peer.

Easiest fix is to run this test in non-DEVELOPER mode.

Even though we generally wait until a node has seen the gossip,
that doesn't mean that connectd has processed it!  This means when

So we set the OPT_GOSSIP_QUERIES bit, which means don't send until we
ask.  But now it sends us WIRE_QUERY_CHANNEL_RANGE, so everyone needs
to filter that out.

Rusty Russell 6221ac621d pytest: fix timeout in test_option_types
We were waiting for the start to timeout waiting for the "public key"
message.  Instead, start manually.

Before, this took (with TIMEOUT=30) 97 seconds, after 8 seconds.

Rusty Russell d2952576cd pyln-testing: restore proper streaming behaviour for lightningd.
Get it to log direct to stdout, so we see what's happening *as it
happens* rather than as we read it.  We could restore the thread we
were using before, but that added more problems than it solved.

This means that we need the hsm password prompts in the log though.

Rusty Russell a0e0dbf229 pyln-testing: use files for stdout and stderr, not threads.
Some flakes are caused by weird races in this code.  Plus, if we
get things to write straight to files, we might see things in
there on post-mortem which happen after the python runner exits.

It's a bit less efficient, but much simpler.  Let's see if it helps!

Some tests need a rework now, since we don't get a failure (except
eventual timeout), but they're simpler.

Rusty Russell 517828adb2 lightningd: don't print nasty message when onchaind fails partially-failed HTLC
1. We set an outgoing htlc's `failonion` when we get a commitment_signed.
2. We don't transfer it to the corresponding incoming HTLC until we send
   commitment_signed and receive revoke_and_ack (meaning, outgoing htlc is
   completely dead).
3. If between these steps we go onchain, onchaind (after 3 blocks) tells us
   to fail the HTLC.
4. hout->failonion is set, but hout->hin has not been failed yet.  We
   do a sanity check and print a nasty message, and fail it with
   WIRE_PERMANENT_CHANNEL_FAILURE instead of relaying the error.

So handle this case explicitly.

remove that and simply always query l4.

Rusty Russell aefcea44a3 pytest: fix flake in test_gossip_timestamp_filter
We didn't get the second channel_announcement in the filter:
```

        msgs = l4.query_gossip('gossip_timestamp_filter',
                               genesis_blockhash,

        # 0x0100 = channel_announcement
        # 0x0102 = channel_update
        # (Node announcement may have any timestamp)

Rusty Russell 575b94c1ef pytest: Remove all trace of python's "flaky" module.
Over time, it has cost us more developer cycles than it has gained.
It has hidden intermittant bugs, and allowed cruft to accumulate:
when we eventually tried to figure out what was going wrong, the
actual change which caused it was now stale and forgotten.

This was a particular bane during the connectd rewrite, and I

   xxx_msat.
2. json_add_amount_sats_deprecated: We were using it wrong, so deprecate
   the old field and create a new one which does end in _msat.
3. json_add_sats: we were using it to hand sats as a JSON parameter to an
   interface, where "XXXsat".

Rusty Russell 2526e804f7 doc: big BOLT update to incorporate warnings language.
We do this (send warnings) in almost all cases anyway, so mainly this
is a textual update, but there are some changes:

1. Send ERROR not WARNING if they send a malformed commitment secret.
2. Send WARNING not ERROR if they get the shutdown_scriptpubkey wrong (vs upfront)
3. Send WARNING not ERROR if they send a bad shutdown_scriptpubkey (e.g. p2pkh in future)
4. Rename some vars 'err' to 'warn' to make it clear we send a warning.

This means test_option_upfront_shutdown_script can be made reliable, too,
and it now warns and doesn't automatically close channel.

Rusty Russell 9f06a59e3c shutdown: don't allow shutdown to p2pkh or p2sh addresses for anchor outputs.
This doesn't have an effect now (except in experimental mode), but it
will when we support anchors.  So we deprecate the use of those in the
close command too.

For experimental mode we have to avoid using p2pkh; adapt that test.
