Profiler labels can't currently be used in mozglue, because the profiler's code is in libxul, and mozglue cannot depend on libxul. This patch addresses this by basically duplicating AutoProfilerLabel in mozglue. libxul passes two callback functions to mozglue to do the actual pushing/popping of labels. It's an annoying amount of machinery, but it is unavoidable if we want to use profiler labels within mozglue. --HG-- extra : rebase_source : 4bcb6fb0f050bba42c23d92d01f9c56611f8518f
