In the next patch we want to add a method called
GetUnanimatedStyleContextForElementNoFlush but that's much too long. Instead it
seems better to just drop 'ForElement' from all these methods since it should be
fairly obvious we are getting the style context for an element given that the
first argument is an element.

The purpose of ResetWinsInCascade() in SetTarget() ensures that
RequestRestyle(Layer) is invoked for the new target in the case when
composite order or CSS cascading or order is changed due to chaging target
element, but RequestRestyle(Layer) will be called right after setting
the new target in SetTarget() explicitly.

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.

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.

The previous patch in this series renamed nsCSSProperty to nsCSSPropertyID.
This patch renames nsCSSPropertySet to nsCSSPropertyIDSet accordingly.
This patch is generated by the following commands (note: if you're running
using OS X's sed, which accepts slightly different flags, you'll have to
specify an actual backup suffix in -i, or use gsed from Homebrew):
hg stat -c \
| cut -c 3- \
| tr '\n' '\0' \
| xargs -0 -P 8 gsed --follow-symlinks 's/\bnsCSSPropertySet\b/nsCSSPropertyIDSet/g' -i''
Then:
hg mv layout/style/nsCSSPropertySet.h layout/style/nsCSSPropertyIDSet.h
... and finally, manually renaming nsCSSPropertySet in the include guard in
nsCSSPropertyIDSet.h.

We don't actually need to re-calculate if the updated properties are the
same as the old one. This change avoids problematic nested calls of
nsStyleSet::GetContext() in particular cases.

Previously, when fetching an nsPresShell, we would look up the current realm
document and get the pres shell for it. This patch makes us call GetPresShell()
which uses GetRenderedDocument() which corresponds to the composed document of
the target effect which seems more consistent since it is the target effect we
will use as context for computing CSS values (as required by [1]).

When we apply paced spacing, we have to check if there are still null computed
offsets after applying paced spacing to paceable Keyframes because the
calculation of distance may be failed or some Keyframes are not paceable in
the specific range. Therefore, using -1 would be easier to check it.
Also, add a const, kComputedOffsetNotSet, to represent this invalid value.

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).

In order to raise an assertion in CanIgnoreIfNotVisible() which will be
introduced in part 3 when the cumulative hint is not properly, we should skip
the calculation when mProperties is empty.
BuildSegmentsFromValueEntries now needs base nsStyleContext to calculate
the change hints.
If the change hint is not set correctly, we will check it in
CanIgnoreIfNotVisible() introduced in a subsequent patch (part 3).
We will need to request a restyle and unregister the current target in
SetTarget(), and there are many duplicate code segments for them now, so wrap
them for reusing the code.

1. Define OwningAnimationTarget.
2. Replace the KeyframeEffectReadOnly::mTarget/mPseudoType members with
a Maybe<OwningAnimationTarget> mTarget member.

WebIDL referes to KeyframeEffect::SetFrames(), which is derived from
KeyframeEffectReadOnly::SetFrames() in terms of implementation.
In addition, make KeyframeEffectReadOnly::ConstructKeyframeEffect call
KeyframeEffectReadOnly::SetFrames() to simplify the code.

It turns out that std::stable_sort on Mac and Android use this.
Bug 1263500 tracks doing something more efficient on those platforms.
