The difference between the PRCList and LinkedList is that the end of a LinkedList is represented by nullptr, so we don't need to worry about getting the first element when we iterate pass the last element. The majority of the changes is due to this difference. Also, simplify do-while loops by using for-loops in nsCounterManager and nsQuoteList.
