add new BRC method
VA_RC_ICQ: Intelligent Constant Quality. Provided an initial ICQ_quality_factor,
adjusts QP at a frame and MB level based on motion to improve subjective quality.
VA_RC_CFS: Constant Frame Size.
VA_RC_PARALLEL: For hierachical B, B frames can be refered by other B frames.
Currently three layers of hierachy are defined:
B0 - regular B, no reference to other B frames.
B1 - reference to only I, P and regular B0 frames.
B2 - reference to any other frames, including B1.
In Hierachical B structure, B frames on the same layer can be processed
simultaneously. And BRC would adjust accordingly. This is so called
Parallel BRC.
