Native library functions for lists.

None of these are actually defined here. Instead, native implementations are
paul@354 7
substituted when each program is built. It is, however, important to declare
paul@354 8
non-core exceptions used by the native functions because they need to be
paul@354 9
identified as being needed by the program.
