nsContentUtils::CallOnAllRemoteChildren calls a callback on all tabs connected to a given window but it has only worked in Firefox e10s tabs. This patch adds a list of (weak) references to each top-level document's WindowRoot so that e.g. the nsPresContext can access them instead of using nsContentUtils. This provides a solution to the problem of finding remote PBrowsers generally.
