    flxdec: rewrite logic based on GstByteReader/Writer

    Solves overreading/writing the given arrays and will error out if the
    streams asks to do that.

    Also does more error checking that the stream is valid and won't
    overrun any allocated arrays.  Also mitigate integer overflow errors
    calculating allocation sizes.
