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 need to call nsBindingManager's method from ServoStyleSet in a later
patch.
Also, we call nsStyleSet::SetBindingManager() immediately after we call
nsStyleSet::Init(). Therefore, we could pass binding manager to Init()
directly, and delete SetBindingManager().

I plan to use it for now to force a full document restyle when a standalone rule
changes or something like that.
In practice, we can do better sometimes, and we may just want to propagate to
the StyleSet all the style change notifications in order to have access to the
rule that changed and all that...
But for now this seemed easier than adding other four or five functions to
StyleSetHandle.

The idea is to be able to call the right function during style resolution time
without doing a linear walk via nsCSSAnonBoxes::IsNonInheritingAnonBox.

The basic idea here is as follows:
* Rule nodes are reference-counted, but releasing them adds them to a linked
list rather than freeing them. This allows for the reuse that motivated the
original GC scheme.
* We get rid of the marking, and instead rely on the reference count.
* Sweeping no longer requires a complicated traversal. We just pop items
off the free list until it's empty. When a child is destroyed, its parent
may go onto the free list.
* We remove special handling for the root node, and use a regular reference-counted
edge from the style set.
* The free list automatically asserts that it's empty (meaning all nodes have been
freed) in its destructor, which runs when the style set is destroyed.
* We get rid of the list of style context roots on the style set. We still need
a count though, because of the HasCachedStyleData check.
