Function rt_event_delete

src/ipc.c:1926–1944

* @brief This function will delete an event object and release the memory space. * * @note This function is used to delete an event object which is created by the rt_event_create() function. * By contrast, the rt_event_detach() function will detach a static event object. * When the event is successfully deleted, it will resume all suspended threads in the event list.

 *           ONLY USE the rt_event_detach() function to complete the detachment.
