    asfdemux: Add sanity checks when reading asf_stream_video_format

    It should report a size of at least 40 bytes
    Also check for the size of the remaining data (i.e. codec_data)

    asfdemux: Add check for invalid/corrupt asf object

    An asf object can't realistically be bigger than 2**32 bytes.

    If it reports a size bigger than that, consider it corrupt and properly
    propagate the error back.
