This change moves most of the logic for the threadsafety check into nsAutoOwningThread, rather than having part of the logic live in nsAutoOwningThread and part of the logic live in nsDebug.h. Changing this also forces us to clean up a couple of places that replicated the logic that lived in nsDebug.h as well.
