There is a place where this code was called on the main thread.
We're using a rather nasty anti-pattern to just call a block inline rather
than synchonously calling it on the main thread if we're already on the main

it apart right now. This will address the immediate issue.

In Weston, clicking the window decoration of an Xwayland client gives us a
wl_pointer.button event immediately followed by a wl_pointer.leave event.
The leave event does not contain any button state information, so the button
remains logically down in the DIX.
Once the pointer button is released, a wl_pointer.enter event is sent with
the current button state (zero). This needs to trigger a ButtonRelease event
but for that we need to ensure that the device is the same as the one we send
ButtonPress events through.

Trying to change the acceleration/threshold on Xwayland cannot work, and
the corresponding handler xwl_pointer_control() is a no-op.
Yet, an X11 client trying to change those on the touch device may
possibly cause a crash because the touch device in Xwayland doesn't set
that.

We are using the relative pointer for motion events, but buttons and
axis events still go through the absolute pointer device.
That means additional DeviceChanged events that could be avoided if the
buttons and axis events were coming from the same device as motion
events.
Route those events to the relative pointer if available so that motion,
buttons and axis events come from the same device (most of the time).

Xwayland supports relative motion events from the Wayland compositor via
the relative-pointer protocol, and converts those to the absolute range
in device units for raw events.
Some X11 clients however wrongly assume relative values in the axis
values even for devices explicitly labeled as absolute. While this is a
bug in the client, such applications would work fine in plain Xorg but
not with Xwayland.
To avoid that issue, use the relative values for raw events without
conversion, so that such application continue to work in Xwayland.
Thanks Peter for figuring out the root cause.

This add a new flag POINTER_RAWONLY for GetPointerEvents() which does
pretty much the opposite of POINTER_NORAW.
Basically, this tells GetPointerEvents() that we only want the
DeviceChanged events and any raw events for this motion but no actual
motion events.
This is preliminary work for Xwayland to be able to use relative motion
events for raw events. Xwayland would use absolute events for raw
events, but some X11 clients (wrongly) assume raw events to be always
relative.
To allow such clients to work with Xwayland, it needs to switch to
relative raw events (if those are available from the Wayland
compositor).
However, Xwayland cannot use relative motion events for actual pointer
location because that would cause a drift over time, the pointer being
actually controlled by the Wayland compositor.
So Xwayland needs to be able to send only relative raw events, hence
this API.
Bump the ABI_XINPUT_VERSION minor version to reflect that API addition.

Delivery of emulated events usually happens only to the owning client.
If there are grabs, only the grabbing client may receive these events.
This logic does not work during the touch event replay in
DeactivatePointerGrab(), as the previous grab is no longer in the
listener queue of the touch, so the next owner gets whole emulated event
sequence. This may trigger implicit grabs. After replay,
DeactivatePointerGrab() will update the global grab without regard to
this new implicit grab, which leads to issues down the line.
This change is effectively the same as 35e5a76cc1 except that the change
is limited to only emulated pointer events. Otherwise, in the case of a
device grab we end up not sending any touch events to clients that
selected XI_TouchOwnership event and should get touch events before they
get ownership of touch sequence.
Fixes#7https://bugs.freedesktop.org/show_bug.cgi?id=96536
If a XI2 client started listening to touches due to a selection and then
creates an active async grab that does not include touch events, then it
currently won't get the touch end event which will produce inconsistent
view of the pending touches.
Note that we only need to consider touch listeners and can ignore
pointer emulation. Under XI2 if a active grab replaces a passive
implicit grab and the active grab does not include the button release
event, the client won't get it either.
When an X11 client issues an active grab on the keyboard, Xwayland
forward this to the Wayland compositor using the Xwayland specific
protocol "xwayland-keyboard-grab" if it can find the corresponding
Xwayland window.
Some X11 clients (typically older games) however try to issue the
keyboard grab on the X11 root window, which has obviously no matching
Xwayland window. In such a case, the grab is simply ignored and the game
will not work as expected.
To workaround that issue, if an X11 client issues a keyboard grab on the
root window, Xwayland will search for a toplevel window belonging to the
same X11 client that it can use as the grab window instead.
This way, the grab can be forwarded to the Wayland compositor that can
either grant or deny the request based on the window and its internal
policies.
The heuristic picks the first realized toplevel window belonging to the
client so that the Wayland compositor will send it the keyboard events,
and the Xserver grab mechanism will then take care of routing the events
to the expected X11 window by itself.

When enabling or disabling an extension which is not known to the
Xserver, it will log an error message and list the extensions it knows
about.
That clutters the logs when the Xserver is Xwayland spawned by the
Wayland compositor who doesn't actually know the list of extensions
enabled at build time in the Xserver.
Considering that disabling a non-existing extension is a no-op anyway,
list all the extensions available only when attempting to enable an
extension which the Xserver doesn't know about.

The definition relies on IOPortBase, which is only ever set in
hw/xfree86/os-support/bsd/arm_video.c
This caused build failures on linux/mips with GCC 10, due to this
change (from https://gcc.gnu.org/gcc-10/changes.html#c):
"GCC now defaults to -fno-common. As a result, global variable accesses
are more efficient on various targets. In C, global variables with
multiple tentative definitions now result in linker errors. With
-fcommon such definitions are silently merged during linking."
As a result anything including compiler.h would get its own definition
of IOPortBase and the linker would error out.

let's make sure it keeps working.

Pointer-emulated touch events should only be delivered to the client
that owns the sequence even if it's a core client that became the
effective owner of the sequency by selecting for pointer press and
movement.
Currently the emulated events are delivered like this already (see
TouchResourceIsOwner() check in DeliverEmulatedMotionEvent()), except in
the case of TouchEnd, in which case the generated motion event is still
delivered to some client that's not necessarily the owner of the touch
sequence.
We already know whether a touch sequence that is about to emulate a
pointer event has an owner, we just need to check that. This further
allows to simplify DeliverEmulatedMotionEvent() as it won't ever be
called for non-owned touch events.
