So, I've pushed the crash fix, but not the state resetting thing.  After
testing it, it seems xrandr gets very upset (even just running xrandr
--verbose) with CRTCs disappearing (although this is probably valid behaviour)
and dies with a fatal error of "cannot find crtc 0x..", so I'll stick with the
crap lingering CRTC behaviour, rather than break xrandr whenever someone
disconnects an output.

As for bailing out at modeset time, yes, this might be possible, but it relies
on the xserver failing gracefully, and the user app coping with a failure for
which it can determine no good reason, which I think is a higher standard to
expect than getting the application to query what display is connected before
it sets out on its modesetting journey.

Happy for this bug to be resolved as fixed?
