libwebp: Unicode command tools on Windows

Browse Source 
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."
