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

style: Less ID revalidation selectors.
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.

style: Prevent cousin sharing if we haven't restyled the parents.
This "fixes" bug 1381821 by disabling the optimization in the cases we can't
prove this is correct. Bug 1387116 tracks fixing the optimization to apply more
broadly.

Fix warning in scroll root id assignment to TableColGroupFlow
The traversal currently expects every flow to have a scroll root id
assigned, even if it doesn't produce any display items. This change
fixes the error that arises from this situation.

style: Move nsStyleContext::mParent to GeckoStyleContext.
Unfortunately this means that we lose the NS_STYLE_INHERIT_BIT optimization to
avoid posting changes if we had not requested the struct. In practice, I'm not
sure this optimization matters much, though, and we already compare all the
structs anyway.
We _could_ keep a weak parent pointer from the text style if needed, given we're
going to keep alive the text style at least until the parent style context goes
away, so should be safe, but I don't think the extra churn is worth it, to be
honest. Happy to do so as part of bug 1368290 if you think it's worth it.
