David Parks a72dd8f316 Bug 1125325 - Store TabParents with their WindowRoot. r=smaug
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.
