Our BrowsingContext currently supports 1 target. So we have a per-BC target_id. Previously, our target had 1 "frame" - our page. So we often treated the targetId as the frameId. But to work with frames, we need page-specific frameIds and loaderIds. This tries to clean up our ids (a little). frameIds are now ids derived from a new incrementing page.id. This page.id has to be passed around (via http Requests and through notifications) in order to properly generate messages with a frameId.
