This is unrelated to this bug (the assertion can already fail without the
patches in this patch queue) but I uncovered it while writing the tests in the
next patch which will trip the assertion that is removed in this patch.

A forthcoming spec change will require that Animatable.animate() and other
methods that mutate animations do not flush style:
https://github.com/w3c/csswg-drafts/issues/3613
Bug 1525809 will add web-platform-tests for this change once it is made (and
tweak the behavior introduced in this patch if necessary).
Currently Firefox and WebKit will flush styles when calling
Animatable.animate(). This is undesirable since this method will _also_
invalidate style. As a result, if content triggers multiple animations in
a single animation frame, it will restyle every time it creates an animation.
This patch removes the style flush from a number of these methods.
In general the style flush is not necessary. For example, we don't need to flush
style before getting the computed style to pass to UpdateProperties. That's
because if there are pending style changes, then UpdateProperties will be called
with the updated style once they are applied anyway. Flushing style first means
that we may end up resolving style twice, when once would be sufficient.
For GetKeyframes() however, when used on a CSS animation, it should return
the most up-to-date style so for that call site we *do* want to flush style.
The test case added in this patch will fail without the code changes in the
patch. Specifically, we will observe 10 non-animation restyles (from the
5 animations) if we flush styles from SetKeyframes.

Without this fix, various tests in
dom/animation/tests/mozilla/test_restyles.html will fail once we remove the
style flush from KeyframeEffect::SetKeyframes. That is because we will fail to
set mCumulativeChangeHint correctly when we initially set up the keyframe's
properties and then never update it since UpdateProperties will return early
when it determines the properties have not changed.

Regarding the missing dom:: specifications, presumably this currently works
because in the unified build this file gets combined with something with "using
namespace mozilla::dom" but this will fail if the chunking of the unified build
changes.

Summary: Really sorry for the size of the patch. It's mostly automatic
s/nsIDocument/Document/ but I had to fix up in a bunch of places manually to
add the right namespacing and such.
Overall it's not a very interesting patch I think.
nsDocument.cpp turns into Document.cpp, nsIDocument.h into Document.h and
nsIDocumentInlines.h into DocumentInlines.h.
I also changed a bunch of nsCOMPtr usage to RefPtr, but not all of it.
While fixing up some of the bits I also removed some unneeded OwnerDoc() null
checks and such, but I didn't do anything riskier than that.
This should avoid a sometimes unnecessary heaps allocation and also avoids the
possibility of having a "none" previousBaseStyles.

Now we no longer update the corresponding display items for the animations that
are prevented from running on the compositor if the animations themselves don't
generate any change hints, e.g the same value is specified in both 'from' and
'to' keyframes. So that we can enable the reftests that we had been suffering
from continuous MozAfterPaint events.

I.e., continue the loop if the CSS property is not what we want and set the
result value only if the CSS property is effective.
This change makes the function match
what KeyframeEffect::GetEffectiveAnimationProperties does in the similar loop
so that we can unify the iteration into a single function in the next commit.

This change gets all effective CSS properties on an nsIFrame just once.
Note that LayerAnimationInfo::GetCSSPropertiesFor intentionally returns
nsCSSPropertyIDSet instead of nsCSSPropertyID since when we support individual
transform properties for the compositor the mapping between display item types
and nsCSSProperty has to be 1:N. E.g. all scale/translate/rotate properties are
mapped to transform display item.

If mIsRunningOnCompositor is true, the property is effective state because
CanThrottle() is called in advance of a restyle for the effect so that we can
drop the check and drop skipping in the case of non-effective properties.

The comment there was wrong. We just bail out from there only if
mIsRunningCompositor is false, so it doesn't matter whatever the layer
generation check results. (i.e., we don't bail out in the case where
mIsRunningCompositor is true).
Also, we iterate over mProperties in the LayerAnimationInfo::sRecords loop
through HasEffectiveAnimationOfProperty, so it doesn't matter that we iterate
mProperties before the loop either. We will avoid the iteration in the sRecords
loop in a subsequent patch in this series.

This feature should not be shipped until the various definitions of addition for
each additive property are properly specified.
Unlike other patches in this series, compositing is not frequently used
internally (e.g. by DevTools etc.) so there is no need to enable this by default
for system code.
Also, it turns out we have inadvertently been shipping part of this feature for
some time now. The next patch in this series will add tests for that case and
disable that part of the feature (a suitable intent to unship will follow). This
patch merely adapts and extends the existing tests without affecting the surface
area covered by the combination of the newly-added pref and the existing
dom.animations-api.core.enabled pref.
