Now that accessing nsIContent slots is not a blob of virtual function calls, we
should be able to unify logic here, and speed up the not-so-rare case for
chrome, while keeping the usual case fast.

We should consider slot as a parent in ChildIterator: if slot's
`assignedNodes` is not empty, use `assignedNodes`, otherwise, use direct
children as fallback content.
Also, GetFlattenedTreeParentNodeInternal should be changed to use
`assignedSlot` instead of `DestInsertionPoints`.
We check for them when the node doesn't have the MAY_BE_IN_BINDING_MNGR flag,
but the flag is not precise, so in presence of dynamic changes that somehow make
the node assigned, then unassigned, like changing the binding, it may not be
correct.

Otherwise we may inappropriately style it or what not. This asserts with the
patches of bug 1414999 plus the cleanup of bug 1418456, since we no longer do
StyleNewChildren (which walks over the flattened tree children).
Too bad that GetXBLBinding is a virtual call in Gecko, probably can do just
MAY_BE_IN_BINDING_MGR...

It's a sub-class of nsAtom, useful for cases where you know you are dealing
exclusively with static atoms. The nice thing about it is that you can use
raw nsStaticAtom pointers instead of RefPtr<>. (In fact, the AddRef/Release
implementations ensure that we'll crash if we use RefPtr<nsStaticAtom>.)

This is a follow-up patch for bug 1392970. Since we only set CustomElementDefinition on a custom element
which is "custom", we could add more assertion to ensure that.

This is pretty much a straight-forward change except for a single thing, the
UpdateInsertionParent calls.
However, I cannot make any sense of them. They go through the inserted children
setting the insertion point, but then ClearInsertionPoints() is called.
ClearInsertionPoints calls XBLChildrenElement::ClearInsertedChildren, which sets
all the insertion points to null anyway.
Thus, I've removed that function completely.

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.

This commit removes:
* layout.css.style-attr-with-xml-base.disabled pref
* deprecation XMLBaseAttributeForStyleAttr
* code path for getting base URI of style attr considering xml:base

This patch merges nsAtom into nsIAtom. For the moment, both names can be used
interchangeably due to a typedef. The patch also devirtualizes nsIAtom, by
making it not inherit from nsISupports, removing NS_DECL_NSIATOM, and dropping
the use of NS_IMETHOD_. It also removes nsIAtom's IIDs.
These changes trigger knock-on changes throughout the codebase, changing the
types of lots of things as follows.
- nsCOMPtr<nsIAtom> --> RefPtr<nsIAtom>
- nsCOMArray<nsIAtom> --> nsTArray<RefPtr<nsIAtom>>
- Count() --> Length()
- ObjectAt() --> ElementAt()
- AppendObject() --> AppendElement()
- RemoveObjectAt() --> RemoveElementAt()
- ns*Hashtable<nsISupportsHashKey, ...> -->
ns*Hashtable<nsRefPtrHashKey<nsIAtom>, ...>
- nsInterfaceHashtable<T, nsIAtom> --> nsRefPtrHashtable<T, nsIAtom>
- This requires adding a Get() method to nsRefPtrHashtable that it lacks but
nsInterfaceHashtable has.
- nsCOMPtr<nsIMutableArray> --> nsTArray<RefPtr<nsIAtom>>
- nsArrayBase::Create() --> nsTArray()
- GetLength() --> Length()
- do_QueryElementAt() --> operator[]
The patch also has some changes to Rust code that manipulates nsIAtom.

This is the reason similar assertion failures can't be reproduced with elements
and stuff like fieldset and form validity changes.
nsBindingManager::ContentRemoved calls SetXBLInsertionParent, which clears all
the Servo data from the subtree eagerly, which is a waste when the actual
binding parent is the same (null).

The virtual call to this method shows up in profiles, and therefore
would be nice to avoid if possible. We can do that by making
nsIWeakReference hold the weak reference itself and therefore
implementing a non-virtual QueryReferent method.
