Xwayland has its own XYToWindow() handler to account for the case when
the pointer leaves an X11 surface to enter another Wayland native window
(which of course are unknown to Xwayland).
When that occurs, Xwayland will treat it as if the pointer had entered
the root window so that the X11 clients receive an appropriate leave
event.
When the pointer leaves the X11 surface, Xwayland will call
CheckMotion() to update the sprite coordinates and possibly the cursor.
However, CheckMotion() will call back into the XYToWindow() handler,
which will then pretend the window has entered the root window, and that
may cause the wrong cursor to be applied.
To avoid the issue, change the order we do things, by calling
CheckMotion() first prior to clear up the internal focus window so that
the first call to XYToWindow() will return the correct X11 window so we
get to update the cursor correctly.

The WriteReplyToClient() macro is used for cases where byte swapping
is implemented in a separate callback function (set in a global vector
table). Since Xwl extension doesn't have such a callback, but does the
byte swapping directly in it's request handlers, there's no need to
call the WriteReplyToClient() macro - we can use WriteToClient() instead.

The cleanup function for GBM is called on the various error paths.
Once xwl_glamor_gbm_cleanup() has been called, GBM support is no longer
usable (and the corresponding data structures are freed), so there is
no way we can keep using GLAMOR after that point.
Make sure to explicitly disable GLAMOR support in that case, so we do
not crash later on trying to use GBM.

Consider the following keymap:
```xkb
xkb_keymap {
xkb_keycodes {
<compose> = 135;
};
xkb_symbols {
key <compose> {
[ SetGroup(group = +1) ]
};
};
};
```
When the user presses the compose key, the following happens:
1. The compositor forwards the key to Xwayland.
2. Xwayland executes the SetGroup action and sets the base_group to 1
and the effective group to 1.
3. The compositor updates its own state and sends the effective group,
1, to Xwayland.
4. Xwayland sets the locked group to 1 and the effective group to
1 + 1 = 2.
This is wrong since pressing compose should set the effective group to 1
but to X applications the effective group appears to be 2.
This commit makes it so that Xwayland completely ignores the key
behaviors and actions of the keymap and only updates the modifier and
group components in response to the wayland modifiers events.

Currently, Xwayland creates a pixmap backed by shared memory buffer as
soon as an X11 cursor is realized, which is destroyed when the cursor is
eventually unrealized.
If an X11 client is leaking cursors, Xwayland will be creating new
pixmaps continuously, which will eventually cause an error once the
limit is reached, and get Xwayland killed.
However, we do not need the shared memory buffer to stay around, we
already have the buffer retention mechanism which will take care of
keeping the buffer around until the Wayland compositor is done with it,
so we could just create and destroy the pixmap as needed when setting
the cursor.
That would not fix the leak in the X11 application, yet that would
mitigate the risk of Xwayland being killed by reaching the shared memory
limits, until the client itself reaches the limit of X11 resources.

The symbol controls whether to include dix-config.h, and it's always set,

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.
