Now that we do process normal traversal even in the case of throttled animation
flush so that we don't need to do special handling for the case.
Note about the comment in has_current_styles():
the remaining animation hints is not caused by either this patch or the
previous patch in this patch series, it's been there in the first place, but
it should be fixed somehow later. See bug 1389675.

Deduplicating code is nice, and it will help us when we make the bit
propagation more complicated in upcoming patches.

The buggy animation handling isn't a regression, since currently we pass
UnstyledChildrenOnly in those cases, which blocks the animation traversal
in Servo_TraverseSubtree.
In general I really wanted to handle these two paths together. But there's
enough broken with the NewChildren path that I wanted to scope the buginess
as tightly as possible. And I really need to separate the handling here from
StyleDocument() to make the restyle root stuff work.

Doing anything else is non-sensical, since we're not guaranteed to reach all of
the bits from traversal Y when doing traversal X.

Using namespace id fixes this issue because in Gecko, the pref of MathML
(as well as SVG) works in the way that we choose a different namespace
id (the disabled id) for the elements. Those ids are mapped to the same
namespace atom as normal ids, which means if we use the atom, we would
treat the elements like normal mathml elements.
Introduce ComputedUrl
<!-- Please describe your changes on the following line: -->
Use the new `ComputedUrl` type for computed types and `SpecifiedUrl` for specified types instead of using the `SpecifiedUrl` implementation for both.
