xf86SetSingleMode tries to resize all crtcs to match the selected mode. When
a CRTC has no matching mode, it now disables the CRTC (instead of crashing).
Also, poke the RandR extension when xf86SetSingleMode is done so that
appropriate events can be delivered, and so that future RandR queries return
correct information.
