Use whether we've computed any viewport unit instead.
This is more accurate (we avoid restyling unnecessarily if we've found anything
ever on the stylesheet, but that hasn't matched).
This has the benefit of also matching Gecko, and simplify some code and
fishyness around, and also hopefully speeding up stylesheet parsing.
Currently, Servo uses ComputeSquaredDistance derive for
SvgLengthOrPercentageOrNumber, so servo can't calculate between
LengthOrPercentage and Number.
This PR will allow calculating these value.
Introduce ComputedUrl
<!-- Please describe your changes on the following line: -->
Use the new `ComputedUrl` type for computed types and `SpecifiedUrl` for specified types instead of using the `SpecifiedUrl` implementation for both.

As silly as it may seem to specify font-sizes using viewport units, we weren't
handling zoom for them correctly either.
Bug: 1388588
Reviewed-by: Manishearth
MozReview-Commit-ID: 3Q6phYAu5CE
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.

The concept of inherited style is about to get a bit more complicated, and this
will prevent consumers from doing it wrong.
Part 1 of Gecko bug1382806. r=emilio
Sync Servo / Gecko image-orientation rounding; pass as enum.
Make Servo's rounding of image-orientation values agree with Gecko's,
and pass orientations directly as an enum instead of as angles.
Depends on a Gecko change to be subsequently landed in m-c.

It was storing both TrackSize and TrackRepeat before and TrackRepeat have to be
converted into sequence of TrackSize during serialization. Instead of doing this
in serialization process(which is hard and hacky), we converted to do this in
parsing process. We were doing this conversion in the ComputedValue conversion.
So we only had to move this process to parsing.

Add support for subgrids and fix some other grid properties
This covers the `subgrid <line-name-lists>?` for `grid-template` (for gecko, and hence, stylo).
