* sysdeps/pthread/aio_misc.h [!DONT_USE_BOOTSTRAP_MAP]
(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. * rt/tst-aio9.c: New file.
