+ HLS resources with remote subresources will not taint canvasses.

+ Source/WebCore:
+
+ Test: http/tests/security/canvas-remote-read-remote-video-hls.html
+
+ Most media sources are single-resource; they are accessed from a single origin. HLS manifests can contain many
+ subresources from arbitrary origins, and canvases should be tainted when painted from media elements whose
+ subresources were retrieved from tainting origins.
+
+ Add a new method to HTMLMediaElement, wouldTaintOrigin(), taking a SecurityOrigin, and returning whether the
+ media element would taint that origin. This gets piped all the way down to MediaPlayerPrivateAVFoundationObjC
+ which uses WebCoreNSURLSession to track all the origins of all the responses which resulted from the media
+ element's load.
+
+ Drive-by fix: also fix this issue for media elements which render to an AudioContext.
+
+ Drive-by fix #2: CanvasRenderingContext2DBase::createPattern() needs to check the return value of
+ ImageBuffer::create() before using it.
