This Root<T> relies on the concept of a stable trace object, which doesn't
move for the whole lifetime of the T value. For safety reasons, T must be 'static.
The only implementor of StableTraceObject for now is Dom<T>.
<applet> is not a thing anymore, and that selector in our UA sheet will never
match anyway, since an <applet> element will never have the BROKEN state.

We were using the wrong MatchingMode and flags setter just because we didn't
bother threading them down.
This patch fixes the issue seen with the video controls.

This could prevent an XBL binding to use some pseudo-elements fairly randomly.

nsString bindings update
<!-- Please describe your changes on the following line: -->
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.
