This trades quite a bit of complicated code in Servo for few more
messages and a significant performance improvement. In particular,
WebRender can search the entire display list at once instead of
ping-ponging down the pipeline tree. This allows us to send mouse
events to the correct pipeline immediately.

http://www.robohornet.org gives a score of 101.36 on master, and 102.68 with this PR. The latter is slightly better, but probably within noise level. So it looks like this PR does not affect DOM performance.
This is expected since `Box::new` is defined as:
```rust
impl<T> Box<T> {
#[inline(always)]
pub fn new(x: T) -> Box<T> {
box x
}
}
```
With inlining, it should compile to the same as box syntax.

This type is a lot of complexity related to a very specific thing such as the
hover and active quirk.
Instead of that, move `nesting_level` to `MatchingContext`, and simplify all
this computing whether the quirk applies upfront, for each complex selector we
test.
This is less error-prone, and also allows simplifying more stuff in a bit.
Also, this makes the hover and active quirk work in Servo with no extra effort.

Casting `*const T` to `*const U` with `U: Sized` is allowed even if `T: ?Sized`. This safely extracts the data pointer out of a trait object, without relying on the memory representation of trait objects.

Currently `bound_texture_2d` and `bound_texture_cube_map` fields are used to restore texture states and to get the current bindings in GetParams(...). But as soon as active texture is changed all the values can become dirty, leading to broken textures in some demos or invalid getParam(...) call results.
This PR implements the texture binding association with the texture units.

Problems:
* the Heap::new constructor is memory-unsafe with any value other than Undefined/Null
* this means that moving dictionaries containing Heap values (ie. any/object) is memory-unsafe
* unions containing GC pointers are similarly unsafe
Solutions:
- dictionaries containing GC pointers are now wrapped in RootedTraceableBox (even inside other dictionaries)
- instead of using Heap::new, dictionaries containing GC pointers are now initialized to a default value (by deriving Default) and mutated one field at a time
- dictionaries containing GC pointers are marked #[must_root]
- FromJSVal for dictionaries containing GC pointers now returns RootedTraceableBox<Dictionary>
- unions wrap their variants that require rooting in RootedTraceableBox
Rather than attempting to derive Default for all dictionaries, we only do so for the dictionaries that require it. Because some dictionaries that require it inherit from dictionaries that do not, we need to write manual implementations for those parent dictionaries. This is a better option than having to figure out a default value for types like `Root<T>`, which would be required for deriving Default for all dictionaries.
I would still like to come up with an automated test for this, but I figured I would get eyes on this first.

<!-- Please describe your changes on the following line: -->
At the moment, layout panics if it discovers an iframe without a nested browsing context. Under normal circumstances, this is reasonable, but it requires very tight synchronization between script, layout, the constellation and the compositor. In particular, if a layout is in progress when an iframe's browsing context is discarded, this can trigger panic.
This PR fixes this in two ways:
1. Making the pipeline and browsing context ids optional in layout's representation of an iframe.
2. Shutting down layout before discarding a browsing context, rather than after.
This is belt and braces.
