Add libdecor 0.1.0 to CI.

When running rootful, the Xwayland window is not decorated (as all
Wayland surfaces), which makes it quite inconvenient to move on screen.
libdecor is "a client-side decorations library for Wayland clients"
which can be used precisely for adding decorations to Wayland surfaces.
Add optional support for libdecor in Xwayland to gain decorations when
running rootful and a new command line option "-decorate".

Xwayland tries to be smart and guess the intention of the X11 clients
sometimes, like issuing a pointer lock when a client hides the pointer
when confined.
While this is a good thing when running rootless, this is problematic
when running rootful as the pointer will be automatically locked unless
the "retro" mode is used (which doesn't hide the cursor, unlike the
default).
Make sure we don't trigger the automatic pointer lock when the cursor is
hidden when running rootful.

When updating the overall screen size, Xwayland would first walk the
window tree then update both the xwl_screen and screen size.
As a result, if any ResizeWindow() handler tries to use the xwl_screen
size, it would get the old (wrong) size instead of the new one.
Make sure to update the xwl_screen size first, prior to traverse the
window tree.
This is preparation work for Xwayland fullscreen mode.

When using xrandr emulation, the emulated mode is passed as a pointer to
the XRandR mode from the xwl_output associated with the X11 client.
In preparation for fullscreen mode, we want to be able to reuse that

Simply change the internal API to pass a reference to the emulated mode.

Keep track of the output the surface enters/leaves.
This is fairly basic tracking though, we do not keep a full list of

When running rootless as well as rootful, Xwayland gets its outputs
configuration from the Wayland compositor.
When running rootful, it means that we end up with a large black
surface the size of all monitors combined, that's not very convenient
and there is no way for set the desired size of the Xwayland window.
Add a new command line option "-geometry" to force a specific mode when
running rootful for the user to specify the root window size to use for
Xwayland.
That option has no effect when Xwayland is running rootless.

Xwayland uses an output serial number it increments each time a new
Wayland output is added.
On server regeneration, that static value is not cleared, and therfore
the output numbers keep increasing each time the Xserver restarts.

which gets recreated on server regeneration, so that index is reset to 0

The function xwl_output_remove() is called when removing a monitor, but
the actual status of the RandR output does not change.
So, when RRTellChanged() is called from update_screen_size(), it won't
have the output connection status up to date in the RandR event
RROutputChangeNotifyEvent and X11 applications relying on that event
like Qt will fail to emit their signal QGuiApplication::screenRemoved.
To avoid that issue, make sure to mark the RandR output as disconnected
prior to call xwl_output_remove().

Move the xcb_aux_sync into the shm path, where we do still need it to
synchronize access with the host. In the non-shm path the image is
copied to the host anyway so the sync just adds latency and keeps you
from using all your network bandwidth.
Only the non-shm-putimage path benefits from this, but the benefit is
significant even on the local machine (here a 3.2GHz Core i7-8700, using

When the pointer leaves an X11 window, and enters a Wayland native
window, Xwayland has no idea about Wayland native windows and may
generate the wrong crossing events to another X11 window instead.
To avoid that issue, Xwayland implements its own XYToWindow() handler to
compare the Wayland focused surface with the X11 window found in the
window tree.
Commit 59ad0e6a ("xwayland: Fix use after free of cursors") changed the
logic in sprite_check_lost_focus() to use IsParent() to compare the
windows, which works when the X11 window is reparented by the window
manager, but fails in the case of an override redirect window.
To fix the issue, also check whether last_xwindow is the window itself.

Adds a -force-xrandr-emulation cmdline switch that always exposes extra
modes when viewporter isn't exposed by the Wayland compositor.
Having the additional modes exposed by the X server is important for
games to function and be configured
Compositors, such as Gamescope (the compositor for Steam Deck),
support only a single window that is rendered in the centre of the
screen that is scaled up to fill the screen by the compositor based
on some user scaling settings.
Exposing viewporter, wouldn't make sense here, and could mislead native
Wayland clients, so exposing dummy modesets in X is preferred here.
