Bug 1400459 devirtualized nsIAtom so that it is no longer a subclass of
nsISupports. This means that nsAtom is now a better name for it than nsIAtom.

We should not be declaring forward declarations for nsString classes directly,
instead we should use nsStringFwd.h. This will make changing the underlying
types easier.
The list returned by getElementsByName is cached, however, it's rebuilt
frequently due to content mutations. We can avoid rebuilding the list when
the attribute changed is not the name attribute. We can also speed up the
name matching process by skipping the elements that do not have a name
attribute.
