[aat] Another try at fixing Lookup null objects...
...
Ugly as hell, and don't even understand why some bits are needed.
But the logic is sound.

Unfortunately our static asserts (DEFINE_SIZE_STATIC) don't actually

Disallow null-enabled offsets to unsized structures...
...
...like UnsizedArrayOf<>.
This fixes a class of crasher bugs, mostly with color and AAT tables. We
cannot use nullable offsets to varsized data that does not declare min_size,
because it's nost safe to use our fixed-size null pool for types that have
their size external. So, use non_null'able offsets for these.
A further enhancement would be to make use of min_size in Null<> itself.
Will try that after.
