...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.
This makes a lot of code safer. We only try modifying the object in one
place, after making sure it's safe to do so. So, do a const_cast<> in
that one place...
