Update.
* pthreadP.h (pthread_cond_2_0_t): New type. (struct pthread_functions): Use new type for 2.0 condvar callbacks. Use new type for the 2.0 condvar function prototypes. * forward.c: Use pthread_cond_2_0_t for 2.0 condvar functions. * old_pthread_cond_init.c: Use pthread_cond_2_0_t for condvar parameter. * old_pthread_cond_destroy.c: Likewise. * old_pthread_cond_broadcast.c: Likewise. Lock appropriately. * old_pthread_cond_signal.c: Likewise. * old_pthread_cond_timedwait.c: Likewise. * old_pthread_cond_wait.c: Likewise.
