* sysdeps/pthread/aio_misc.h: Mark __aio_requests_mutex,
	__aio_enqueue_request, __aio_find_req, __aio_find_req_fd,
	__aio_free_request, __aio_notify, and __aio_sigqueue as hidden.

	* sysdeps/pthread/aio_suspend.c (aio_suspend): Set errno to the result
	of pthread_cond_wait if there was an error.  Use pthread_cleanup_*
	instead of __lbic_cleanup_region_*.
