What the summary says.
Created attachment 32810 [details]
Change to webcore.gypi so that the upstreamed files are visible to gyp in the chromium build downstream.
Did a test build of chromium and of pure webkit (just to be certain).
After this is committed, landed, and rolled down to chromium, we can kill the chromium side files.
