Use X window borders

Browse source 
; This commit replaces the internal borders of Emacs frames with X
; window borders.  This should make the flickering issue of floating X
; windows less serious.

* exwm-floating.el (exwm-floating--border-pixel)
(exwm-floating--border-colormap): New variables for storing border pixel
and its colormap.
(exwm-floating--set-floating): Do not set the internal border (and
background color) of floating frames; do not take
`exwm-floating-border-width' into account when calculating geometries;
set the border of floating X window containers.
(exwm-floating--unset-floating): No need to restore the position of X
windows any more; hide the border of floating X window containers.
(exwm-floating--init): Initialize the border pixel.
* exwm-layout.el (exwm-layout-set-fullscreen)
(exwm-layout-unset-fullscreen): Show/Hide container border respectively.
* exwm-manage.el (exwm-manage--manage-window): Set the border pixel and
colormap of X window containers.
* exwm-workspace.el (exwm-workspace-move-window): Do not set the
internal border and background color of floating frames.
* exwm.el (exwm--on-ClientMessage): Simplify the code for calculating
_NET_REQUEST_FRAME_EXTENTS.
