Log Message:
make(1): convert Lst_Enqueue and Lst_Dequeue to nonnull variants

Except for once instance in parse.c, the usage pattern for Lst_Dequeue
was to first test whether the list is empty.  This pattern allowed the
implementation of Lst_Dequeue to become simpler since the null check is
not needed anymore.

The calls to Lst_Enqueue never pass an invalid list or a null pointer,
therefore making them strict was trivial.
