Split up screen_scan() 

This splits up screen_scan() into screen_scan_randr(), screen_scan_xinerama()
and screen_scan_x11(). These function try to set up screens via RANDR, Xinerama
and the classic core protcol setup.

No code in these functions was actually changed, only some indentation was
changed (and a "return true/false" added to the first two functions).
