Because there are multiple different types of styluses that can be used with
tablets, we have to have some sort of identifier for them attached to the
GdkDeviceTool, especially since knowing the actual tool type for a GdkDeviceTool
is necessary for matching up a GdkDeviceTool with it's appropriate
GdkInputSource in Wayland (eg. matching up a GdkDeviceTool eraser with the
GDK_SOURCE_ERASER GdkInputSource of a wayland tablet).

On the devices and backends that support it, this signal will be emitted
on slave/floating devices whenever the tool they are interacting with
changes. These notifications may also work as a sort of proximity events,
as the tool will be unset when the pen moves too far.
For backends, gdk_device_update_tool() has been included, all that should
be done on their side is just calling this whenever any tool might have
changed.
GdkDeviceTool is an opaque object that can be used to identify a given
tool (eg. pens on tablets) during the app/device lifetime. Tools are only
set on non-master devices, and are owned by these.
The accounting functions are made private, the only public call on
GdkDeviceTool so far is gdk_device_tool_get_serial(), useful to identify
the tool across runs.
The way master devices detach from their other master counterpart is
vulnerable to infinite recursion due to the way we first recurse on
the other device before clearing the pointer, this may happen if
that last reference to the other master device is held by the
device->associated field.

There is no need for a critical warning just because somebody
asked for a property that is not meaningful for the device.
Just document it as not useful for keyboard devices.
Remove checks for NULL before g_free() and g_clear_object().
Merge check for NULL, freeing of pointer and its setting
to NULL by g_clear_pointer().

Add gdk_device_get_last_event_window(), and use to implement the window
tracking we need for synthesizing crossing events for sensitivity changes
and gtk grabs, rather than keeping the information in qdata and updating
it based when GTK+ gets events.

We've long had double precision mouse coordinates on wayland (e.g.
when rotating a window) but with the new scaling we even have it on
X (and, its also in Xinput2), so convert all the internal mouse/device
position getters to use doubles and add new accessors for the
public APIs that take doubles instead of ints.
gdk_device_list_slave_devices only makes sense to call on master
devices, yet its g_return_if_fail check made it reject such devices.
Pointed out by monty.
_gdk_device_get_axis_use() dates back to pre-sealing, when the
xi2 work began, this remaining can be gone with a public
gdk_device_get_axis_use() function already in place.
GDK_NATIVE_WINDOWS was a way to keep some old apps running that did weird
things in gtk2. We should not have to carry this forwards in gtk 3.x.
We do however keep a g_warning() call reminding people of this fact to
ease debugging when they try to port their applications.

Only master devices must modify the associated device to separate
a pointer/keyboard pair, slave devices must only call
_gdk_device_remove_slave().
Fixes bug 639767 - password not accepted in gnome-screensaver dialog,
reported by Frederic Crozat. On VT-switch, the X server removes its
grab on HW devices, the effect on clients is that slave devices
disappear, and these were mistakenly mangling the master device
hierarchy. so gdk_device_get_associated_device() on the client
pointer wouldn't return the paired keyboard anymore.
The final effect is that gtkplug-x11 wasn't setting a keyboard to
its generated events.
