Given that a video stream/frame may have only one view or both views coded with
the packing information being unavailable, this commit adds a new type value
AV_STEREO3D_UNSPEC for this purpose.
The most common case for this is container level signaling of Stereo3D video
where the specifics are defined at the bitstream level.
