Obtain the control-rate for this object. Audio processing #GstElement
objects will use this rate to sub-divide their processing loop and call
gst.object.ObjectGst.syncValues in between. The length of the processing segment
should be up to control-rate nanoseconds.
If the object is not under property control, this will return
GST_CLOCK_TIME_NONE. This allows the element to avoid the sub-dividing.
