I will use this soon to implement the media query evaluation code.
Please review carefully.

The getter function may create an nsCSSValue with allocated stuff, and we don't
want to leak it.

The setup is quite different to Servo-land, so add a comment about the different
setup.
Also, check viewport rules when flushing stylesheets. I believe that the
previous behavior is plain wrong, though I haven't taken the time to come up
with a test case.
In any case, it doesn't hurt any of both back-ends.

Cleaning up CalcLengthOrPercentage
<!-- Please describe your changes on the following line: -->
We don't really need enum variants in `CalcLengthOrPercentage`. Given that we already have the information (whether it's `vw`, `ch`, etc.) in the struct fields, we could just store `Option<CSSFloat>` there, and modify our `ToCss` implementation a bit.

gfx: Don't mutate the same point multiple times while translating it …
…to other stacking context space.
I don't know how neither review or a test caught this.

Bug 1331272: style: Unify restyle-damage display: none checks.
They were formerly different because we used the element check to cull the
traversal.
Now this is no longer true, so we can just unify them.
Also, update a no-longer up-to-date comment on that.

Do not use the script element's line number for external scripts.
This was yielding incorrect line numbers when looking at JS backtraces in gdb.

Make WebIDL callbacks permanently rooted
This replicates the same model that Promise uses right now, because it requires less thinking than coming up with something else.

Store blink value for text-decoration-line
The spec does say user agents may not blink, but it doesn't say this

Enable codegen-units=4 in debug mode
We previously had this and removed it because it caused runtime slowdowns
(discussion in #11102), but that was in release mode.
Debug mode is already very slow at runtime.
In my opinion, debug mode is mostly for the edit-compile-test cycle
which is currently dominated by compile times, so sacrificing runtime for compile time makes sense.
I’ve observed a ~30% improvement of compile times with this. This figure is consistent between a very fast desktop with 4 cores / 8 threads and a not-as-fast laptop with 2 cores / 4 threads.
