This option remaps internal parameters to better match
the expected compression curve of JPEG and produce output files
of similar size, but with better quality.

If it's not a partial file and parser returns PARSE_NEED_MORE_DATA, then
consider it to be PARSE_ERROR.

It will decode to raw (flat) YUV format, similar to what
cwebp can take as input. Makes the PSNR/SSIM calculation easier.

If a NULL pre-allocated buffer is passed, a buffer will be automatically
allocated.
+ add some parameter checks.

store values to a temporary variable before calling functions that take
vector types.
removes non-standard constructs such as:
(uint8x8x2_t){{ a, b }}
fixing:
src/dsp/upsampling_neon.c:69:32: error: macro "vst2_u8" passed 3
arguments, but takes just 2

Fixes: https://code.google.com/p/webp/issues/detail?id=140
- 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.

This copies metadata selected by -metadata from the input to the output
if present.
Currently there is no WIC support for Windows builds.

When the config option '--enable-libwebpdecoder' is specified, the
lean decoder library 'libwebpdecoder' will be created in addition to
libwebp. Also dwebp binary will be linked to libwebpdecoder, if this
config option is specified.

Actually, it turns out we now should never call these functions
with a zero size, otherwise something is wrong in the logic.
