Xephyr: add "multiscreen" suport
* This patch adds multiscreen support to Xephyr. For instance, the command line : "Xephyr :4 -ac -screen 320x240 -screen 640x480" will launch with two "screens" - namely two main windows. The first main window represents a screen that has the number :4.0, with a geometry of 320x240 pixels, and the second one represents a screen that has the number :4.1 with a geometry of 640x480. The command line: "DISPLAY=:4.1 xclock" will launch the xclock program on the second screen, for intance. * this patch was edited by Dodji Seketeli <dodji@openedhand.com> for: - better style compliance with the rest of the Xephyr code - make sure Xephyr could be launched with no -screen option. By default that creates a default screen of 640x480 pixel like before - display full titles on the windows - with insctructions to grab keyboard and mouse - like before.
