Fix fullscreen mode after switching workspace and back
* exwm-layout.el (exwm-layout--show): Always set an X window in
fullscreen mode the size in fullscreen.
(exwm-layout-unset-fullscreen): Leave the fullscreen mode first.

* exwm-layout.el (exwm-layout--fullscreen-p): New function telling
whether the current buffer is in fullscreen mode.
(exwm-layout-set-fullscreen, exwm-layout-unset-fullscreen)
(exwm-layout-toggle-fullscreen):
* exwm-manage.el (exwm-manage--manage-window)
(exwm-manage--on-ConfigureRequest):
* exwm-workspace.el (exwm-workspace-switch, exwm-workspace-swap)
(exwm-workspace-move):
* exwm.el (exwm-reset, exwm--on-ClientMessage): Use it.
