Upgrade to rustc 1.21.0-nightly (7eeac1b81 2017-08-30)
Fix this error in the new Rust Nightly:
```rust
Compiling script v0.0.1 (file:///home/simon/servo2/components/script)
error[E0599]: no method named `trace` found for type `&fn(&dom::node::Node) -> u16` in the current scope
--> /home/simon/servo2/components/script/dom/treewalker.rs:464:10

464 | #[derive(JSTraceable)]
| ^^^^^^^^^^^

= note: JSTraceable is a function, perhaps you wish to call it
= help: items from traits can only be used if the trait is implemented and in scope
= note: the following trait defines an item `trace`, perhaps you need to implement it:
candidate #1: `dom::bindings::trace::JSTraceable`
error: aborting due to previous error
error: Could not compile `script`.
```
~I’ve tried to reproduce it in a minimal test case, but `impl<A, B> SomeTrait for fn(A) -> B` did not apply for `fn(&u32) -> u32` even on Rust 1.19.0 stable. So I don’t know what changed.~ This is very likely https://github.com/servo/servo/pull/18327.

Fails for unrelated reason when building `servo-skia`.

Make the order of rules in DevTools be the specificity order.
We insert rules with any important declaration into rule tree twice,
one for the normal level and another for the important level. And
when we fetch them from rule tree, we skip the important one to
make the order be the specificity order.

Update WR (font instance API).
WR now has a concept of font templates and font instances. This
makes the WR font interfaces closer to Cairo and Gecko, and also
makes some future performance optimizations possible.
A font template is the font family, and data backing the font.
A font instance is a reference to a font template and per-instance
options, such as font size, anti-aliasing settings etc.
To update Servo in a minimally invasive way, I added a new font
cache call, that creates a font instance. This means that when
a font is created, and doesn't exist in the cache there are now
two calls to the font cache thread. We could refactor the font
cache to make this work in one call, which we should do in the
future. However, refactoring the font cache is a large chunk of
work by itself. The extra call is only when a font doesn't already
exist in the font context cache, so it should have minimal
performance impact.

It also splits rust-webvr traits to a separate crate. This allows much faster compilations when using local cargo replaces.

Harden assert for creating atom from raw pointer
One of Stylo's common assertion turns out to be from having a null Atom (see [Gecko 1385925 bug comment 7](https://bugzilla.mozilla.org/show_bug.cgi?id=1385925#c7)). It would be helpful if we can catch this kind of crash earlier via a release-assertion.
This may regress performance to some extent which I'm not sure. But we can probably have it there for diagnosis for now, and remove later.
