* rename mozilla::Module struct entries to be clearer
* change Module documentation so that the last entry is { NULL } in all cases (the compiler will 0-expand the structure)
* remove NS_XPCOM_COMPONENT_REGISTRY_FILE
* add MOZ_MEDIA/MOZ_OGG/MOZ_WAVE/MOZ_WEBM ifdefs to nsHTMLMediaElement.h and nsContentUtils.cpp
