a89a3230c9 wicdec: support alpha from WebP WIC decoder
the container check may not be strictly necessary now that the alpha
check has matured and the library will detect usable alpha, but it's
safer to fix this case first before making larger changes.

b27ea8525a wicdec,icc: treat unsupported op as non-fatal
ICC extraction via GetColorContexts may fail due to the operation not
being supported with e.g., bitmaps.

9cf9841b5e libwebp: Unicode command tools on Windows
Define macros in examples/unicode.h to use Unicode argv
on Windows. Keep char everywhere on Unix since it handles
UTF-8 without any change.

Impact:
 - All fopen () and SHCreateStreamOnFile(),
 - All fprintf() printing file paths,
 - All strcmp() used with "-",
 - File path parsing,
 - Gif reading.

Concerned executables from examples/ and extras/:
  anim_diff, anim_dump, vwebp, vwebp_sdl,
  cwebp, dwebp, gif2webp, img2webp,
  webpmux, webpinfo, webp_quality, get_disto

When compiled on Windows with Unicode enabled, webpmux and
img2webp will not work when used with an argument file and
will print "Reading arguments from a file is a feature
unavailable with Unicode binaries."
