04d5d6d38f rand:ntru_get_rnd_poly_small: written a function to generate a random polynom 
like get_urnd_int_small but with the random source from /dev/random
instead of /dev/urandom

71b8f4cbeb Added static mp_digit get_rnd_int_small(int *sign) 
but it takes about ~40minutes to generate a x^500
polynom with /dev/random.
