As I've said before, as module owner I prefer that MOZ_ASSERT_IF not be
used in the module because I consider it to be unreadable. However, a
few uses have crept in, and this patch removes them.
I consider it to be unreadable because the name looks like a name that
uses smalltalk-ish naming conventions, i.e., with a part of the name
corresponding to each parameter, in order. However, the parameters are
in the order opposite the name.
This was written primarily with the vim commands:
:%s/MOZ_ASSERT_IF(\([^,]*\),/MOZ_ASSERT(!\1 ||/
:wn
followed by manual cleanup for indentation and removal of !!.

We create interpolatematrix and accumulatematrix from Servo side
not on the main thread, so we cannot use nsCSSValueList_heap (which is not
thread safe so we cannot create it and destroy it on different threads).
Therefore, we use nsCSSValueSharedList to represent the cloned lists in
interpolatematrix and accumulatematrix.

When any of the link preshints (link, vlink, alink) on <body> are set, we store
a Servo declaration block to hold the color from the hint.
This uses a one-off approach instead of `nsMappedAttributes` that is used for
other preshints because it depends on element state and also it affects links
through the document (as opposed to the element where the attribute is set).

If we add/remove important rules, we should call MaybeUpdateCascadeResults()
to make sure EffectSet::mPropertiesWithImportantRules is correct, and so we can
avoid that these important rules are overridden by animations running on
compositor. Currently, we call MaybeUpdateCascadeResults only while iterating
elements which needs to be restyled, so we should request a restyle on this
element whose important rules are changed.

We need to traverse rule tree to get the important rules, so we will not
override them if they have animations running on compositor.

This allows us to access metadata using `match` instead of comparison with
atoms, which makes it doable to get the pseudo-element flags in the future.

This change does the following:
* Introduce a new smart pointer called CounterStylePtr which either
holds an AnonymousCounterStyle strongly, or a named CounterStyle
managed by CounterStyleManager weakly, and use it to replace all
RefPtr<CounterStyle> around the codebase.
* Rename CounterStyleManager::mCacheTable to mStyles to reflect the
fact that it is used to manage all styles, not just for caching.
* Add a retired styles list which collect all named CounterStyle
evicted from mStyles, and post a PostRefreshObserver to destroy
objects in that list after next flush.
* Remove helper functions for counter style in nsStyleList and expose
mCounterStyle directly, to make code simpler with the new pointer.
Reason for adding a new smart pointer type rather than making their
AddRef/Release behave like BuiltinCounterStyle is that, it is possible
that after a flush, some stale style structs may still be alive. They
can contain pointer to destroyed CounterStyle objects. Although the
actual content may never be accessed anymore, RefPtr may still access
the object for refcounting during destruction.

This is mostly a mimic of what we do in
GeckoCSSAnimationBuilder::FillInMissingKeyframeValues().
In Gecko we iterate over the properties just once because we can take the
index for both the synthesized start and end keyframe and easily look them up
as needed. However, in this patch we synthesize the start and end keyframes
separately and iterate over the properties twice because that's easier than
getting two indices and then later calling another FFI to dereference each of
them, and neater than getting back two pointers

This patch implement several things:
1. Implement a new constructor for nsStyleImageRequest to receive an existing
ImageValue from the caller.
2. Implement Gecko_ImageValue_Create to allow stylo to create a gecko::ImageValue
object.
3. Implement Gecko_SetXXXXImageValue to allow stylo to pass a created ImageValue
back to gecko.

I've chosen this approach mainly because there's no other good way to guarantee
the model is correct than holding the snapshots alive until a style refresh.
What I tried before this (storing them in a sort of "immutable element data") is
a pain, since we call into style from the frame constructor and other content
notifications, which makes keeping track of which snapshots should be cleared an
which shouldn't an insane task.
Ideally we'd have a single entry-point for style, but that's not the case right
now, and changing that requires pretty non-trivial changes to the frame
constructor.
