This is better than using the previous "keep statting the file" approach,
since we can also tell you how long the replacement is, to avoid a
gratitous load.

This takes an extra 8 bytes per channel, but means we can go back and
get more information about them; this is implemented in
gossmap_chan_get_update_details() which is what listchannels will need.

Equivalent to gossipd/test/run-find_route.c and gossipd/test/run-find_route-specific.c
except they use gossmap.

This matters for:

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.
