I used do-webcore-rename from Blink/WebKit which is very good at doing this kind of search-replace. Also removed toRefPrtNativeArray after conversion since it previously had two separate flavors. Both versions are no longer used so I've removed the code until we need one again. https://www.irccloud.com/pastebin/5C16p5cE is the diff I used to do-webcore-rename TBR=abarth@chromium.org
