Don't create a new XHR until the previous one is complete.
This test often times out when run under rr, because the event loop gets flooded with timer events that initiate XHRs before the previous XHR has completed. Additionally, we're running the event handler up to three times per XHR, which is just silly.

It's a bit unfortunate the use separate implementations of SpecifiedUrl for Servo
and Gecko, but they're different enough at this point that I don't think it really
makes sense to try to share everything. Splitting them out has some nice
simplifications as well.
I recognize that there's still some potential correctness issues for Servo using
the resolved URI in various places where the original URI may be the right thing,
but I've got too much on my plate to look into that for now.

Now that WebRender can handle splitting scrolling layers on its own, we
don't need to do any work to split up scroll roots. This should also
make it possible to handle overflow:scroll and containing block scroll
roots in the future.
