orientation, but should use any image orientation provided by the image.

If we just update the document pointer and not the inner window id then the request is unusable by any document since both the inner window id and the document pointer must match for it to be re-usable.

ReferrerPolicy gets tossed back and forth as a uint32_t and
ReferrerPolicy enum in header file. Expose ReferrerPolicyValues from
webidl file and use consistently in native code.

This was observed in an intermittent failure of image/test/mochitest/test_discardAnimatedImage.html. What happened was:
1) Document::MaybePreLoadImage was called for the images in the test.
2) imgRequest::OnDataAvailable is called on at least one of the images. This creates the RasterImage, so any proxy for this imgRequest will now return the image via GetImage(). imgRequest::OnDataAvailable also queues the FinishPreparingForNewPartRunnable back to the main thread to call OnImageAvailable on the progress tracker on the main thread.
3) We get the actual LoadImage calls for the images of the document. We create new proxies for the existing imgRequests. imgRequestProxy::Init calls mBehaviour->SetOwner(aOwner), which sets mOwnerHasImage to true because the progress tracker has an mImage (the one we created above).
4) We get a call to LockImage, this gets forwarded to the RasterImage because mOwnerHasImage is true and we can access the image.
5) The FinishPreparingForNewPartRunnable finally runs on the main thread. The OnImageAvailable notification from the progress tracker ends up in imgRequestProxy::SetHasImage. imgRequestProxy::SetHasImage applies our local count mLockCount to the RasterImage, even though we've already forwarded one of those LockImage calls to the image. LockImage calls are now unbalanced and the image will always remain locked.
The fix is simple. Only apply the Lock/Unlock calls if the FinishPreparingForNewPartRunnable has hit the main thread (ie ignore an image we can access until this happens).

This removes an unnecessary level of indirection by replacing all
nsStringGlue.h instances with just nsString.h.

The "current URL" in the spec:
https://html.spec.whatwg.org/multipage/embedded-content.html#dom-img-currentsrc
maps to imgIRequest.URI, not currentURI.
Rename imgIRequest.currentURI to finalURI to prevent such confusion.

The imgLoader code consistently uses the term 'loadingPrincipal' for the
principal that is called the triggeringPrincipal everywhere else it's used.
This is confusing, and since we need to make changes to how those values are
determined, it should be fixed beforehand.

Currently we only permit requests from HTTP channels to be retargeted to
the image IO thread. It was implemented this way originally in bug
867755 but it does not appear there was a specific reason for that.
The only kink in this is some browser chrome mochitests listen on debug
build only events to ensure certain chrome images are loaded and/or
drawn. As such, this patch ensures that those observer notifications
continue to be served, requiring a dispatch from the image IO thread to
the main thread.
Another issue to note is that SVGs must be processed on the main thread;
the underlying SVG document can only be accessed from it. We enforce
this by checking the content type. The possibility already exists that
an HTTP response could contain the wrong content type, and in that case,
we fail to decode the image, as there is no content sniffing support for
SVG. Thus there should be no additional risk taken by using the image IO
thread from other non-HTTP channels (if they don't specify the SVG
content type, it is not rendered today, and if they do, it will remain
on the main thread as it is today).
We also ignore data URIs. The specification requires that we process
these images sychronously. See bug 1325080 for details.
