This is what was making me hit the new test failures. So turns out that when the
DOMContentLoaded event is fired we fired no messages to the constellation, but
we fired the DOMLoad message from the DocumentProgressHandler, effectively after
having dispatched the Load message from script thread.
This also fixes the possibility of a subframe navigation not blocking the load
event of the parent document, for example.
This is a rewrite for how style interfaces with its consumers in order to allow
different representations for an element snapshot.
This also changes the requirements of an element snapshot, requiring them to
only implement MatchAttr, instead of MatchAttrGeneric. This is important for
stylo since implementing MatchAttrGeneric is way more difficult for us given the
atom limitations. This also allows for more performant implementations in the
Gecko side of things.

Issue 8719: Add basic support for :active selector
<!-- Please describe your changes on the following line: -->
Added toggling of active state for element and parents on mousedown/mouseup. Active state is removed when mouseout. (hover)
- As with my other PR i'm struggling a bit with the automated testing. I've added a manual test case and found quirks-mode/active-and-hover-manual.html which - aside from also being a manual test, is functional in Firefox but does not render correctly in Servo.
- Not implemented: In Firefox, behaviour differs with a <!DOCTYPE HTML> and an anchor does not lose it's activation on mouseout; whereas a button does.

Replace return_address usage for rooting with stack guards and convenience macros.
The existing `Rooted` and `RootedVec` users were migrated the the following two macros:
```rust
let x = Rooted::new(cx, value);
// Was changed to:
rooted!(in(cx) let x = value);
// Which expands to:
let mut __root = Rooted::new_unrooted(value);
let x = RootedGuard::new(cx, &mut __root);
```
```rust
let mut v = RootedVec::new();
v.extend(iterator);
// Was changed to:
rooted_vec!(let v <- iterator);
// Which expands to:
let mut __root = RootableVec::new();
let v = RootedVec::new(&mut __root, iterator);
```
The `rooted!` macro depends on servo/rust-mozjs#272.
These APIs based on two types, a container to be rooted and a rooting guard, allow implementing both `Rooted`-style rooting and `Traceable`-based rooting in stable Rust, without abusing `return_address`.
Such macros may have been tried before, but in 1.9 their hygiene is broken, they work only since 1.10.
Sadly, `Rooted` is a FFI type and completely exposed, so I cannot prevent anyone from creating their own, although all fields but the value get overwritten by `RootedGuard::new` anyway.
`RootableVec` OTOH is *guaranteed* to be empty when not rooted, which makes it harmless AFAICT.
By fixing rust-lang/rust#34227, this PR enables Servo to build with `-Zorbit`.
