New function: random-sample.
Implements reservoir sampling.
* rand.c (radom_float_impl): New static function, made out of
random_float. Returns double, giving us access to the unboxed
result
(random_float): Now a wrapper around random_float_impl: boxes
the result of random_float.
(elrd, flrd, random_sample): New static functions.
(rand_init): Register random-sample intrinsic.
* txr.1: Documented.
* stdlib/doc-syms.tl: Updated.
