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).

ae429de8f6 video: GST_EXPORT -> GST_VIDEO_API
We need different export decorators for the different libs.
For now no actual change though, just rename before the release,
and add prelude headers to define the new decorator to GST_EXPORT.

b2fd20c416 video: move videoconvert code to video library
Move the conversion code used in videoconvert to the video library
and expose a simple but generic API to do arbitrary conversion. It can
currently do colorspace conversion but the plan is to add videoscale to
it as well.

Expose the gst_video_info_align function that adds padding and does stride
alignment on a GstVideoInfo. Move this previously private function to
video-info.co

up by both the bufferpool and the video-info.

04a2610444 video: improve frame_flags
Rename the frame_flags to flags. Because they are flags on the frame object it
does not need the redundant frame_ prefix.

format and dimension arguments.

91ffe7dd5e video: Clean up interlaced flags and enums
There's a new GstVideoFrameFlags enum now that contains the frame
specific flags only. GstVideoFlags does not contain the TFF/TFF/ONEFIELD
flags anymore because these are strictly frame specific.

Also add fallback to parse these fields from the GstBufferFlags in
gst_video_frame_map() if there's no GstVideoMeta attached to the buffer.

21bf4f04f3 video: fix some video formats
Rename the offset field in GstVideoFormatInfo to poffset to avoid confusion with
the offset of the plane in the buffer. The poffset is the offset in the plane
where the first byte of the component data can be found.
Properly implement the COMP_OFFSET calculations.
Fix YV12 and YVU9, simply use the same offsets as the regular I420 and YUV9
variants, we use the plane info to reorder components already.
Improve the unit test.
