"javascript:" urls: execute in correct global scope
<!-- Please describe your changes on the following line: -->
#### Summary
This pull request makes `javascript:` urls execute in the correct global scope.
#### Example
```html
<script> var x = 4; </script>
<!-- this branch: logs "4" -->
<!-- master: undefined variable error -->
<a href="javascript:console.log(x)">link</a>
```
#### Questions
I'm new to servo and rust, so I'm unsure about these changes. In particular:
* What's the appropriate place to evaluate the js?
* I moved it to `handle_navigate`, but I'm not sure if this will catch all occurrences of `javascript:` urls. I also don't know if this will execute in the correct thread and the correct window.
* What should I do with the result of the js evaluation?
* I just ignored it. The previous behavior displayed it as the content of a new page load.

The given argument may have special meaning for the element to which we add it,
and thus may have a specific representation to which we should switch the
attribute current's value.
Fixes#18357.
* Update rust-azure to 0.21.0
* Mark the following test case as fail:
tests/wpt/mozilla/tests/mozilla/css-paint-api/background-image-tiled.html
* Make the ellipse test case pass.
BUG: https://github.com/servo/servo/issues/17598
Upgrade to rustc 1.21.0-nightly (7eeac1b81 2017-08-30)
Fix this error in the new Rust Nightly:

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

= 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.

- generalize the eval_js_url function so it can be called from
multiple places.
- call it in htmliframeelement.
- if the js eval results in a non-string result, then it won't
navigate to a new page, so don't block on the new page loading.

style: Don't look for viewport units in stylesheets.
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.

PerformanceObserverInit.buffered
Per #18108, add `buffered` flag in the `PerformanceObserverInit` dict.
Per W3C spec, when `buffered` is set, `PerformanceObserver.observe()` method adds the entries buffered in the `Performance` instance into the observer's entry buffer.
One step is the implementation of the [filter by name and type](https://w3c.github.io/performance-timeline/#filter-buffer-by-name-and-type) algorithm. Don't think that the sort operation is useful in this case, but the spec states that this algorithm is to be used.
