During CAT feature discovery the capacity bitmasks (CBMs) associated with all the classes of service are initialized to all ones, even if the class of service is not in use. Introduce a test that can be used to determine if a class of service is in use. This test enables code interested in parsing the CBMs to know if its values are meaningful or can be ignored. Temporarily mark the function as unused to silence compile warnings until it is used.
