til: wire seed up to til randomizers
til_setting_desc_t.random() and til_module_randomize_setup() now take seeds. Note they are not taking a pointer to a shared seed, but instead receive the seed by value. If a caller wishes the seed to evolve on every invocation into these functions, it should simply insert a rand_r(&seed) in producing the supplied seed value. Within a given randomizer, the seed evolves when appropriate. But isolating the effects by default seems appropriate, so callers can easily have determinism within their respective scope regardless of how much nested random use occurs.
