Add origin-clean flag tracking for canvas
The resulting failures are because we aren't doing origin-comparison correctly (I bet the image ends up with an empty hostname or something). We could probably hack around that if we care, but it should just go away when we get the origin checking right.

Browser API: implement iframe.reload()
fixes#8575
The implementation is naive, and doesn't support the `hardreload` parameter.
And for the test, I'm not sure how else I can test the reload.

Add test to constellation to avoid writing reftest image if there are pending frames.
This changes several tests that contain <iframe></iframe> from FAIL to TIMEOUT. This is correct
since there is a bug that prevents these iframes from ever rendering.
~~~There are also a few previous FAILs that changed to OK. These may be intermittents or they
may genuinely be fixed by this change.~~~

Optimize `TextRun::advance_for_range`.
The combined effects of these optimizations move `advance_for_range` from #1 in the layout profile on all sites I tested to #2, #3, or #4, depending on the site.

Add pinch zoom gesture for touch-screen devices
r? @glennw
Notes:
* Our layer system doesn't yet support zooming `<iframe mozbrowser>` separately, so this can only zoom the root window.
* There are some issues that cause some tiles to disappear while zooming. I hope this will be fixed by WebRender.
* Sorry this is mostly in one giant commit. I did the refactoring and adding new functionality in tandem, and didn't really end up with logical or compilable intermediate commits. Hopefully the new code is easier to read than the old stuff.

Also change when pipelines become active.
This makes the constellation activate a pipeline as the current frame
when it is ready to do initial reflow, rather than when it is ready
to paint.
This fixes a number of intermittent failures that could previously occur
if an iframe was not visible - which would mean it was never moved from
a pending frame in the constellation to an active frame.
(It happens that webrender exposes these intermittents as permanent failures).
Implement basic framework for static and interactive validation on forms
This came along when I was trying to do #3648. I was about to do form validation as well, but then I saw it was actually intended to be a student project. Hopefully I didn't step on too many toes on this one; I did leave most of the important bits out (the fun bits I believe, e.g. interactive validation doesn't actually interactively validate anything right now).
