Add WebRTC DEPS for Android builds.

Do we need Chromium copyright header?

How are the DEPS dependencies being pulled down? I.e. who finds this file.

Is this usable to set up a Chromium workspace matching the waterfall.

I know you answer this in the cl description but I think it makes sense to
document it somewhere a developer can find it.

Since Chrome doesn't have one in src/DEPS, I don't think so.
The webrtc.DEPS directory is added as a solution in the .gclient spec, then the
contents of its DEPS file is pulled down just as regular dependencies.
I couldn't add src/third_party/webrtc in here though, since gclient then
complains about a conflict since it already exists in Chromium's src/DEPS.
Because of that, it had to be left out here and has to be configured in
custom_deps of the Chromium src/ solution instead.
Yes, this is usable for everyone that wants to setup a Chromium workspace to
build and run WebRTC Android tests with it, including the bots. 
The advantage of this approach compared to the one you suggested in
https://code.google.com/p/webrtc/issues/detail?id=1882 is that if the
dependencies change, we just update webrtc.DEPS/DEPS and don't have to
communicate the changes. That approach also didn't pin the revision for
google-gflags, which we should.
Yes, we should replace the documentation in
https://code.google.com/p/webrtc/issues/detail?id=1882 or the future public
webrtc.org page, with this as soon we've confirmed it works as intended.
