Radek Hvizdos 31364dc841 Add initial webp image compression support. 
Only basic webp compression is supported (the only tunable is 0-100%
compression adjustment), without EXIF metadata.
Motion build scripts are configured to build in the support by default
and will emit an error if the needed library is missing. Suport can be
manualy disabled at configuration stage adding --without-libwebp.

Documentation update will follow in a separate commit.

Tested on x86-64 Linux only.
