With the introduction of prerendering in Chromium it is now possible for RenderFrameHosts (RFH) to move between FrameTrees. As a consequence we can no longer rely on FrameTreeNode IDs to uniquely identify a RFH over its lifespan. We must now switch to using GlobalRenderFrameHostId (child_id, frame_routing_id) instead for that purpose. Additionally, we simplify existing code by using the GlobalRenderFrameHostId struct in all places that previously used a (render_process_id, render_frame_id) pair, since these concepts are equivalent. See https://crbug.com/1179502#c8 for additional background.
