Removes active_worst_quality feedback Removes certain cases of feedback of active_worst_quality, and removes it from the RATE_CONTROL structure. Now active worst quality is expected to be computed locally in the q picking function during the encode. Making temporal filter strength depend on avg_frame_qindex rather than on active_worst_quality actually improves performance esp. for yt. derf: +0.038% yt: +0.359% Change-Id: I1fe5a343034b55af9322289165321f00ac0827b1
