Add support for announcement and handling of pre-established audio connections through routing side

 As the complete initialization of the cockpit system takes some time, a few use-cases exist
 where information needs to be audible (or visible) right before the system is fully started.
 Here we mainly have:
    - system alerts
        + door open
        + seat belt missing
        + engine faults
    - parking assistant warnings
        + rear view camera screen
        + beeps if distance goes below limit

Both routing- and control-side are extended to allow notifying about such connections
