This should both be faster and simpler. Also will allow us in the future
to animate more pseudos without having to add a gazillion properties.
I think we should try to clear more stuff (maybe the whole animation
data) on unbind, but that's a bit tangential.

The motivation here is that we will want to call CSSTransition specific
functions, e.g. updating the start value of a given CSSTransition with
the latest value of the CSSTransition on the compositor, from somewhere
not in layout/style. Unfotunately nsTransitionManager.h is not exposed
and we will never want to expose it since it's purely for layout/style
stuff.

Currently we avoid posting animation restyles when unbinding an element by
removing the element from the document before deleting its animation
collections. As a result, when canceled animations go to post a restyle, they
can't find a pres context and give up posting a restyle.
However, this is problematic for two reasons:
* It means we can't remove such canceled animations from the
PendingAnimationTracker if they are present there (i.e. it regresses the fix
from bug 1223445).
* It means we can't post cancel events for such animations/transitions since we
can't lookup the appropriate AnimationEventDispatcher.
In the next patch in this series we will change that order to fix the above
problems but before we do that, we need to introduce another mechanism to make
sure that we don't post restyles when unbinding an element or else we will
regress bug 1396041.
This patch does that by introducing a flag which causes us to not post restyles
when we are doing DOM surgery. For all other cases we actually _do_ need to post
restyles in order to update the style correctly.
Without this patch, layout/style/crashtests/1396041.html would fail after
applying the next patch in this series.

This is more consistent with what the Rust bits of the style system do, and
removes a pointer from ComputedStyle which is always nice.
This also aligns the Rust bits with the C++ bits re. not treating xul pseudos as
anonymous boxes. See the comment in nsTreeStyleCache.cpp regarding those.
Can't wait for XUL trees to die.

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.

Rather than passing around a bool flag to indicate if we should be creating
an AnimationCollection when none is found, it would be a lot easier to read
if we simply introduce a separate method for this.
MozReview-Commit-ID: 6bg8jGoH5pL
By moving GetAnimationCollection to AnimationCollection itself, we can remove
a bunch of virtual methods on the animation managers, simplify call sites,
and provide better type safety by ensuring a correspondence between element
property names and concrete animation types.
One change in behavior, however, is that in doing this we can no longer
add any newly-created AnimationCollection to the corresponding manager's linked
list of collections inside GetAnimationCollection. Instead we take a bool
outparam to indicate if a new collection was created and leave managing the
linked list to the manager. This is just a temporary measure, however, since
by the end of this patch series will will eliminate this linked list altogether
along with this flag.

This patch templatizes the type of Animation stored in an AnimationCollection.
This allows us to remove a number AsCSSAnimation() calls in nsAnimationManager.
This patch also removes the AnimationPtrArray typedef. In its place we
introduce OwningCSSAnimationPtrArray and OwningCSSTransitionPtrArray but we
don't use these as widely. There was some comment previously that the typedefs
in animation code make it hard to read, particularly when these typedefs don't
make it clear if the data type is an owning reference or not.
In doing this we need to templatize CommonAnimationManager as well and move the
implementation of its (few) methods to the header file. We may be able to
remove the need for templatizing CommonAnimationManager later in this patch
series depending on how we ultimately decide to handle the lifetime of
AnimationCollection objects.
CommonAnimationManager::GetAnimationCollection is a bit messy but this will be
significantly tidied up in subsequent patches in this series.
MozReview-Commit-ID: 3ywatY53pRR
In this bug we will trim off unnecessary functionality from the animation
managers and make AnimationCollection into an independent data type
so in this patch we separate it into its own file.
It is also generally easier to navigate the source code and eliminate
cyclic dependencies between header files when there is a rough
correspondance between class names and file names (e.g. rather than having
#include "AnimationCommon.h" // For mozilla::AnimationCollection).
This patch also makes a few simplifications to include dependencies since
they're a bit of a mess (making it hard to move code around). The changes to
IncrementalClearCOMRuleArray.cpp are due to the changes to the unified build
introduced by adding AnimationCollection.cpp exposing a missing include from
that file.
