it was a NULL value.

59e1ab5576 Fix an assert() that could fail when reading a blob or text value larger than 1GiB from the database (requires a non-default build configuration). This is an assert() fix only, production builds were functioning correctly.

80d74f0934 In the regexp extension, limit the maximum value of integers in the 
"{p,q}" syntax, as performance of the NFA used to do pattern matching
is linear in the maximum such integer.  The limit is SQLITE_MAX_REGEXP_REPEAT
which defaults to 999.  This helps to prevent DoS attacks in systems that
make use of the regexp extension.

a4476ea1fa Overhaul the wasm build to (A) support more coexisting variants, e.g. 32/64-bit of both vanilla and esm, and (B) build each variant to its own subdir so that they can build in parallel. It can, with make -j4, now build all new variants in half the time it previously took for just the 32-bit builds. The new build logging output, though unconventional, serves two purposes: (A) improve my build-time situational awareness and (B) it help demystify some of the build steps and output files.

49a37f333a Improvements to imposter tables: (1) They are read-only unless writable-schema 
is enabled.  (2) Because they are now read-only, the ".imposter" command
in the CLI no longer requires the --unsafe-testing command-line option.
(3) Imposter tables do not participate in a PRAGMA integrity_check and hence
do not cause false-positive errors.  However, you can still do an
integrity_check on the the imposter table itself by naming the imposter
table as the argument to integrity_check.
