   5 * Sort linked list in place.
   6 * - get_next_fn() returns the next element given an element of a linked list.
   7 * - set_next_fn() takes two elements A and B, and makes B the "next" element
   8 *   of A on the list.
   9 * - compare_fn() takes two elements A and B, and returns negative, 0, positive
  10 *   as the same sign as "subtracting" B from A.
