In a subsequent patch, we will have another struct like
KeyframeValueEntry, but storing an StyleAnimationValue and an
ComputingTimingFunction object (not a pointer). So we split
KeyframeValueEntry into two, retaining the KeyframeValueEntry name for
the base class and naming the current one KeyframeStringValueEntry.
The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.
CLOSED TREE makes big refactorings like this a piece of cake.

We need to do this so effects can query their owning animation for the current
time and avoid falling out of sync. Furthermore, this pointer is needed
for a number of other bugs (e.g. bug 1166500 comment 12, or bug 1190235)
anyway.
Since getFrames() must gather all properties set at a given keyframe
offset time for a given easing function, we need to provide a total
ordering for ComputedTimingFunction objects. Until the spec defines how
to do this, we sort first by NS_STYLE_TRANSITION_TIMING_FUNCTION_*
value, then second by the four values in a cubic-bezier() function (in
order) or the integer and optional keyword in a steps() function.
Because we don't support automatic spacing of keyframes yet,
ComputedKeyFrame.computedOffset is always the same as Keyframe.offset.
Another assumption made is that the value of easing for a Keyframe
object at 100% should be the same as the value from the previous
Keyframe for the same property. An alternative would be to leave off
easing from that Keyframe, which would need the default value for that
IDL dictionary member removed (otherwise it would always be set to
"linear").
Since Keyframe.easing should reflect the {transition,animation}-timing-
function value relevant to each keyframe, we'll need to store on
nsTimingFunction the specific timing function value that was used, and
copy it down into ComputedTimingFunction for
KeyframeEffectReadOnly.getFrames() to access. This includes storing
whether the optional start/end keyword in a steps() function was
specified.
KeyframeEffectReadOnly uses IsFinishedTransition to exclude finished transitions
from certain tests. This check, however, is redundant in each case.
This is because any effect marked as IsFinishedTransition will have the
following properties:
- owning animation's PlayState() == Finished or Idle
- animation phase = after or null
- progress = null (this is because transitions don't fill forwards)
The long-term plan is to drop the mozilla::css namespace altogether. Before we
go to much further with refactoring code in AnimationCommon, we should drop
usage of the mozilla::css namespace. Specifically, this patch moves the
CommonAnimationManager and AnimValuesStyleRule classes to the mozilla namespace.

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.
