    codecparsers_h264: add gst_h264_video_calculate_framerate()

    Add a new function to calculate video stream framerate which rely on
    SPS, slice header and pic timing using formula:

             time_scale                1                         1
    fps = -----------------  x  ---------------  x  ------------------------
          num_units_in_tick     DeltaTfiDivisor     (field_pic_flag ? 2 : 1)

    See section E2.1 of H264 specification for definition of variables.
