This avoids grabbing the document when values that inherit from the body,
whatever that means, aren't under the body.
In that case we'll get a semi-random value, but that's also mishandled by Gecko
anyways (and probably Blink, though haven't tested), and doesn't really make
much sense.
Preserve sourceURL comment on style sheets
In addition to the sourceMappingURL comment, there is a second special
comment, "sourceURL", that can be used to set the "display name" of a
style sheet for developer tools. This name is also used as the base
URL for the source-map URL resolution algorithm. sourceURL is
described here:
https://blog.getfirebug.com/2009/08/11/give-your-eval-a-name-with-sourceurl/
The devtools feature bug is here:
https://bugzilla.mozilla.org/show_bug.cgi?id=880831
This patch changes servo to preserve and expose this value for use in M-C.

Share specified URLs with Gecko
This makes use of our Arc offset machinery to allow Gecko to store Arc<String> values and ensure there are used appropriately.

We have about 11,500 of these when loading gmail in a Stylo-enabled build, from
SpecifiedUrls; the objects themselves account for about 1.3 MiB of memory, and
the strings within them about 2.9 MiB.
We also have a very small number of them on the Gecko side.
style: Add system colors from bug 1387594.

These are the necessary servo changes for https://bugzilla.mozilla.org/show_bug.cgi?id=1387594 .
I'm also re-importing the generated Gecko bindings from my object directory:
- servo/components/style/gecko/generated/structs_debug.rs
- servo/components/style/gecko/generated/structs_release.rs
But the number of changes to those files surprises me.

More codesize reductions for generated code
Bloaty says this shaves off another 20kb from style::properties-based functions. The more limited Debug implementations enable sharing the property name strings between more functions, which saves on code size in the end.

Use exhaustive match for cloning keyword value by default for property using enum class
rather than casting them to `u8` then do inexhaustive match.
I don't see why we couldn't do this.

style: Don't cache styles that got a cache hit on the second pass.
This avoids doing wasted work, at least in the recascade case, and pretty likely
in the other as well.

Rule cache
<!-- Please describe your changes on the following line: -->
This adds a TLS-based cache reset styles structs keyed off rule nodes. Reviewed in https://bugzilla.mozilla.org/show_bug.cgi?id=1367635 by me and Emilio.
