Bug 1396723 - Simplify the trait users of DoublyLinkedList need to define. r=froydnj While the flexibility of the current trait is nice, it's actually not used to its fullest anywhere, and is boilerplate-y. While it is useful to be able to put the links anywhere, there's not much usefulness from being able to split mNext and mPrev. So instead of a trait that allows to get/set mNext and mPrev independently, we just use a trait that tells how to get a reference to a DoublyLinkedListElement from a list element itself.
