Overview of changes in Chrome DEPS:
$ svn diff http://src.chromium.org/chrome/trunk/src/DEPS -r 277350:280149

which can be compared with the output of:
$ svn cat http://webrtc.googlecode.com/svn/trunk/DEPS | grep chromium_deps | sed 's/^ *//' | sort | uniq

in a WebRTC checkout, gives the following relevant changes:
* buildtools 5d8997:fb782d
* third_party/android_tools c6e658:fbd420
* tools/gyp 1927:1944
* tools/swarming_client ae8085:aea506

BUG=3441
TEST=Local compile on most platforms (since trybots currently cannot detect DEPS-changes properly).
