Without this change, we can end up asserting in ComputeVariablesData and
crashing in CSSVariableResolver::Resolve due to not finding any variable
declarations on the rules we matched, when we have content like in the
crashtest added here, i.e. variables inheriting into a pseudo like
::first-line and animations on the element inside the ::first-line.
We could solve this alternatively by removing the assertion and making
CSSVariableResolver::Resolve handle a null aDeclarations more gracefully,
but since we can save the effort of recomputing the Variables struct in
this case, we may as well.

Now, remove Layer::mSourceURI, there are several benefit of doing this:
1. Reduce the size of nsStyleImage::Layer.
2. By storing style image and url information in nsStyleImage, we can remove
many verbose comments. That is becasue there is no need to explain why we use
mSourceURI here, or why we use nsStyleImage there anymore.
3. Since all inforamtion is stored in on place, nsStyleImage, we can setup image
request or URLs by one single Gecko_SetUrlImageValue call.

This patch implements two things:
1. Add one extra type, nsStyleImageType::eStyleImageType_Url, and puts data of
this type in nsStyleImage::mUrlData.
2. Export SetURLValueData and GetURLValueData from nsStyleImage
With these chnages, we can simply use nsStyleImage::mUrlData to replace
Layer::mSourceURI in the next patch.

Per bug 1322570 comment 46, it's not easy to replace ComputedJustifyItems()
and UsedJustifySelf()'s internal nsStyleContext::GetParent() without
correctness penalty, so we use GetParentAllowServo() for now.
Also, fix the reftest.list added in bug 1334403 which incorrectly wrote test
page as reference page.

Since font-language-override can only have a single three-letter tag, and it is
eventually converted to uint32_t while creating gfxFontStyle, we should be able
to move the conversion ahead, to an earlier stage.
In this patch, we move the ParseFontLanguageOverride to nsRuleNode, so we could
do the nsString-to-uint32_t conversion during computing time.

This change is to use gecko_enum_prefix in helpers.mako.rs, so that we do not
need to manually write code for nsStyleDisplay::mTransformBox.

Use eCSSUnit_Function to store the frames timing function. Also, add one more
css keyword: frames.
The following changes are included in this:
1. Parser changes.
2. Serialization.
3. Computation in nsRuleNode.
4. Invalid and other values in property_database.js

This introduces a basic framework for servo's style system to be able
to query the style of presentation attributes which it can then insert
into the cascade. It uses that framework to implement the size and
color attributes on <font>.
There are a number of improvements that can be done on top of this:
- Implement all other properties
- Abstractify the ruledata parameter of the mappers using templates or virtual dispatch so that it can be a Servo decl block instead
- Implement aforementiond abstraction over Servo decl blocks (this obsoletes the code in the first item above, so it might just be better to skip that and directly do this)
- Replace uses of nsHTMLStyleSheet with an abstract base class containing common elements between Servo and Gecko
I'd prefer for these to be done in separate steps.

Because the new function checks types, we need to change the fullCorner type
in nsComputedDOMStyle::GetEllipseRadii() and
StyleAnimationValue::ExtractComputedValue() from uint8_t to |Corner| to fix
build error.

The "default" case in EnumerationToLength() is not needed anymore because
StyleShapeRadius is an enum class, which cannot have other values.
