from my point of view, output hotplug is always a pain to test on DRM,
so I would appreciate help with that. This kind of cases:

- on a running compositor, add an output with hotplug
- on a running compositor, remove an output with hot-unplug
- hot-unplug all outputs, the compositor should remain running
- after hot-unplugging all outputs, plug them back in
- start the compositor without any outputs, then hotplug some
- hotplug/unplug tests with MST, so that we have DRM connectors
  appearing and disappearing

At all times, weston-info should reflect the actual number of outputs,

All the cases could be taken further by hotplugging and hot-unplugging
while VT-switched away. It is also possible that some of this is
already broken in upstream master, so if you encounter failures, it
would be good to know if it was already broken.

Those are my wishes, Daniel probably has others. Any testing reports
at all would be awesome.
