- 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.

no version of msvc currently implements log2(). unconditionally define
NOT_HAVE_LOG2 in this case to simplify building libwebp sources in other
projects.

- Android.mk should include dec/enc/upsampling sse2 variants. This
provides sse2 optimizations when compiling for Android/x86
- LOCAL_ARM_NEON should be set to true when compiling for armeabi-v7a.
Otherwise __ARM_NEON__ is not defined and all neon code is removed by
the preprocessor.
