    Bug 33931 - Indicate bridge type in stream
    
    Use the first-byte to indicate if the following data stream contains
    default bridges or custom bridges. In addition, if the stream contains
    default bridges, then indicate if only one type of bridge should be used
    after parsing the stream.
