9dceb6ca52 video: Add support for VANC and Closed Caption 
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).
