Most of your suggestions are agreeable; a few minor quibbles follow.

What do you think of list_head() and list_tail() instead?

I don't see the need for anything more than set_difference() and
set_difference_ptr() -- if we're passed a T_IntList or a T_OidList, we
can examine the list tag and do the Right Thing automagically. ISTM we
only need the xxx_int() and xxx_oid() variants when something in the
function's signature depends on the type of the list's elements.
