If you do update-mocks in a dirty tree, the recursive make that it
uses will try to rebuild things! Suppress that.

We set the timeout on first HTLC, but didn't clear it if that HTLC failed.
It's saner to have a per-HTLC timeout (since that's what it is!) and
also our timer infra is specially coded to scale approximately infinitely so
trying to optimize this is vastly premature.

Changelog-Fixed: Protocol: We would sometimes gratuitously disconnect 30 seconds after an HTLC failed.
If l2 didn't get FUNDING_LOCKED from l1 before it disconnected, it
won't be in state CHANNELD_NORMAL: it will be in DUALOPEND_AWAITING_LOCKIN.

1. We don't need to check for NULL before tal_count(NULL).
2. Use of json_for_each_arr iterator is probably better.
3. Weird indent fixed.

This would flake fairly regularly, what we really care about is
asserting that the l2 node is in CHANNELD_NORMAL state, while the l1
node hasn't progressed that far yet.
Peer sends funding locked, we tell lightningd who saves it to disk.
Then we restart/reconnect and they retransmit funding_locked. We were
re-notifying lightningd about their lock-in, which was crashing/breaking
things. Instead, we ignore duplicate lock-in messages from the peer.
lightningd-1: 2021-05-11T18:00:12.844Z **BROKEN** 022d223620a359a47ff7f7ac447c85c46c923da53389221a0054c11c1e3ca31d59-chan#1: Internal error DUALOPEND_AWAITING_LOCKIN: channel_got_funding_locked twice
Trying to put all the disconnect logic into the same path was a dumb
idea. If you asked to reconnect but passed in an 'unsaved' channel, we
would not call the 'reconnect' code.
Instead, we make a differentiation between "unsaved" channels
(ones that we haven't received commitment tx for) and handle the
disconnect for these separate from where we want to do a reconnect.
We were freeing the payload, which is then subsequently freed by the
plugin_hook caller. Whoops.
Now we pass through to the callback function and just clean up neatly.

Users are more upset recently with the cost of unilateral closes
than they are the risk of being cheated. While we complete our
anchor implementation so we can use low fees there, let's
get less aggressive (we already have 34 or 18 blocks to close
in the worst case).
The changes are:
- Commit transactions were "2 CONSERVATIVE" now "6 ECONOMICAL".
- HTLC resolution txs were "3 CONSERVATIVE" now "6 ECONOMICAL".
- Penalty txs were "3 CONSERVATIVE" now "12 ECONOMICAL".
- Normal txs were "4 ECONOMICAL" now "12 ECONOMICAL".
There can be no perfect levels, but we have had understandable
complaints recently about how high our default fee levels are.
Changelog-Changed: Protocol: channel feerates reduced to bitcoind's "6 block ECONOMICAL" rate.

Fixes: #4494

Changelog-Added: config: New option `log-timestamps` allow disabling of timestamp prefix in logs.
I wante to hide it inside the library, but it is good to have a single
place to verify that the client was permitted to send a message we are
handling, so make it officially part of the interface by prefixing it.
