* The njs_random_t structure must be either initialized with zeros
* or initialized by njs_random_init() function. The later is intended
* mainly for unit test. njs_random() automatically stirs itself if
* process pid changed after fork(). This pid testing can be disabled by
* passing -1 as the pid argument to njs_random_init() or njs_random_stir()
* functions. The testing can be later enabled by passing any positive
* number, for example, a real pid number.
