No idea why we were iterating over the list of stubs and then passing
in the index instead of a pointer to the stub directly.

This wires in the loading of `struct htlc_stub`s on-demand when
starting `onchaind` so that we don't need to keep them in memory.

We'd like to not keep them in memory and retrieve them on-demand when
`onchaind` is launched. This uses the `channel_htlcs` table as backing
but only fetches the minimal necessary information.

Now that we have HTLC persistence we'd also like to test it. This
kills the second node in the middle of an HTLC, it'll recover and
finish the flow.

This makes executing a query/command a two step process, but allows us
to use the native binding and avoid having to build queries as SQL
strings. Two major advantages are that we are no longer vulnerable to
SQL injections and that we do not have to hex-encode binary fields
like private keys, hashes, and routing onions, halving the storage
requirements for those.

So far we were tracking the status by including it either in the paid
or the unpaid list. This refactor makes the state explicit, which
matches the planned DB schema much better.

This was causing me some trouble by making it look like the last query
failed, when it really was an old one. No need to drag failures around
for longer than needed.

This is a necessary evil since at the time we load `struct htlc_out`
associated with a channel we might not have loaded the `struct
htlc_in` that it depends on, so we defer the rewiring until we have
loaded all HTLCs for all channels. At that point rewiring MUST work,
otherwise we report a failure.

While loading HTLCs from the database we might not yet have all the
incoming HTLCs loaded when loading a dependent htlc_out. So we defer
the wiring of the HTLCs until we are sure we have them loaded.
This is also the first step towards keeping that association only in
the database, since otherwise we cannot selectively load channels from
DB.

Also added a small warning to one of the used enums not to reorder or
insert values. They'd break the update path.

Especially when testing we might want to disable the automatic
reconnection logic in order not to masquerade bugs that disappear when
reconnecting.

This broke somewhere in the recent changes, because we override
TailalbleProc stop(). Break out log extractor.

We don't hit this in testing, since we wait for startup already. Hacking
tests to avoid that, I tested this code by hand.

Moved the flagging for allowed failures into the factory getter, and
renamed into `may_fail`. Also stopped the teardown of a node from
throwing an exception if we are allowed to exit non-cleanly.

A failed returncode check could result in the cleanup for other
lightningds to be skipped. Now make sure to cleanup all and then
rethrow an exception that contains all returncodes.

We used to simply kill the daemon, which in some cases could result in
half-written crashlogs and similar artifacts such as half-completed
RPC calls. Now we ask lightningd to stop nicely, give it some time and
only then kill it. We also return the returncode of the daemon.
