Sets the queue to flushing state if @flushing is %TRUE. If set to flushing
state, any incoming data on the @queue will be discarded. Any call currently
blocking on #gst_data_queue_push or #gst_data_queue_pop will return straight
away with a return value of %FALSE. While the @queue is in flushing state,
all calls to those two functions will return %FALSE.
