A reference to a document (and the act of saving it) can outlive the browser tab it was originally loaded in, and this needs to be reflected in IPC in order to avoid MsgRouteError crashes; see bug for more info. Note that we still need to pass the PBrowser when starting persistence, because that's the only handle the parent has on the top-level document; see comments in this patch for more info. Also makes TabChildBase::GetDocument public, because it's just a wrapper around WebNavigation() which is already public, to avoid code duplication.
