Currently we avoid posting animation restyles when unbinding an element by
removing the element from the document before deleting its animation
collections. As a result, when canceled animations go to post a restyle, they
can't find a pres context and give up posting a restyle.
However, this is problematic for two reasons:
* It means we can't remove such canceled animations from the
PendingAnimationTracker if they are present there (i.e. it regresses the fix
from bug 1223445).
* It means we can't post cancel events for such animations/transitions since we
can't lookup the appropriate AnimationEventDispatcher.
In the next patch in this series we will change that order to fix the above
problems but before we do that, we need to introduce another mechanism to make
sure that we don't post restyles when unbinding an element or else we will
regress bug 1396041.
This patch does that by introducing a flag which causes us to not post restyles
when we are doing DOM surgery. For all other cases we actually _do_ need to post
restyles in order to update the style correctly.
Without this patch, layout/style/crashtests/1396041.html would fail after
applying the next patch in this series.

This reduces a lot the boilerplate that's needed in order to add simple binding
functions.
This starts using &Foo and Option<&Foo> instead, and as a result we need to
remove the servo_function_signatures test, which is a bit unfortunate.
I think it's worth though, this causes problems on some platforms (see bug
1534844), and messing up the functions signature is not something that I've ever
seen (other than bug 1308234, which already had all the FooBorrowed mess which
I'm removing).
Also, cbindgen understands references and Option<&Foo>, so it will be the way to
go in the future.
After this patch we can also remove HasSimpleFFI, but I've kept it for now since
I still use it in a few places, and this patch is quite big on its own.

It took me a long time to understand why
KeyframeEffect::HasEffectiveAnimationOfPropertySet behaved so differently to
KeyframeEffect::HasAnimationOfPropertySet. This patch attempts to clarify that
while making KeyframeEffect::HasEffectiveAnimationOnPropertySet a little more
generally useful. This will allow us to tidy up the various animation checks in
nsLayoutUtils later in this patch series.
Ultimately, however, we should make this check part of the regular compositor
animation vetting machinery in bug 1534884. That should remove a number of
inconsistencies such that we don't need the extended comments added in this
patch.

Since bug 1524480 we set the NS_FRAME_MAY_BE_TRANSFORMED frame bit when needed
in RestyleManager::ProcessRestyledFrames so that it is now redundant to also set
it from KeyframeEffect.
Furthermore, setting frame bits from KeyframeEffect is a little fragile since it
depends on the life cycle of the KeyframeEffect which is independent of the
nsFrame. If we can avoid doing that, we probably should.

We use DisplayItemType as the input of HasAnimationsForCompositor, and
nsCSSPropertyIDSet as the input of GetAnimationsForCompositor.
The caller of HasAnimationsForCompositor just wants to check if there is
any compositor animation for a display item, so we can replace it by the
display item, and get the properties from this display item.
However, the caller of GetAnimationsForCompositor may use a subset of
transform-like properties for getting scale factors, or use all the
transform-like properties for sending all transform animations to the
compositor thread.

This is more consistent with what the Rust bits of the style system do, and
removes a pointer from ComputedStyle which is always nice.
This also aligns the Rust bits with the C++ bits re. not treating xul pseudos as

Can't wait for XUL trees to die.

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

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.

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.
