648be3939f Added implementation for various lossless functions 
- VP8LEncAnalyze, EvalAndApplySubtractGreen, ApplyPredictFilter,
  ApplyCrossColorFilter
- Added palette handling and transform buffer management in VP8LEncodeImage()
- Add Transforms (subtract Green, Predict, cross_color) to dsp/lossless.c.

These are more-or-less copied from src/lossless code.
