Avoid using the "no window manager" code in Emacs

* exwm.el (exwm--on-ClientMessage): Handle fullscreen requests
	for frames.
	(exwm-init): Initialize workspaces after unlocking events.

	* exwm-workspace.el (exwm-workspace--init): Create frames as
	invisible, then make them visible only once their OverrideRedirect
	property has been set.

	* exwm-randr.el (exwm-randr--refresh): New frame parameter
	`exwm-geometry'.

	* exwm-layout.el (exwm-layout--set-frame-fullscreen): New
        function.

The Emacs code is buggy, see https://github.com/ch11ng/exwm/issues/39
