This new API allow resuming a task if it was paused, while leaving it to stopped stated if it was stopped or not started yet. This new API can be useful for callback driver workflow, where you basically want to pause and resume the task when buffers are notified while avoiding the race with a gst_task_stop() coming from another thread.
