Remove all support for FOO_GETTEXTIZE and alert users to FOO_AUTOPOINT
as the recommended solution in its stead. We can use the standard
check-deprecated-variable for this, because from a user perspective
FOO_AUTOPOINT is pretty-much a drop-in replacement.

The warnings about FOO_GETTEXTIZE_OPTS are no longer relevant, because
they will only make sense if FOO_GETTEXTIZE was already set.
