	(struct waitlist): Don't add cond.
	* sysdeps/pthread/aio_notify.c [!DONT_USE_BOOTSTRAP_MAP]
	(__aio_notify): Use AIO_MISC_NOTIFY instead of pthread_cond_signal.
	* sysdeps/pthread/aio_suspend.c [!DONT_USE_BOOTSTRAP_MAP]: Don't
	use condvar, use AIO_MISC_WAIT.
	* sysdeps/pthread/lio_listio.c: Likewise.
	* rt/Makefile (tests): Add aio_suspend.
