Create interface for the ALT_REF_AQ class Current commit is just an API template for the rest of the code, and I will add inner logic later. Altref frames generate a lot of bitrate and at the same time other frames refer to them a lot, so it makes sense to apply special compensation-based adaptive quantization scheme for altref frames. E.g., for blocks that are good predictors for the future apply rate-control chosen quantizer while for bad predictors apply worse one. Change-Id: Iba3f8ec349470673b7249f6a125f6859336a47c8
