    This commits add common elements for Ancillary Data and Closed
    Caption support in GStreamer:
    
    * A VBI (Video Blanking Interval) parser that supports detection
      and extraction of Ancillary data according to the SMPTE S291M
      specification. Currently supports the v210 and UYVY video
      formats.
    
    * A new GstMeta for Closed Caption : GstVideoCaptionMeta. This
      supports the two types of CC : CEA-608 and CEA-708, along with
      the 4 different ways they can be transported (other systems
      are super-set of those).
