Add smart RGB->YUV conversion option -pre 4
...
New function: WebPPictureSmartARGBToYUVA()
This implement smart RGB->YUV conversion.
This is rather undocumented for now, and is triggered using '-pre 4'
preprocessing option.
This is slow-ish and use quite some memory, but should be improvable.
This is somehow a usable beta version.

- 7/24/14: version 0.4.1
This is a binary compatible release.
* AArch64 (arm64) & MIPS support/optimizations
* NEON assembly additions:
- ~25% faster lossy decode / encode (-m 4)
- ~10% faster lossless decode
- ~5-10% faster lossless encode (-m 3/4)
* dwebp/vwebp can read from stdin
* cwebp/gif2webp can write to stdout
* cwebp can read webp files; useful if storing sources as webp lossless
* tag 'v0.4.1':

JPEG decoder: delay conversion to YUV to WebPEncode() call
...
We store the raw RGB samples decoded from JPEG, and avoid precision loss.
Note that this may increase the encoding time reported by
cwebp -v, since RGB->YUV now occur during WebPEncode call
(in case of lossy), instead of ReadJPEG().
This also increases the memory use, since we're carying the
source ARGB samples around.
