WebKit API change LGTM.  Please be sure to disable these features appropriately on chromium-android.

Is this the best way to do this?  I would have expected the embedder to do this work.

No, this isn't beautiful. We should not have this kind of #if in RuntimeEnabledFeatures.cpp

I'll do following three steps to make RuntimeEnabledFeatures.cpp clean:

1. RuntimEnabledFeatures.cpp: Change #if OS(ANDROID) to #if PLATFORM(CHROMIUM) && !OS(ANDROID) to set false, otherwise set true -- keep current behavior
2. content/renderrer/render_thread_impl.cc: RenderThreadImpl::EnsureWebKitInitialized() of Chromium side, I'll add enableInputTypeDateTime(false), ... for !OS(ANDROID)
3. Then, remove #if PLATFORM(CHROMIUM) && !OS(ANDROID) from RuntimeEnabledFeatures.cpp

Please touch InputType.h to rebuild *InputType.cpp.  Without it, Chromium-win bots will fail to build.

Flags will be introduced to WebCore.  "for Chromium port" is false.
