always call new_pipeline() before add_pending_changes()
There are some changes we want to make in `add_pending_changes` which require pipelines to be registered in self.pipelines.

Don't update iframe pipeline until load completes
To preserve the previous functionality of delaying load events when a
new navigation is triggered, pending pipeline id represents the
current pending load. The load event is only fired if the load message's
pipeline id matches the pending pipeline id.
Track frame size on Frame instead of Pipeline
Disabled matchMedia test
Track creator pipeline id
Notify embedder when history changes
`WindowMethods::set_page_url` is only called when the embedder set the URL. It is not called when the page url is updated. I believe that instead we should just pass the URL to `head_parsed`.

Just use WebRender's ClipId directly. This will allow us to create and
use ReferenceFrames in the future, if we need to do that. It will also
make it easier to have Servo responsible for creating the root
scrolling area, which will allow removing some old hacks in the future.

Frames in the constellation store LoadData rather than just URLs.
<!-- Please describe your changes on the following line: -->
Include LoadData in each session history entry, so that when we reload discarded documents we can include POST data etc.
