Update the lightningd <-> channeld interface with lots of new commands to needed to facilitate spicing.
Implement the channeld splicing protocol leveraging the interactivetx protocol.
Implement lightningd’s channel_control to support channeld in its splicing efforts.
Changelog-Added: Added the features to enable splicing & resizing of active channels.
This is almost always true already; fix up the few non-standard ones.
This is enforced with an assert, and I ran the entire test suite to
double-check.

This avoids the mess where we override db_fatal for teqsts, and keeps it
generic.
Also allows us to get rid of one #if DEVELOPER, and an ugly global for
bookkeeper.

It is possible for db_column_bytes() to return 0 and for
db_column_blob() to return NULL even when db_column_is_null() returns
false. We need to short circuit in this case.

This was always the intent, but now we have to reconstruct from the
disparate fields.
This means `option_anchor_outputs` is now redundant.

I couldn't figure out why my new SQL query was returning 0 rows,
and it was because we were ignoring errors.

Changelog-None
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.

Because it used internal routines, it didn't pass operations through the
db hook! So make it use the generic routines, with the twist that they
are not translated.
And when we use this in a migration hook, we're actually in a
transaction.
This, in turn, introduces an issue: we need to be outside a transaction
to "PRAGMA foreign_keys = OFF", but completing the transaction when
there is a db hook actually enters the io loop, freeing the tmpctx!

The initial snapshots on an already-running lightningd are expected to
be unbalanced, but this shouldn't cause users to long for the green,
green grass of home.
This controls the Art of Noise.
