Switch FreeBSD CURRENT to use the new xorg stack (WITH_NEW_XORG=) 
If the old xorg stack is still needed, it is possible to add WITHOUT_NEW_XORG=
to /etc/make.conf to get the old version.
Update several xorg related ports, including:
x11/libxcb 1.9.1 -> 1.9.3
graphics/libdrm 2.4.46 -> 2.4.50
x11/pixman 0.30.2 -> 0.32.4
x11/xkeyboard-config 2.9 -> 2.10.1
x11-drivers/xf86-input-keyboard 1.7.0 -> 1.8.0
Fix dissapearing cursor in xf86-video-vmware 
Stagify all x11@-owned ports
Bump portrevisions for xf86-* ports due to xserver version change.
Fix fallout from updates where needed.
