I think this patch is functionally neutral. I'm not completely sure about the best way to do these casts - the __bridge may not be necessary since we don't use ARC yet. But it's probably fine to add it anyway. Also, returning autoreleased CFTypeRef objects seems a bit weird, but it's what we've already been doing and it's probably fine. And some of these nils should maybe be nullptrs, but the compiler doesn't seem to care. Differential Revision: https://phabricator.services.mozilla.com/D129559
