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.

nsHtml5Atoms are very similar to dynamic nsAtoms. This patch removes the former
in favour of the latter, which leaves nsAtom as the only subclass of nsIAtom.
nsAtom::mKind is still used to distinguish dynamic atoms from HTML5 atoms, and
the HTML5 parser still uses manual memory management to handle its HTML5 atoms.
nsHtml5AtomEntry::mAtom had to be changed from an nsAutoPtr to a raw pointer
because nsAtom's destructor is private.
