Make ranged for loops work with STACK_OF(T).

My original plan here was to make STACK_OF(T) expand to a template so
the inner type were extractable. Unfortunately, we cannot sanely make
STACK_OF(T) expand to a different type in C and C++ even across
compilation units because UBSan sometimes explodes. This is nuts, but so
it goes.

Instead, use StackTraits to extract the STACK_OF(T) parameters and
define an iterator type.
