Initial drop of libwebp for Chromium.

[Peter Kasting, 2010-10-06 23:35:09]

Rubber-stamp LGTM.  I still think we should pursue pulling this in via DEPS.

out of curiosity why didn't we go the DEPS route?

right  now, the libwebp-decode is hosted by a git repo,
whereas Chromium somehow prefers svn for DEPS. Can
be worked around, but will take more time...

The issue according to maruel is that while gclient supports pulling from
git repositories, depot_tools does not contain a git executable on windows,
so we aren't yet in a position to use git repositories for cross-platform
dependencies.

It would also be reasonable to host this library under
/trunk/deps/third_party/, and then pull it via DEPS.  That way, once we do
add git to depot_tools, we would be able to just change where DEPS points.
 But, I'm not sure this is enough of a reason to justify the work.
