Drop the public filtering API. The x11 backend already has
the ::xevent signal as replacement. The win32 backend needs
a similar signal to replace filtering.
Reshuffle header inclusions in the x11 backend a little bit
to avoid a cyclic inclusion between gdkprivate-x11.h and
gdkdisplay-x11.h that is otherwise causing problems.
Remove all the old 2.x and 3.x version annotations.
GTK+ 4 is a new start, and from the perspective of a
GTK+ 4 developer all these APIs have been around since
the beginning.
As far as possible, use per-display debug flags.
This will minimize the debug spew that we get from
the inspector if it is running on a separate display.
The g_print documentation explicitly says not to do this, since
g_print is meant to be redirected by applications. Instead use
g_message for logging that can be triggered via GTK_DEBUG.
Since XIQueryVersion, the bad API that it is, enforces the version from
the first client that requests it, for clients to be able to use the new
features in XI2.3, we need to ensure that we pass XIQueryVersion 2.3 as
the version that we support. We know that GTK+ won't be confused by the
new features.

The X server should fill in the minor version that it supports in the
case where it only supports the older version, so we can safely always
pass a higher version number than is potentially supported by the
server.
libXi was designed to be stable in the case where it doesn't recognize
requests or events/replies, so this should still work in a case where
we have new versions of the X server, and GTK+, but an old version of
libXi, at least for however well that setup should work.

Translate XI_TouchBegin/Update/End to GDK_TOUCH_BEGIN/UPDATE/END
events.
At the same time,
set pointer-emulated flags on button events with XIPointerEmulated
and on touch events emulating the pointer.
This function can be used to find the GdkDevice wrapping
an XInput2 device ID. For core devices, the Virtual Core
Pointer/Keyboard IDs (2/3) may be used.
This function can be used to find out the XInput2 device ID
behind a GdkDevice, mostly useful when you need to interact
with say Clutter, or raw libXi calls.
Moving the direct-access redefinitions of various macros
to gdkprivate-x11.h and use that header throughout in x11/.
Also remove a workaround for a long-fixed X server bug.
The X11 backend exports a number of symbols which are _-prefixed
(so don't become part of the gdk api), but are not named in a
way to prevent accidental clashes between backends.
The one API change here is that the gdk_xid_table functions
have been removed - they did not server an purpose, since the
xid table only stores windows anyway, and we already have a
lookup-by-xid function for windows.
gdk_enable_multidevice() has been replaced with gdk_disable_multidevice(),
so applications may call that function if they want to go back at the
previous behavior.
There would be usually little reasons to call that function, unless the
application is doing X calls itself that count on old fashioned core
devices.
* _gdk_device_set_associated_device() did not allow NULL device
* GdkDisplay should dispose device manager to avoid devices
trying to touch the display in finalize
* GdkDeviceManagerXI did not ref devices in id hash
* GdkDisplayX11 did not ref devices in ->input_devices
