This makes init a two-stage, and causes some code hoisting.
And we can now send all the HTLCs in a single message, since we have
an 128MB limit and each HTLC is 37 bytes.
This breaks the onchaind stresstest, which uses canned internal messages.
It's time to finally delete that.

Changelog-Changed: db: removal of old HTLC information and vacuuming shrinks large lightningd.sqlite3 by a factor of 2-3.
And initialize max to current height max when htlcs are already dead.
Turns out (thanks CI!) that MAX() of multiple columns is GREATEST() in
Postgres. That's clearer (MAX is used elsewhere for single columns),
so translate on the sqlite3 side.

sendonionmessage can fail when sending a reply, either because
the reply had a bad first peer, or because it went offline. The
latter happens in CI, which is how I found this.
Also fixed typo "onio" -> "onion".

Changelog-Added: pay: Payment attempts are now grouped by the pay command that initiated them
Changelog-Fixed: pay: `listpays` returns payments orderd by their creation date
Changelog-Fixed: pay: `listpays` no longer groups attempts from multiple attempts to pay an invoice
This re-establishes the prior behavior where a `sendpay` or
`sendonion` that'd match a prior payment would cause the prior payment
to be deleted. While we no longer delete prior attempts we now avoid a
primary key collision by incrementing once. This helps us not having
to touch all existing tests, and likely avoids breaking other users
too.
One of the fundamental constraints of the payment groups idea is that
there may only ever be one group in flight at any point in time, so if
we find a group that is in flight, any new `sendpay` or `sendonion`
must match its `groupid`.
This was the main cause of the pay states flip-flopping, since we
reset the status on each attempt any final status is not really
final. Let's keep them around, and provide a stable history.
So far we've always been deferring the deletion, retry and early abort
logic to `sendonion` and `sendpay` which do not have the context to
decide if a call is legitimate or not (they were mostly based on
heuristics). By calling `listsendpays` for the invoice's
`payment_hash` we can identify what our `groupid` should be, but more
importantly we can also abort if another payment is pending or a prior
attempt has already succeeded.
When doing things like `waitsendpay` without specifying the `groupid`
we likely want to use the latest `groupid` we created, since that's
the one in flight. This adds a function to quickly retrieve that.
channeld may have sent a ping before shutdown, now closingd sees it.

We were really strict with the version check, requiring an exact
match. We now check that we are running at least with the version we
were compiled with (distro upgrades continue to work, and repro builds
are built off of an unupdated installation matching this minimum
requirement), and a major version match (since major versions can and
will introduce breaking changes).
Changelog-Fixed: sqlite3: Relaxed the version match requirements to be at least a minimum version and a major version match
If it reconnects by itself, it will get a warning message:

Changelog-Changed: Protocol: Send regular pings to detect dead connections (particularly for Tor).
We would sleep until the next timer, even if that's long past when we would

we will in the next patch, where we use continuous timers for pings.
