qxl: add a connector property to denote hotplug should rescan modes.
So GNOME userspace has an issue with when it rescans for modes on hotplug
events, if the monitor has no EDID it assumes that nothing has changed on
EDID as with real hw we'd never have new modes without a new EDID, and they
kind off rely on the behaviour now, however with virtual GPUs we would
like to rescan the modes and get a new preferred mode on hotplug events
to handle dynamic guest resizing (where you resize the host window and the
guest resizes with it).
This is a simple property we can make userspace watch for to trigger new
behaviour based on it, and can be used to replaced EDID hacks in virtual
drivers.

drm: delay minor destruction to drm_dev_free()
Instead of freeing minors in drm_dev_unregister(), we only unplug them and
delay the free to drm_dev_free(). Note that if drm_dev_register() has
never been called, minors are NULL and this has no effect.
This change is needed to allow early device unregistration. If we want to
call drm_dev_unregister() on live devices, we need to guarantee that
minors are still valid (but unplugged). This way, any open file can still
access file_priv->minor->dev to get the DRM device. However, the minor is
unplugged so no new users can occur.

Don't delay minor removal to drm_put_minor(). Otherwise, user-space can

drm: eliminate bit-copy restoration of crtc
Bit-copying restoration of CRTC structure in failure-recovery
path of drm_crtc_helper_set_config function evokes a
subtle and rare, but very dangerous, corruption of
CRTC mutex structure.
Namely, if drm_crtc_helper_set_config takes the path under
'fail:' label *and* some other process has attempted to
grab the crtc mutex (and got blocked), restoring the CRTC
structure by bit-copying it will overwrite the CRTC mutex
state and the waiters list pointer within the mutex structure.
Consequently the blocked process will never be scheduled.
This patch fixes the issue by eliminating the bit-copy
restoration. The elimination is possible because previous
patches have cleaned up the resoration path so that only
the fields touched by the drm_crtc_helper_set_config function
are saved and restored if necessary.
