Bug 1147 - Fix XRandR13 Usage: Rotate / Change-Mode, use unique CRTC/Mode ids, ..

RandR 1.3 XRRSetCrtcConfig related:

- X11RandR13 now sets the new screen size via XRRSetScreenSize(..)

- X11RandR13 now propagates RRScreenChangeNotify events
  via XRRUpdateConfiguration(event).
  Hence reporting virtual desktop size now.

- X11RandR13 now disables the CRTC before XRRSetCrtcConfig(..)
  to avoid invalid configuration (see spec)!

RandR 1.3 General:

- Uses unique id named instead of unstable index
  for modes and CRTC.
  This allows proper identification even for 'swizzled' devices.
