[PATCH xserver 0/7] modesetting - more stable MST hotpluging

[Daniel Martin]

This patchset handles hotpluging of MST connectors. They can be fun,
especially if we aren't active (VT switched away) and vanish + reappear.

- We have to check for uevents on EnterVT, otherwise we may work with
  outdated output_ids leading to a failing drmmode_set_mode_major() and
  tear the server down.
- We have to compare the PATH if available, as the output_id is
  unreliable.
- We have to make sure, we don't throw zero outputs to configure into
  drmModeSetCrtc() as this will fail and tear down the server.

Thanks,
    Daniel
