Unlike the other one this function does not need an old nsStyleContext.
This function just resolves style without all animation data in the first place.
The existing ResolveStyleWithoutAnimation is renamed to
ResolveStyleByRemovingAnimation.

The new name makes the sense of the condition much clearer. E.g. compare:
NS_WARN_IF_FALSE(!rv.Failed());
with:
NS_WARNING_ASSERTION(!rv.Failed());
The new name also makes it clearer that it only has effect in debug builds,
because that's standard for assertions.
Use SetEffectNoUpdate() for the procedure of setting effect, and let SetEffect()
also calls PostUpdate(), so we can use SetEffectNoUpdate() if we don't want to
call RequestRestyle(RestyleType::layer).

This is a pre-patch for part 5, which is trying to make our code closer to the
spec. Some methods in KeyframeEffectReadOnly belong to AnimationEffectReadOnly,
so first, use AsKeyframeEffect() to access those keyframe-related methods, and
then add virtual methods for timing-related methods to AnimationEffectReadOnly.

Add mTransitionProperty and mTransitionToValue into CSSTransition, so we can
retrieve the original property and ToValue after setting a different effect.

This implements the spec change in 21de090dac
The spec change refers to a binary 'animation direction' flag. Instead of that,
however, we just pass the playback rate along and use it inside
GetComputedTimingAt since this seems simpler.
Also, this patch moves the implementation of
KeyframeEffectReadOnly::GetComputedTiming from the header file into the .cpp
file. This is because with this change, GetComputedTiming needs to call
mAnimation->PlaybackRate() and so mozilla::dom::Animation needs to be a complete
type. However, simply including Animation.h doesn't work because of a cyclic
dependency between KeyframeEffect.h and Animation.h. We might be able to fix
this later but since yet-to-land bug 1049975 moves this code around a lot, I'd
rather not touch it too much just now.

While resolving style context, the primary frame of the target element
has previous style context so if we don't pass the newly created nsStyleContext,
UpdateCascadeResults uses the previous style to get overridden properties, it
will result unexpected cascading results.

Add a new file, KeyframeEffectParams.h, and define the basic data
members nsString for the spacing mode.
Also, add one more argument, const KeyframeEffectParams&, to the
constructors of KeyframeEffect(ReadOnly).

Transitions on the compositor sometimes go further ahead while the
main-thread is busy. When the transition on the compositor is replaced by a
new one, until now we calculate the current position of the old one with the
most recent refresh time. But if the replace is done on a busy frame, the
calculated position will be far from the real position on the compositor.
As a result, we can see jumping transitions after busy frames.
To mitigate this issue, we should calculate a plausible current position of
the old one with the current time just before sending the new transition to
the compositor, i.e., after all JS callback works have done.
The plausible value is stored into KeyframeEffectReadOnly::mProperties, not
into mKeyframes. If we store the value into keyframes,
KeyframeEffectReadOnly::GetKeyframes() will return a different values after
busy frames.
Note that with this patch getComputedStyle() does not return the plausible
value because this patch does not affect styling process. getComputedStyle
issue will be fixed in bug 1273834.

Now we can throttle some sort of animations which run on the main thread
as well as animations on the compositor. So, AreAsyncAnimationsEnabled checks
should be removed.
The check in PresShell::HandleEvent might be replaced with checking
nsIDocument::mNeedStyleFlush, but I am not sure.
Currently if we have transition-property: 'all' and trigger a transition
on the 'color' property we will end up generating a transition on
-webkit-text-fill-color even if that property is disabled.
However, when we later call StyleAnimationValue::ToValue() in
nsTransitionManager::UpdateTransitions() to see if there are any transitions we
need to cancel, the comparison for currentValue != anim->ToValue() will pass
(since, as of the first patch in this patch series, ToValue() returns a null
value) so we end up cancelling the transition as soon as we create it).
Nevertheless, we will still trigger the warning introduced in the first patch
in this series when we call ToValue().
This patch stops us from creating transitions in the first place (and hence
triggering the warning). It also removes the code that suppresses transition
events for transitions on disabled properties since we should no longer be
generating such transitions in the first place (unless the pref is switched
while the transition is in motion which is probably not worth worrying about).
Note that we only test if the property is enabled for all content. This is
consistent with what we do throughout animation code including the existing
code in nsTransitionManager which iterates through shorthand sub-properties
using CSSPROPS_FOR_SHORTHAND_SUBPROPERTIES with the flag
nsCSSProps::eEnabledForAllContent.
The test case in this patch doesn't actually fail without this change, all it
does it trigger the warning in StyleAnimationValue::ToValue() introduced
in the first patch in this series. It's still a useful regression test however,
particularly if we later upgrade the warning in StyleAnimationValue::ToValue()
to a fatal assertion.
