This patchset is an umbrella for all FFI fixes and refactoring to be
done in #9145.
The first patch is a refactoring, and it will be useful for us when we
do #4738. The next two patches are just some FFI bugs to be fixed. The
last three patches are minor fixes use-after-free references of the
`cts->tab` objects.
