Pete Harris 7c7117e309 Remove per-texel error weights 
Every use is replaced with a block-wide per-channel weighting.
This removes support for:

* -v and -va for effor function control
* -b for deblocking
* -a for alpha weighting (still supported for RDO)

pete 6cfc4973f3 Significantly improve the quality of -fastest 
Improve the quality of -fastest by an average of 1dB, albeit at
around 0.5x the performance. With this change -fastest is ~2x
the speed of -fast.

The goal of this change was to improve predictability of the codec
and avoid the steep quality-to-perf drop-off for effort settings
under 10, where the loss in quality was much faster than the gain
in performance compared to effort settings above 10.

pete ccc5369a64 Use the mode0 fast-pash less for -fastest quality 
- For 6x6 this improves IQ by around 0.3dB for ~8% performance.
- For 8x8 this improves IQ by around 0.5dB for ~15% performance.

Both are still substantially faster than -fast (2-3x).
