The new roots callback mechanism makes it possible to traverse the gc objects on the stack without needing the stack to be an gc object. This also uncovered a nasty bug in apfl_stack_pop where we passed in a wrong mem pointer into apfl_resizable_splice. We should probably find a way to make the apfl_resizable_* functions a bit safer, the need for casting stuff to void** easily hides errors.
