Implement non-visible pipeline and iframe visibility methods
This addresses #9566 and a good part of #9751, specifically:
* Pipeline has a notion of visibility
* IFrame setVisible/getVisible interface with IFrame's pipeline visibility
* IFrame mozbrowservisibilitychange responds to changes in visibility
* Pipeline visibility is used to limit animations (requestAnimationFrame does not tick animations when hidden) and to increase timer intervals (currently set to a minimum of 1 second while hidden)
Absent for now are any changes to the Document API and general implementation of the Page Visibility API, since the more interesting parts require knowledge of whether the user agent is minimized, OS screen locked, etc.

Avoid deadlock when closing a pipeline.

At the moment, the constellation blocks on a pipeline during closure. This PR makes pipeline closure asynchronous.

WebRender.
This happens asynchronously, just as it does in non-WebRender mode.
This functionality is a prerequisite for doing proper display-list-based
hit testing in WebRender, since it moves the scroll offsets into Servo
(and, specifically, into the script thread, enabling iframe event
forwarding) instead of keeping them private to WebRender.
Requires servo/webrender_traits#55 and servo/webrender#277.
Partially addresses #11108.
The previous code assumed that the diagonals of the elements were
perpendicular, which only happens with squares.
tests: layout: Test linear gradient corners
Support controlling interface and member visibility via preferences
This was easier to throw together than per-attribute/method support, and it gets rid of some nonstandard properties from our globals.
Fixes#7626.

script: Make iframes know their pipeline IDs at all times, even after navigation.
Since WebRender uses the pipeline ID stored in the iframe element to
determine which pipeline to display, it had better be kept up to date!
Closes#9919.

webgl: Implement the pending texImage2D overload, and add more validation
This is a large-ish refactor of the Texture2D code, but it should be
easier to read and of course more correct.
I tried to annotate every error condition with a spec paragraph.
I made just a reftest to ensure this works as intended, since I expect #10373 to land pretty soon.
