41d31dcd19 avoid UB when calling ctype functions
The character classification functions in <ctype.h> are designed to
classify characters returned by <stdio.h> getchar() and friends, which
return characters as signed integers in the range 0 to 255 or EOF. The
behavior of the ctype functions is undefined if they are passed a value
outside of that range, which may happen if they are passed a char-typed
value and the system's char type is signed.

<ccan/str/str.h> defines some inline utility functions that perform the
necessary cast to coerce a char-typed argument into the allowed value
range. Call these wrappers instead of the bare ctype functions when
classifying char-typed characters.

e051ba6bbf sqlite3: consistently comment where we want to upgrade.
Now you can grep for 'sqlite3 version' and see where we would like
to update.

Debian 11 (Bullseye) and Ubuntu 20.04 (Focal) ship with SQLite 3.31.1.
RHEL 9 ships with 3.34.1.  Fedora 38+ uses SQLite 3.40+.

Unfortunately, RHEL8 ships with 3.26.0, and is still on maintenance Support
(security fixes, no new features): runs until May 31, 2029.

04f485aee0 db: add generic warn/error function.
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.

e853cdc3ff db: fix sqlite3 code which manipulates columns.
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!
