8955da2149 example_util.h: avoid forward declaring enums 
doing so is not part of ISO C; removes some pedantic warnings.
use webp/decode.h to pickup VP8StatusCode instead.

2bcad89b4c allow some more stdin/stout I/O 
* allow reading from stdin for dwebp / vwebp
 * allow writing to stdout for gif2webp

by introducing a new function ExUtilReadFromStdin()

Example use: cat in.webp | dwebp -o - -- - > out.png

Note that the '-- -' option must appear *last*
(as per general fashion for '--' option parsing)

d640614d54 update copyright text 
rather than symlink the webm/vpx terms, use the same header as libvpx to
reference in-tree files
