There are still some issues I need to figure out, essentially: 1. I'm not covering all the cases from D208467. Actually I'm not sure how to reach some stuff like xslt, worker or track... 2. My patches forward the (default) internal priority from the first request and then adjust that priority again in FetchDriver.cpp. That's correct for images, but not in other cases (e.g. using link_preload_script adjustments on top of a script loaded from the head gives wrong expectations).

The image tests seem to be flaky for some reason.
