1c3d77eda5 xwayland/present: Update surface window again if manual redirect fails
Even if the manual redirect didn't result in the surface window we
wanted, it might be different again without the redirect.

I don't know of any specific scenario hitting this though, it's more of
a theoretical safeguard.

059bb907ce xwayland/glamor: Try manual redirect only if parent window has depth 32
That's the case 8e8bc0a1ef ("xwayland: Try manual redirection for
surface window in glamor_check_flip") was intended for. If the parent
window doesn't have depth 32, the automatic redirection might have been
done by a client, in which case doing the manual redirection may run
into trouble.

1b51b3270a xwayland: Report correct mode size when rootful
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.

b1ea02b291 xwayland: Release keys on keyboard enter event if leave wasn't received
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.

That allows to build Xwayland with GLAMOR enabled (without DRI3) on

a5c8be657f xwayland/ei: Dequeue events when all caps are available
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.

b813a0be0d treewide: replace xnfreallocarray macro call by XNFreallocarray()
The xnfreallocarray was added along (and just as an alias to) XNFreallocarray
back a decade ago. It's just used in a few places and it's only saves us from
passing the first parameter (NULL), so the actual benefit isn't really huge.

No (known) driver is using it, so the macro can be dropped entirely.

47c4e38e50 xwayland: Make sure output is suitable for fullscreen
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.

64a8365213 xwayland: Check for pointer in xwl_seat_leave_ptr()
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.

002d7d3754 xwayland: Force disposal of windows buffers for root on destroy
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.

8e75a308b5 xwayland: Make sure we do not leak xwl_window on destroy
Right now, we would dispose the xwl_window and all the data associated
with it on unrealize.

But not all window destruction go through the unrealize code path, for
example when the root window (running rootful) is destroyed from the
resource manager on server reset, we do not get to the unrealize window
step, but straight to destroy window.

As a result, we are leaking the xwl_window and all the data associated
with it, for example:

To avoid that issue, check whether there is still an xwl_window
associated with the X11 window on destroy, and if that's the case,
dispose the xwl_window.
