This adds a new "chan_dying" message to the gossip_store, but since we
already changed the minor version in this PR, we don't bump it again.

Changelog-Added: Protocol: We now delay forgetting funding-spent channels for 12 blocks (as per latest BOLTs, to support splicing in future).
It's a bit more optimal, and tells gossipd exactly what height the
spend occurred at (with multiple blocks, it's not always the current
height!). It will need that next patch.

Changelog-Added: Protocol: We now set the `dont_forward` bit on private channel_update's message_flags (as per latest BOLTs).
We will now simply reject old-style ones as invalid. Turns out the
only trace we could find is a channel between two nodes unconnected to
the rest of the network.

Changelog-Changed: Protocol: We now require all channel_update messages include htlc_maximum_msat (as per latest BOLTs)
Many changes to gossmap (including the pending ones!) don't actually
concern readers, as long as they obey certain rules:
1. Ignore unknown messages.
2. Treat all 16 upper bits of length as flags, ignore unknown ones.
So now we split the version byte into MAJOR and MINOR, and you can
ignore MINOR changes.
We don't expose the internal version (for creating the map)
programmatically: you should really hardcode what major version you
understand!

If they really upgrade directly from 0.9.2, it will simply delete the
store and re-fetch it.
We still update from v9 (which could be v0.11), since it's a noop.

CI is really slow: it sees all three expire at once. But making the
timeouts too long is painful in non-VALGRIND, so I ended up making it
conditional.
```
# First it expires.
wait_for(lambda: only_one(l3.rpc.listinvoices('inv1')['invoices'])['status'] == 'expired')
# Now will get autocleaned
wait_for(lambda: l3.rpc.listinvoices('inv1')['invoices'] == [])
> assert l3.rpc.autoclean_status()['autoclean']['expiredinvoices']['cleaned'] == 1
E assert 3 == 1

This is actually what the autoclean plugin wants, especially since
you can't otherwise delete a payment which has failed then succeeded.
But insist on neither or both being specified, at least for now.

autoclean was using 98% of its time in memmove; we should simply keep
an offset, and memmove when it's empty. And also, only memmove the
used region, not the entire buffer!

Using `listfowards` for this wrong; expose this directly if people
care (and unlike listforwards, which could be deleted, we have to
remember these while the channel is still open!).

Changelog-Added: JSON-RPC: `listhtlcs` new command to list all known HTLCS.
And document that we never know payment_hash.
Changelog-Added: JSON-RPC: `listforwards` now shows `in_htlc_id` and `out_htlc_id`
Changelog-Changed: JSON-RPC: `listforwards` now never shows `payment_hash`; use `listhtlcs`.
Normally, we'd use the delete_columns function to remove the old
`short_channel_id` string field, *but* we can't do that for sqlite, as
there are other tables with references to it. So add a FIXME to do
it once everyone has upgraded to an sqlite3 which has native support
for column deletion.

Although it's deprecated already (because it stores as string), it's
better to make the name explicit. And create a new helper which stores as BIGINT.

This one directly contains the scids of the channels involved, not
references, so can outlive the channels. As a side-effect, however,
it now never lists `payment_hash`. Having it listed (via join) is not
possible as it is a *string* in the channels table, and difficult
anyway because of channel aliases.

contrib/giantnode.py shows we're spending a lot of time looking up

I was wondering why the workflow never published, turns out we were triggering on
branch pushes only, not tags. So the branch would get pushed, but the tag is pushed
afterwards, and thus not triggering.
