I doubt that there is a big timing impact between sharing named drm handles
and prime fds, but yeah right now neither is supported. And we need that
for mir and wayland. I believe dma_bufs are the nicest way to share buffers
across processes., so I added them first and made sure they work on qxl. I
still wanted to do a test run with wayland on qxl, so far I only verified
that mir works.

Additionally I think that we could get rid of the 'can_share_buffers' logic
here and there, since the generic flink - ioctl comes with gem and is hence
supported by the interesting 'software'-drm drivers like udl.

But right now I was hunting down some graphical artifacts in swrast.

regards
Andreas
