CFT: update Xorg to 1.19.3

[Jan Kokemüller]

Thanks, Xorg 1.19.3 from your patch works great for me. I've had trouble 
applying the patch, though. There were conflicts in the devd backend. I 
used "patch < Xorg_1_19_3.patch" to apply the patch. I've been running 
the libdevd-udev backend for now.

I'm running the 'modesetting' video driver on Intel Sandybridge graphics 
and it works without tearing when using compton. It seems a good 
alternative to the xf86-video-intel driver.

Evdev devices are picked up correctly by the libdevd-udev backend. But 
there is a small bug uncovered by using evdev devices exclusively: 
Without evdev, xf86-input-keyboard is used for keyboard input. This 
driver was responsible for setting the console to raw mode with 
"ioctl(fd, KDSKBMODE, K_RAW);". One easy way to check if raw mode is 
enabled is trying to press Alt+F1 to switch to another TTY. This should 
not work in raw mode (Strg+Alt+F1 is needed).

Setting the mode to K_RAW in the Server as done on Linux seems more 
correct. I don't fully understand this ioctl yet, though. There is some 
discussion here: 
http://unix.stackexchange.com/questions/173712/best-practice-for-hiding-virtual-console-while-rendering-video-to-framebuffer/178807#178807

I'm using this quickly thrown together patch to set the terminal to 
K_RAW mode:
