int32_t  tor_weak_random_range (tor_weak_rng_t *rng, int32_t top) 
A weak but fast PRNG based on a linear congruential generator.
We don't want to use the platform random(), since some of them are even worse than this.

void tor_init_weak_random  (  tor_weak_rng_t *  rng, 
unsigned  seed  
) 
Initialize the insecure RNG rng from a seed value seed.

int32_t tor_weak_random  (  tor_weak_rng_t *  rng  ) 
int32_t tor_weak_random_range  (  tor_weak_rng_t *  rng, 
int32_t  top  
) 
Return a random number in the range [0 , top). {That is, the range of integers i such that 0 <= i < top.} Chooses uniformly. Requires that top is greater than 0. This randomness is not cryptographically strong; do not rely on it for anything an adversary should not be able to predict.
