This fixes bugzilla bug [1403170](https://bugzilla.mozilla.org/show_bug.cgi?id=1403170).
We've missed a few updates of the nsstring bindings in servo compared to the changes in gecko, so we really ought to find a better solution than these manual updates. For example, recently the way flags in nsstring are implemented was completely redone, and this version wasn't updated. It happened to be that the representation of the new form was identical to the old one, so it wasn't a problem, but technically this was wrong.

Removed Step 30.2 which raised a JS TypeError if the integrity metadata was not empty. I manually ran `new Request("", {"mode" : "no-cors", "integrity" : "not an empty string"});` in servo to validate that the exception no longer arose.

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.

…ic atom for will-change.
If we don't increment the reference count for the Atom in servo side, it's
possible to try to release the Atom in servo side even if we have already
released in gecko side. When it happens, nsIAtom::mKind is no longer reliable.

At present, we do the fallback discrete animation for non-invertible matrices in
ComputedMatrix.animate(). However, according to the spec, we should fallback to
discrete animation for cases like:
1. animation between transform with single non-invertible matrix
2. animation between transform with matched transform functions that have at least
one non-invertible matrix
2. animation between transform with mismatched transform functions that have at
least one non-invertible matrix.
The current implementation only handles the first case.
Moreover, we already have fallback discrete animation procedures in CSS Animation
and Web Animation, so we should be able to not doing any fallback inside the
Animate trait.
In this patch, we let the animation between non-invertible matrices to return Err().
So, we can propagate the Err() to the callers, and let the fallback discrete
animation procedure stay at the Servo_MatrixTransform_Operate, which is ouside
the Animate trait.

TypedSize2D's MallocSizeOf impl has two problems.
- It measures `width` twice, and `height` not at all.
- It erroneously asserts that `width` and `height` are scalars. This
seems reasonable at first blush, but Stylo uses
`BorderRadius<LengthAndPercentage>` which contains a
`TypedSize2D<LengthAndPercentage, UnknownUnit>`, and
`LengthAndPercentage` is non-scalar.
This patch fixes both of these problems, and also removes a low-value
`use` statement.

Over in [bug 1398393](https://bugzilla.mozilla.org/show_bug.cgi?id=1398393), I found that when we turn Quantum DOM's cooperative threads on, we hit a Servo panic because we assume that we've set some state in the TLD. The cooperative threads currently have no way of doing this without also re-initializing the log module and some other static data. This small patch gives the cooperative threads a way of informing Servo about themselves.
