    stream-device: Define Quality Indicator messages
    
    These messages are used to transmit streaming quality indicators from
    the streaming device to SPICE Server.
    
    The message is a variable-length, zero-terminated string.
    
    A new capability is introduced (STREAM_CAP_QUALITY_INDICATOR) for
    SPICE server and streaming agent capabilities negotiation.

    protocol: Define an enumeration for Quality Indicator messages
    
    These messages are used to transmit streaming quality indicators from
    SPICE client to SPICE server.
    
    The message data structure is defined in spice-common/spice.proto:
    
        message {
            Data data @to_ptr;
        } @declare quality_indicator;
