ab66becaae introduce a separate WebPRescalerDspInit to initialize pointers 
so that we keep the details of WebPRescaler in utils/rescaler.c
when possible.

a437694a17 multi-thread fix: lock each entry points with a static var 
we compare the current VP8GetCPUInfo pointer to the last used.
This is less code overall and each implementation is still
testable separately (by just changing VP8GetCPUInfo, but not
a separate threads!)

87c3d53180 method=0: Don't evaluate any predictor 
and apply Paeth predictor (predictor#11) for the low effort (m=0) mode.

For 1000 image PNG corpus (m=0), this change yields speedup of 25% at lower quality
range and about 10% for higher quality range.

a3946b8956 enc_neon: fix building with non-Xcode clang (iOS) 
check for __apple_build_version__ to distinguish the two; a version
check could work as Apple bumped Xcode's to 5.x/6.x, but it's unclear
how upstream will deal with their versioning as they go 3.6+, so avoid
it for now.

Pascal Massimino
bad775715a simplify the Histogram struct, to only store max_value and last_nz 
we don't need to store the whole distribution in order to compute the alpha

Later, we can incorporate the max_value / last_non_zero bookkeeping
in SSE2 directly.

57606047ec encoder: switch BPS to 32 instead of 16 
this is a first step to unifying encoding/decoding cache stride
and possibly sharing the prediction functions in dsp/

With this layout, there's a little (~7%) space lost with unused samples.
But no speed change was observed.

e0c809ad23 Move Entropy methods to lossless.c 
Move all the Entropy evaluation methods to lossless.c (from histogram.c).
There's slight difference in the way entropy is computed for evaluating
entropy in prediction methods and histogram (literal) for huffman trees.
Plan (later) to merge few (static) methods and reduce the code size.

This change has no impact on the compression speed/density.
