The JS engine does not export symbols outside of XUL, so having these defined inside mozglue apparently causes linking errors on some platforms with the patches in bug 1120016. This patch moves enough methods outside of mozglue that the patch in that other bug will still link on all platforms, without moving so much out that there are other linking errors. --HG-- rename : xpcom/glue/nsCycleCollectionParticipant.cpp => xpcom/base/nsCycleCollectorTraceJSHelpers.cpp
