Refactor rate distortion cost structure This commit makes a struct that contains rate value, distortion value, and the rate-distortion cost. The goal is to provide a better interface for rate-distortion related operation. It is first used in rd_pick_partition and saves a few RDCOST calculations.

Best_rd breakout in rd partition search. About 15% faster for bus (speed 0) first 50 frames @ 1500kbps, which goes from 1min36 to 1min24. Results become slightly better (+0.2% on derf/yt, +0.4% on hd), probably because of a bugfix for skipmode in super_block_yrd(). Overall speed change (on derfraw300) is roughly -13%. This can probably be improved further by caching best_yrd between partition searches. Also, we might be able to get more speedups by always doing PARTITION_NONE before PARTITIONS_SPLIT, not just at the sb8x8 level. Change-Id: I83736949ebd5b4a3b400ee688d7661913fefc98b

Experimental rd bias based on source vs recon variance. This experiment biases the rd decision based on the impact a mode decision has on the relative spatial complexity of the reconstruction vs the source. The aim is to better retain a semblance of texture even if it is slightly misaligned / wrong, rather than use a simple rd measure that tends to favor use of a flat predictor if a perfect match can't be found. This improves the appearance of texture and visual quality on specific test clips but is hidden under a flag and currently off by default pending visual quality testing on a wider Yt set.

Change speed and rd features for formatting bars. Change speed features / behavior for split mode when there is an internal active edge (e.g. formatting bars). Remove some threshold constraints in rd code near the active edge of the image. Add some plumbing for left and right active edge detection. Patch set 5. Limit rd pass through for sub 8x8 to internal active edges. This takes away any speed penalty for most clips but keeps the enhanced edge coding for the more critical case of internal image edges Change-Id: If644e4762874de4fe9cbb0a66211953fa74c13a5

Changes to use of rectangular partitions. Changes to allow more use of rectangular partitions at speeds 1 and 2 for content classed by the first pass as animation and for blocks near the active image edge. This has quite a big impact in quality for the animated test sequence but also hurts encode speed for speed 2. For other content types the impact on both speed and quality is small. Added some plumbing for detection of internal vertical image edges. Change-Id: I3fc48de2349f8cb87946caaf0b06dbb0ea261a9a
