each_node: like each, but returns a node instead of the element.
insert_sorted: takes a comparison function
append: empties the second list; must be O(1). Currently can't be because of back-head-pointers - decide whether to get rid of them.

What is a node for a dlist?

Node is the handle that the user must use to e.g. remove from the dlist, or insert_before/insert_after. Doing each_node would allow a user to decide where to insert (e.g. for insert_sorted) without open-coding the iteration.

Found during ICFP (#2928).
