Before we begin re-arranging KeyframeEffect.h we move ComputedTiming aside
since putting it in a separate file should make navigating the source
easier.

We will eventually use this in place of the various state flags stored on
AnimationCollection (e.g. mStyleRuleRefreshTime, mStyleChanging,
mHasPendingAnimationRestyle) as well as to do a more targetted update in
FlushAnimations and AddStyleUpdatesTo.
As we gradually move logic from layout/style/AnimationCommon.cpp to
dom/animation/EffectSet and EffectCompositor it makes sense to let this class
live in its own file inside dom/animation where it is used.

This added method should behave in an equivalent manner to the existing
CommonAnimationManager::GetAnimationsForCompositor except for the following
differences:
* It uses the EffectSet attached to a target element rather than one of the
AnimationCollection object on the owning element.
* It returns an array of Animation objects consisting of only those Animations
that actually have the specified property as opposed to the
AnimationCollection consisting of *all* CSS animations or *all* CSS
transitions for the element regardless of whether they run on the compositor
or not.
It may not be obvious why these two methods otherwise behave in an equivalent
fashion so the following explains how the existing code is mirrored in the new
method.
The existing code is as follows:
> AnimationCollection*
> CommonAnimationManager::GetAnimationsForCompositor(const nsIFrame* aFrame,
> nsCSSProperty aProperty)
> {
> AnimationCollection* collection = GetAnimationCollection(aFrame);
> if (!collection ||
> !collection->HasCurrentAnimationOfProperty(aProperty) ||
> !collection->CanPerformOnCompositorThread(aFrame)) {
> return nullptr;
> }
>
> // This animation can be done on the compositor.
> return collection;
> }
The new EffectCompositor::GetAnimationsForCompositor begins with two checks
performed at the beginning of CanPerformOnCompositorThread: the checks for
whether async animations are enabled or not and whether the frame has refused
async animations since these are cheap and it makes sense to check them first.
The next part of EffectCompositor::GetAnimationsForCompositor checks if there is
an EffectSet associated with the frame. This is equivalent to the check whether
|collection| is null or not above.
Following, we iterate through the effects in the EffectSet.
We first check if each effect is playing or not. In the above code,
HasCurrentAnimationOfProperty only checks if the effect is *current* or not.
However, CanPerformOnCompositorThread will only return true if it finds an
animation that can run on the compositor that is *playing*. Since playing is
a strict subset of current we only need to perform the more restrictive test.
Next we check if the effect should block running other animations on the
compositor. This is equivalent to the remainder of CanPerformOnCompositorThread.
Note that the order is important here. Only playing animations should block
other animations from running on the compositor. Furthermore, this needs to
happen before the following step since animations of property other than
|aProperty| can still block animations from running on the compositor.
Finally, we check if the effect has an animation of |aProperty|. This is
equivalent to the remainder of HasCurrentAnimationOfProperty.
If all these checks succeed, we add the effect's animation to the result to
return.
This patch also moves AnimationUtils out of the dom namespace since it seems
unnecessary. We typically only put actual DOM interfaces in the dom namespace.
The patch removes 455 occurrences of FAIL_ON_WARNINGS from moz.build files, and
adds 78 instances of ALLOW_COMPILER_WARNINGS. About half of those 78 are in
code we control and which should be removable with a little effort.

Having created composite ordering methods for the different kinds of animations
this patch adds a Comparator class so that they can be used to sort an
array of such animations.
This patch uses this Comparator object to sort the results returned by
Element.getAnimations. For this case, the order in which we create animations
and transitions happens to almost perfectly correspond with the composite
ordering defined so that no sorting is necessary.
One exception is that some -moz-* transitions may be created after transitions
that they should sort before when sorting by transition property. In this
case the sorting added in this patch should ensure they are returned in the
correct sequence.
Unfortunately, we can't easily test this since the test files we have are
intended to be cross-browser (where -moz-* properties won't be supported).
Once we implement AnimationTimeline.getAnimations (bug 1150810) we'll have
a better opportunity to test this sorting. For now, the added tests in this
patch just serve as a regression test that the sorting hasn't upset the
already correct order (and an interop test in future once we move them to
web-platform-tests).

This patch also updates the method names on PendingAnimationTracker but leaves
a number of local variables which will be fixed in a subsequent patch.

This patch is a fairly minimal rename of the AnimationPlayer interface. It
leaves a bunch of local variables and helper classes still using the word
"player". These will be addressed in subsequent patches that don't require DOM
peer review.

We define KeyframeEffectReadonly in KeyframeEffect.cpp since Web Animations also
defines KeyframeEffect and when we come to implement that I expect we'll define
it in the same class, maybe even using the same object.
This patch also adds a few missing includes in places where
KeyframeEffectReadonly is used so that we're not just cargo-culting it in.

rename : dom/webidl/Animation.webidl => dom/webidl/KeyframeEffect.webidl
Most of this is fairly obvious. However, the addition of 'override' to
ElementPropertyTransition::Name() is not strictly necessary. It was simply added
because while making these changes I accidentally dropped the 'virtual' keyword
from the method in the superclass and the compiler didn't complain. Adding this
will hopefully make it harder to create the same bug in the future.

This patch adds a hashtable to nsDocument that stores all the animation players
that are currently waiting to start. In the future it may also be used to store
players that are waiting to pause which is why the methods are called
AddPlayPending/RemovePlayPending instead of just AddPlayer/RemovePlayer.
This patch renames mozilla::ElementAnimations to mozilla::dom::AnimationPlayer
and moves the code from layout/style/AnimationCommon.cpp to
dom/animation/AnimationPlayer.cpp.
It also moves various helper classes needed by AnimationPlayer to
AnimationPlayer.cpp and moves them from the mozilla::css namespace to the
mozilla namespace.
Beyond that, there are no functional changes contained in this patch.
The renaming of various members and variables that used to refer to
ElementAnimation objects but now refer to AnimationPlayer objects--to give them
a more appropriate name--is performed in a subsequent patch.
