LibVideo: Rename "ColorRange" to "VideoFullRangeFlag"
That matches the terminology used in ITU-T Rec. H.273, PNG's cICP chunk, and the ICC cicpTag. Also change the enum values to match the values in the spec -- 0 means "not full range" and 1 means "full range". (For now, keep the "Unspecified" entry around, and give it value 2. This value is not in the spec.) No intended behavior change.
