Change the CCHelper class to be an instanced instead of a static pattern. The CCHelper instances all share an interface to the common clock service and register/unregister a callback handler in response to there being CCHelper instance in the system or not. This brings usage of the CCHelper into like with the new auto-disable functionality of the common time service. For any given process, whenever there are CCHelper instances active, the process will maintain a callback target to the common clock service and will be considered to be an active client. Also change all of the users of the CCHelper interface to manage the lifecycle of their new CCHelper instances. Change-Id: I7c28c5d70d9b07ba7407b4ac706e7e7d7253001b
