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
