Two main notes:
* The nsStringBuffer bit goes untested, since it's only used on windows and
there's no way I can test it, please review with care.
* I haven't implemented yet the "enumerated" media queries. I'd want to do it
as a follow-up, because I'm running out of time, and it requires some
investigation.

The setup is quite different to Servo-land, so add a comment about the different
setup.
Also, check viewport rules when flushing stylesheets. I believe that the
previous behavior is plain wrong, though I haven't taken the time to come up
with a test case.
In any case, it doesn't hurt any of both back-ends.
