I was inspired by the previous patch to remove FrameLayerBuilder.h from
nsDisplayList.h too.

As the second step in dividing functionality between AnimationPlayer and
Animation, this patch moves the AnimationTiming member from AnimationPlayer to
Animation.
Most of this patch is simply moving code around. However, one significant
functional difference is that Animation::GetLocalTime() uses the mParentTime
member which is set when the Animation is updated by the player it is attached
to.
Other less significant differences are:
* AnimationPlayer::GetLocalTime is renamed to GetCurrentTimeDuration
In Web Animations, animation players have a (writeable) "current time" and
animations have a (read-only) "local time".
We would call the method simply "GetCurrentTime" (instead of
"GetCurrentTimeDuration") but GetCurrentTime is the name of the method used in
the content-facing API where it returns a double.
* "IsCurrent" is defined on both AnimationPlayer and Animation with the version
in AnimationPlayer serving mostly as a convenience shortcut to the version on
Animation.
* Animation::GetComputedTiming (previously on AnimationPlayer) now makes the
timing parameter optional since most of the time it is not needed.
As the first step in dividing the functionality currently contained in
AnimationPlayer between AnimationPlayer and Animation this patch moves the set
of keyframe properties to the Animation.
These properties are returned from the Animation by a couple of Properties()
methods that provide direct access to the member variable. In future it is
anticipated that the non-const version will be replaced with an appropriate
setter function. This will likely happen when we implement a separate
KeyframeEffect object as defined by the Web Animations API.
With regards to error checking, nsAnimationManager checks the result of
AnimationPlayer::GetSource() and handles the case where it is nullptr.
nsTransitionManager, however, simply asserts that GetSource() is never null much
like it also asserts that there is only one property with one segment in the
animation. Eventually this code should be made more generic which will probably
happen in bug 999927.
Now that we have both AnimationPlayer and Animation in use we need to clarify
which object we are referring to. This patch renames a number of member and
local variables to better reflect whether they point to an AnimationPlayer or an
Animation.
This patch is mostly renaming only with one exception. Since we are touching
a number of local variables used in loops (for looping over the array of
animation players) we take the opportunity to replace a number of instances of
uint32_t with size_t since that is the preferred type for array indices now.
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.

rename : layout/style/AnimationCommon.cpp => dom/animation/AnimationPlayer.cpp
rename : layout/style/AnimationCommon.h => dom/animation/AnimationPlayer.h

The current reference frame is still the same as our reference frame because we set and restore it in nsFrame::BuildDisplayListForChild before this. So we need to actually compute it.
Calling Layer::SetVisibleRegion multiple times in a transaction can result in
unnecessary IPC traffic.
This patch removes Intersect(childGfxBounds). This is only needed to
restrict the visible region to something sane for 3D transforms, and this will
be fixed up in a later patch.
