All the other IFrame* names have the capital "I" and capital "F", so I'm changing this to keep uniformity.

After this patch, when the page calls `requestAnimationFrame()` too many
times in the row without actually mutating the DOM, further calls to
`rAF` will actually perform the moral equivalent of `setTimeout(16)`.
This saves a lot of CPU time compared to actually waiting for the
vertical blanking interval, because waiting for that requires us to draw
the page.
Reduces CPU usage drastically on nytimes.com, which has a perpetual
`requestAnimationFrame()` loop that checks whether ads are in view.

Implement XHR progress event changes
<!-- Please describe your changes on the following line: -->
This PR implements change in the specs in XHR.
Unfortunatelly, @jdm the test are not passing. It looks like the fetch module send more bytes that we should according the ```Content-Length```. This [lines](https://github.com/servo/servo/blob/master/tests/wpt/web-platform-tests/XMLHttpRequest/progress-events-response-data-gzip.htm#L70) make the test fail.

In support of this goal, the layout thread collects information about
CSS images that are missing image data and hands it off to the script
thread after layout completes. The script thread stores a list of
nodes that will need to be reflowed after the associated network
request is complete. The script thread ensures that the nodes are
not GCed while a request is ongoing, which the layout thread is
incapable of guaranteeing.
The image cache's API has also been redesigned in support of this
work. No network requests are made by the new image cache, since it
does not possess the document-specific information necessary to
initiate them. Instead, there is now a single, synchronous
query operation that optionally reserves a slot when a cache
entry for a URL cannot be found. This reserved slot is then
the responsibility of the queryer to populate with the contents
of the network response for the URL once it is complete. Any
subsequent queries for the same URL will be informed that the
response is pending until that occurs.
The changes to layout also remove the synchronous image loading
code path, which means that reftests now test the same code
that non-test binaries execute. The decision to take a screenshot
now considers whether there are any outstanding image
requests for layout in order to avoid intermittent failures in
reftests that use CSS images.
