66c810bc3c add a -yuv option to dwebp (very similar to -pgm)
It will decode to raw (flat) YUV format, similar to what
cwebp can take as input. Makes the PSNR/SSIM calculation easier.

b7adf37621 allow WebPINewRGB/YUVA to be passed a NULL output buffer.
If a NULL pre-allocated buffer is passed, a buffer will be automatically
allocated.

Mans Rullgard
090b708a00 NEON optimised yuv to rgb conversion
- along the lines of the SSE chroma upsampling.
Total speedup is ~30%.

4% speed loss on YuvToRgbXX conversion using tables instead
of 14-bit fixed precision. TODO(later): investigate, and compare
to x86.
