        * pthread.h (pthread_mutex_t): revert to (pthread_mutex_t *);
        define a value to serve as PTHREAD_MUTEX_INITIALIZER.
        (pthread_mutex_t_): remove staticinit and valid elements.
        (pthread_cond_t): revert to (pthread_cond_t_ *);
        define a value to serve as PTHREAD_COND_INITIALIZER.
        (pthread_cond_t_): remove staticinit and valid elements.
        * mutex.c (pthread_mutex_t args): adjust indirection of references.
        (all functions): check for PTHREAD_MUTEX_INITIALIZER value;
        check for NULL (invalid).
        * condvar.c (pthread_cond_t args): adjust indirection of references.
        (all functions): check for PTHREAD_COND_INITIALIZER value;
        check for NULL (invalid).

        * eyal1.c (main): Fix trylock loop; was not waiting for thread to lock
        the "started" mutex.
