stylo: Bug 1374233 - Clamp interpolated values for properties which need to be restricted
Some properties only accept non-negative values, or values greater than or equal to one. It is possible to produce an negative interpolated values while using negative timing functions, so we have to apply a restriction to these values to avoid getting invalid values.
For example, line-height must be non-negative, but the output progress of some timing functions (e,g. cubic-bezier(0.25, -2, 0.75, 1)) may be a negative value, so the interpolated result of line-height is also negative.

This shaves a fair amount of time of stylist rebuild.
Most of the extra remaining overhead are memory allocations...
I'll try to get those sorted out next, though fixing that may overlap quite a
bit with the work Cameron is doing in bug 1382925.

style: Invert storage of selector maps to key off origin first.

This will make it easier to avoid rebuilding all cascade levels when only a style sheet at a particular level changes.

Avoid adding id selectors that are in the rule hash keyed by that ID to the list
of revalidation selectors.
This partially fixes bug 1369611 (we could look at the rule hash itself to avoid
inserting some more into the list of revalidation selectors).
remove testing feature from stylo_tests
`stylo_tests` currently requires a separate version of the `style` crate, compiled with the `testing` feature, so a function testing the size of specified values can be accessed. With a few tweaks, we can make the information needed for the test available to the `stylo_tests` crate directly, eliminating the need for a separately-compiled `style` crate.
This doesn't matter much for Servo itself (it might make CI times slightly faster?), but Gecko automation/development would like to run `stylo_tests`, and not having to compile two versions of the `style` crate (or have a dead, test-only function hanging around in the `style` crate) would be a win.

Fix fixed position items with parents with CSS clips
In order to properly handle CSS clipping, we need to keep track of what
the different kinds of clips that we have. On one hand, clipping due to
overflow rules should respect the containing block hierarchy, while CSS
clipping should respect the flow tree hierarchy. In order to represent
the complexity of items that are scrolled via one clip/scroll frame and
clipped by another we keep track of that status with a
ClipAndScrollInfo.

The only piece of information about longhand SpecifiedValue types that
we don't have outside of the properties module is whether the types are
boxed or not. Provide that information in the
longhand_properties_idents macro so we can move
test_size_of_specified_values outside of the properties module.
CSS parsing optimizations
These address some small inefficiencies that showed up while profiling the myspace talos test.

BorderCornerRadius should always be non-negative, so we can implemennt
ToAnimatedValue for it directly, for properties:
1. border-{*}-radius
2. -moz-outline-{*}-radius
MozReview-Commit-ID: HEbeHz9Hfkd
We already have NonNegativeLength and NonNegativeAu, so we can re-use it
to define the specified value and the computed value of border-spacing.
And then implement ToAnimatedValue for it.
MozReview-Commit-ID: CLckpKMYVXU
Add NonNegativeLength, which could be computed to NonNegativeAu. So we
can declare Either<NonNegativeLength, X>, X=Auto, Normal, or Number.
NonNegativeLengthOrAuto is for column-width.
NonNegativeLengthOrNormal is for column-gap.
NonNegativeLengthOrNumber is for -moz-tab-size.
MozReview-Commit-ID: AfU8XpA1um0
Add values::computed::NonNegativeAu, so BorderSideWith could be computed
to this non-negative Au, for the following properties:
1. outline-width
2. border-{*}-width
3. column-rule-width
4. -webkit-text-stroke-width
MozReview-Commit-ID: ASHaB2F7VtM
NonNegativeNumber: for -moz-box-flex, flex-grow, and flex-shrink.
GreaterThanOrEqualToOneNumber: for stroke-miterlimit.
