9685c1adaf lightningd: remove getsharedsecret.
This was introduced to allow creating a shared secret, but it's better to use
makesecret which creates unique secrets.  getsharedsecret being a generic ECDH
function allows the caller to initiate conversations as if it was us; this
is generally OK, since we don't allow untrusted API access, but the commando
plugin had to blacklist this for read-only runes explicitly.

Since @ZmnSCPxj never ended up using this after introducing it, simply
remove it.

769efe8d54 tests: massively speed up our wait for enormous feerates
We do smoothing, waiting for this to hit the target (50k+) was taking
longer than my TIMEOUT=15; here we increase the speed at which it hits
exit velocity, so to speak.

f2e7e9d919 coin-moves: only log htlc_timeout pair for penalty txs
We cleanup our output tracking for timeout txs when the peer's
htlc_timeout self-expiry is hit; we'd also log its spend if happen to
see it get spent.

This is a bit of a race as they can't spend it until the locktime is
available. Hence the flakiness in tests that expected the `htlc_timeout`
to *not* be spent.

Instead, we only log an external's `htlc_timeout` spend in the case
where we also immediately register another output to track for it (only
happens when said htlc is stealable)

Fixes #5405

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")

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

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

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.

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.

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.

We can hang up due to ping while waiting for channel to become active.
But we don't even need an active channel for this test, so simplify.

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.

We assumed that if the outgoing htlc has failed, we should have always
failed the incoming one.  This is not true, as this testcase demonstrates:
