352a4f49ab Get rid of PackLiteralBitLengths() 
[and in turn a malloc]. Also, a few related const fixes.

d673b6b9a0 Change the predictor function to pass left pixel 
instead of pointer to the source.

b2f99465a7 Fix CopyTileWithPrediction() 
so that it uses original values of left, top etc for prediction rather than the
predicted values of the same. Also, do some renaming in the same to make it
more readable.

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.

After this Change, will implement the EncodeImageInternal() method.

c04eb7be9d tcoder.c: define NOT_HAVE_LOG2 for MSVC builds 
no version of msvc currently implements log2(). unconditionally define
NOT_HAVE_LOG2 in this case to simplify building libwebp sources in other
projects.
