The attached patch against the git refpolicy from 3 days ago makes Chrome work
with Pulseaudio, DRI, Flash, and lots of little things.
Adds tunables chromium_exec_plugins and xserver_allow_dri.
I think this is ready to merge with the names of the tunables and interfaces
being the only possible changes needed.
