Rework the X windows hierarchy model

This commit add workspace and X window containers support to avoid using
Emacs frames as the parents of X windows.  This should make it easier to
set input focus.

* exwm-core.el (exwm--container, exwm--floating-frame-position): New file
local variables.
(exwm--floating-frame-geometry): Removed file local variable.
* exwm-floating.el (exwm-floating--set-floating)
(exwm-floating--unset-floating, exwm-floating--do-moveresize)
(exwm-floating-move): Use container.
(exwm-floating--fit-frame-to-window): No longer adjust stacking order.
(exwm-floating--fit-frame-to-window): The first member is changed to
buffer.
(exwm-floating--start-moveresize): Use container.  Correctly set input
focus.
* exwm-input.el (exwm-input--redirected, exwm-input--on-focus-in): Removed.
(exwm-input--on-buffer-list-update): Remove the restriction on floating
frames which is no longer valid.
(exwm-input--update-focus): Adjust stacking order.
(exwm-input--on-minibuffer-setup): New function for setting focus on the
Emacs frame when entering minibuffer.
(exwm-input--on-KeyPress-line-mode): No longer compensate FocusOut event.
(exwm-input--grab-keyboard, exwm-input--release-keyboard): Local keys are
now grabbed on the X window container.
(exwm-input--init): Add `exwm-input--on-minibuffer-setup' to
`minibuffer-setup-hook'.
* exwm-layout.el (exwm-layout--resize-container): New function to
resize/reposition both the X window and its container.
(exwm-layout--show, exwm-layout--hide): Use container.
(exwm-layout-set-fullscreen): Use container.  No longer save width and
height.
(exwm-layout-unset-fullscreen, exwm-layout--set-frame-fullscreen): Use
container.
(exwm-layout--refresh): Update a frame parameter.  Remove dead code.
* exwm-manage.el (exwm-manage--manage-window): Reparent unmanaged X windows
to the workspace.  Create X window container as the parent of the X window.
(exwm-manage--unmanage-window): Unmap/destroy container when appropriate.
Use the position of container.
(exwm-manage--unmanage-window): Destroy the container.
* exwm-randr.el (exwm-randr--refresh): Resize workspace using container.
* exwm-workspace.el (exwm-workspace-switch): Raise workspace.
Correctly set input focus.
(exwm-workspace--on-focus-in): Removed.
(exwm-workspace-move-window): Reparent to workspace container.
(exwm-workspace--init): Create workspace frames as visible.
Create workspace containers.
Remove exwm-workspace--on-focus-in from focus-in-hook.
Update _NET_VIRTUAL_ROOTS.
* exwm.el (exwm-init): No longer disable hourglass window.
Initialize workspace module before input.

* exwm-core.el (exwm--debug): New macro for setting debug forms.

* exwm-floating.el (exwm-floating--set-floating): No longer do `exwm--lock'
and `exwm--unlock' since `make-frame' is already adviced to take care of
everything.  Correctly set input focus to the newly created floating
X window.

* exwm-core.el (exwm--floating-edges): Removed file local variable.
* exwm-floating.el (exwm-floating--set-floating)
(exwm-floating--unset-floating):
* exwm-layout.el (exwm-layout--show, exwm-layout-enlarge-window):
* exwm-manage.el (exwm-manage--on-ConfigureRequest):
No longer use floating geometry.

* exwm-input.el (exwm-input--update-global-prefix-keys): Grab global keys
on workspaces containers instead of the root window (or input focus would
transfer to the workspace containing the pointer when the grab is active).
* exwm-workspace.el (exwm-workspace-switch): No longer move mouse.
