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.
