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.

v3: Keep sending raw emulated events with RAWONLY (Peter)

(cherry picked from commit b5e1f13681)
We're keeping it for unit tests, but we don't want to ship it from this
branch.
Also disable Xvfb in CI for ninja test. It's still built and used for
unit tests as part of ninja dist, but we don't want to run XTS on Xvfb.
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.
While this isn't critical yet, it might become so at some point, so
let's make sure it keeps working.
Don't set the PIGLIT/XTEST_DIR variables for ninja dist, testing XTS

1.4.1 (Peter Hutterer)
Since commit b3f3d65e, xwayland now supports the command line option
"-listenfd" for passing file descriptors and marked "-listen" as
deprecated for this specific purpose.
Add a new pkg-config variable "have_listenfd" to the xwayland.pc so that
compositors can know this is available and use listenfd in place of the
deprecated option.

There are currently no callers that make use of the "created" output parameter
of xwl_glamor_pixmap_get_wl_buffer. Remove it, along with the corresponding
argument of the associated EGL backend entrypoint.
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.

All of these uses were attempting to set FD_CLOEXEC, which happens to be

never going to have the low bit set, so we were never actually setting

Glamor requires at least big GL 2.1 or GLES2, therefore Xwayland tries
to initialize first GL and then GLES2 if that fails.
It does that all in one single function which makes the code slightly
complicated, move the initialization of big-GL and GLES2 to separate
functions to help with readability of the code.
