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.
