5b630501e9 Skip memcpy(x, x) in qunique().
It has undefined behavior.  Follow the precedent of commit
9a9473f3cc.  No back-patch, since the
master branch alone has this function.

7815e7efdb Add reusable routine for making arrays unique.
Introduce qunique() and qunique_arg(), which can be used after qsort()
and qsort_arg() respectively to remove duplicate values.  Use it where
appropriate.
