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.

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.
