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.
