Jon Turney c1eb12f89c xwin: Update to XRANDR 1.2 internal interface to ensure an output is reported by XRANDR 
If using the X server internal XRANDR 1.0 interface, it seems we must
register a display size with RRRegisterSize() in order to make
RRGetInfo() call RRScanOldConfig() to generate an output and crtc for
us.

Without this, the following GDM bug means that an XDMCP session to GDM
cannot be started.

https://bugzilla.gnome.org/show_bug.cgi?id=736054

Instead, use the more recent XRANDR 1.2 internal interface to explicitly
create the output and crtc, and maintain a single mode which represents
the current display size.

Also don't emit a RRScreenSizeNotify when a RRScreenSizeSize is done
which has no effect, this seems to throw the GDM greeter into a loop...

v2: Maintain reference count for the mode we maintain more correctly, to
avoid double free causing a crash on shutdown

Connect crtc to output, so a subsequent RRSetCrtcConfig request doesn't
change anything, so we don't fail due to our lack of rrSetConfig or
rrCrtcSet hooks.

See https://cygwin.com/ml/cygwin-xfree/2015-02/msg00032.html

v3:
Raise limit on X display size from 4Kx4K to 32Kx32K

					X Server

The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.

Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.

For a comprehensive overview of X Server and X Window System, consult the
following article:
http://en.wikipedia.org/wiki/X_server

All questions regarding this software should be directed at the
Xorg mailing list:
