It's not ugly. It's actually the correct fix to ensure that there is
only one winsys & screen per device per process. Our GL and VDPAU
drivers do it too and initially it was the only way to share
pipe_resource between libs. It's also done by nouveau and freedreno.
The idea is that first loaded lib exports the whole gallium driver via
these symbols and any libs loaded later are forced to use it and can't
use their own.
