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 patch is adapted from Tor bug 1517.
To offer some protection against timing attacks by JS content pages, in this
patch we round the various time-exposing APIs (such as Date and
Event.timeStamps) to the nearest 100 ms when the pref "privacy.resistFingerprinting" is on.

This function updates CSS Animations with servo's computed values.
In bug 1341985, this function will be called with null servo's computed values
in the case where the target element is in display:none subtree.

We will need to remove animation from timeline before calling Animation::UpdateTiming() in order to fire the cancel event.
In bug 1264125, we request one more tick after calling Animation::Cancel(), however we won't need to call this request if we apply this changeset.

The first step of Animation::Cancel(), it will release owning element.
However we will use owning element for queueing the CSS-Animations event, So we will need to release owning element after calling Animation::Cancel() in order to fire the animationcancel event.

In Web Animations specification, if the animation effect is in none of the any phase, it define as 'Idle' phase. [1]
But, in the gecko, it defined as 'Null' phase.
So we will need to use 'Idle' phase for consistency.

In the case when the animation index is changed, we have to update the layer
because the index affects composite order.
Currently UpdateCascadeResult() does it but the function will check
only which cascade level wins in the cascade level and request restyle
only when the winner is changed, e.g. when a CSS animation overrides a
CSS transition, etc. So we should call request restyle respectively when the index
is changed inside each Animation class.

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.

This patch removes a loop for the new temporary animation collection in
CheckAnimationRule. The old collection is passed to CSSAnimationBuilder,
and CSSAnimationBuilder removes each animation which matches to new animation
name in it.
:birtles took care of storing animations in AnimationCollection in reverse order.
Thanks so much!

When updating animations, we shouldn't unnecessarily clobber the "wins in
cascade" state of their properties since this can lead to unnecessary restyles
when we then decide we need to update the cascade.
