Now, nobody requires nsIContentIterator interface. So, we can get rid of it. Unfortunately, there is no macro to keep the inherited class, ContentSubtreeIterator, in the cycle collection to make it keep managing ContentSubtreeIterator::mRange without nsISupports interface. Therefore, this patch moves it into ContentIteratorBase temporarily. Anyway, the following patch makes those classes not refcountable. At that time, this issue will be fixed.
