To avoid breaking downstream, the "interface" directories were copied into a new "common_video/include" dir. The old headers got pragma warnings added about deprecation (a very short deprecation since I plan to remove them as soon downstream is updated). The header guards are also identical to avoid mixing them up in the transition.
