New functions: cshuffle and cnshuffle.
These functions find random cyclic permutations.
* eval.c (eval_init): Register cshuffle and cnshuffle
intrinsics.
* lib.c (nshuffle_impl): New static function, formed out of
nshuffle.
(nhuffle): Now wrapper around nshuffle_impl.
(shuffle): Also wraps nshuffle_impl rather than nshuffle.
(cnshuffle, cshuffle): New funtions.
* lib.h (cnshuffle, cshuffle): Declared.
* txr.1: Documented new functions. Also added warning
about limitations on permutation reachability in relation
to PRNG state size.
