Algo timer is simplified timer designed for qnetd algorithm. Instead of full timer only one can exists per client. Workflow is: - In one of algorithm callbacks qnetd_client_algo_timer_schedule is called - On timeout .timer_callback is called (for example qnetd_algo_test_timer_callback). It's possible to set send_vote and result_vote to send vote info to client - It's possible to discard timer by calling qnetd_client_algo_timer_abort Timer is automatically deleted on client disconnect. To make all this possible, qnetd main loop now has support for timer-list (main_timer_list). To be able to handle error and disconnect client from timer callback, client has schedule_disconnect. If this is set to 1, client is disconnected on current call of poll loop. Signed-off-by: Jan Friesse <jfriesse@redhat.com>
