Also includes a refactoring of the Ant xml scripts to use a common template (contributed by shashishekhar@chromium.org). As part of this, I also continued Torne's effort of removing our reliance on environment variables. Unfortunately this currently means that you have to specify 5 gyp flags:
ANDROID_SDK, ANDROID_SDK_ROOT, ANDROID_SDK_TOOLS, ANDROID_SDK_VERSION, ANDROID_TOOLCHAIN.
This'll get better as we make further use of the checked in sdk both upstream and downstream. The problem stems from the android tree and released sdk having different configurations.
