+ *  rtems_task_delete

+ *  This directive allows a thread to delete itself or the thread

+ *
+ *  Input parameters:
+ *    id - thread id
+ *
+ *  Output parameters:
+ *    nothing           - if id is the requesting thread (always succeeds)
+ *    RTEMS_SUCCESSFUL - if successful and id is
+ *                           not the requesting thread
+ *    error code        - if unsuccessful
