The vidmode extension emulation in Xwayland reports the modeline based
on the current mode.
To do so, it searches for the mode using `xwl_output_find_mode(-1, -1)`
which is supposed to return the current mode, whatever that mode is.
With XRandR emulation, in rootless mode, the default value is the mode
at index 0. That assumption, however is not true when running rootful.
That means that the vidmode extension will always return the highest
mode available, which is 5120x2880, with Xwayland running rootful:
$ xwayland-run -geometry 1024x768 -- xvidtune -show
"5120x2880" 1276.50 5120 5560 6128 7136 2880 2883 2888 2982 -hsync +vsync
Luckily, when Xwayland is running rootful, we have the current mode size
conveniently stored in dedicated fields of the xwayland output struct,
so we can use that to search for the right mode being used and report
that through the vidmode extension:
$ xwayland-run -geometry 1024x768 -- xvidtune -show
"1024x768" 63.50 1024 1064 1176 1328 768 771 775 798 -hsync +vsync
That fixes legacy games using the vidmode extension and rendering at the
wrong size when running within Xwayland rootful.

The code here assumed a `leave` event always occurs between two `enter`
events. On Sway (and presumably other compositors) this happens even if
the client has destroyed the `wl_surface`, but the client gets a null
`surface` here. (Which presumably on on the wire is the id of the
destroyed surface.)
This seems like a bad thing to rely on, and is easy to avoid. But if
this is correct to assume, the Wayland protocol should be explicit about
this.

Currently, we would start dequeuing events as soon as a device is
resumed, regardless of its capabilities.
If the capabilities are not available, we would just fallback to the
regular XTEST code path and not use input emulation.
As a result, it is very likely that we shall lose the first events until
the compositor resumes first a device with the requested capabilities.
To avoid that issue, start emulating only once we have the requested
capabilities, if they match the seat capabilities.

Since commit d370f1e58, Xwayland can optionally be started rootful and
fullscreen.
To do so, it will setup a viewport to scale the root window to match the
size of the output.
However, if the rootful Xwayland window receives an xdg-surface configure
event before the output definition is complete, as with e.g. the labwc
Wayland compositor, we might end up trying to setup a viewport with a
destination size of 0x0 which is a protocol violation, and that kills
Xwayland.
To avoid that issue, only setup the viewport if the output size is
meaningful.
Also, please note that once the output definition is complete, i.e. when
the "done" event is eventually received, we shall recompute the size for
fullscreen again, hence achieving the desired fullscreen state.

Since commit 792758fa ("xwayland: Update lost focus on deactivation"),
in rootful mode, if we receive an "activated" state from xdg-shell
indicating that the surface is no longer active, we shall end up calling
xwl_seat_leave_ptr().
But xwl_seat_leave_ptr() does not actually check whether the seat has
pointer capabilities, and if not, get_pointer_device() will return NULL.
As a result, we would crash using a NULL pointer in GetMaster(). This
typically can happen when using Xwayland rootful on headless compositors
such as "cage" which do not advertise any capabilities for the seat.
To avoid the issue, simply check whether get_pointer_device() returns a
valid non-null device and bail out early otherwise.

With explicit buffer synchronization in use, the window buffers use a
file descriptor for event notification to keep the buffer alive for
synchronization purpose.
When running rootful, the root window (which is visible) is destroyed
directly from the resource manager on server reset, and the window
buffer's eventfd will trigger after the window is destroyed, leading to
a use after free and a crash of the xserver.
To avoid the issue, check whether the window being destroyed is the root
window in rootless mode, and make sure to force the disposal of the
window buffers in that case.

Right now, we would dispose the xwl_window and all the data associated

But not all window destruction go through the unrealize code path, for

step, but straight to destroy window.

The function xwl_window_swap_pixmap() can be called from two places,
either from xwl_window_attach_buffer() or from damage_report().
When called from xwl_window_attach_buffer(), the new buffer is attached
and the surface committed.
However, when called from damage_report(), a new buffer might not be
attached before the surface is committed.
That's fine with implicit synchronization, but if we use explicit
synchronization, committing a surface without a new buffer attached but
with a release timeline point set is a protocol error:
| If at surface commit time there is a pending release timeline point
| set but no pending buffer attached, a no_buffer error is raised.
To avoid such an issue, add a new parameter to xwl_window_swap_pixmap()
to hint whether it should set the synchronization points, and have the
synchronization points set only from xwl_window_attach_buffer().

According to a bug reporter this trips up cmake [1], which expects that
the include directory exists, which it does not since xwayland does not
install any header files.
Add the dataonly directive to pkgsconfig.generate() which will remove
the default "." subdir and ensures that includedir is not set inside the

$libdir/pkgconfig, since it otherwise will be installed to
$datadir/pkgconfig, which precludes programs from finding the pkgconfig
