We were not properly setting the new_descendent field
in Crossing structs for GTK_CROSSING_OUT events. This
was causing extraneous ::leave signals to be emitted,
and make model buttons in popover menus flicker when
hovered.

It doesn't work anymore, since popovers now need
support in the parent, and we don't really need
a demo just for popovers. They are used everywhere
already.

Under grabbing circumstances we used to get several crossing events,
some corresponding to the grab itself and some corresponding to
pointer motion.
The backends now do a better job at keeping those simple, which
means we sit listening for events that don't actually arrive. This
triggers pointer focus issues when dragging windows or opening
grabbing popups.
Actually obey those events, they will be the only ones we get now.
Win32 backend doesn't have support for inhibit shortcuts, yet it needs
support the standard set of GdkToplevel properties.
Add support for the "inhibit-list" object property to GdkToplevel on
win32.
Broadway doesn't have support for inhibit shortcuts, yet it needs to
support the standard set of GdkToplevel properties.
Add support for the "inhibit-list" object property to GdkToplevel on
Broadway.
On X11, there is no such equivalent to the inhibit shortcut protocol
found on Wayland.
To implement the inhibit_system_shortcuts API on X11, we emulate the
same behavior using grabs on the keyboard.
To avoid keeping active grabs on the keyboard that would affect other
X11 applications even when the surface isn't focused, the X11
implementation takes care of releasing the grabs as soon as the toplevel
loses focus.
With the current implementation, we use a `wl_seat` as the key for our
internal has table where we store the Wayland shortcuts inhibitors.
There is however no technical reason for this, and we could use a
GdkSeat instead, which will ease the implementation of the GdkToplevel
shortcut inhibition API.
With the removal of grabs from the public API, we need a replacement API
to let applications bypass system keyboard shortcuts.
A typical use case for this API is remote desktop or virtual machine
viewers which need to inhibit the default system keyboard shortcuts so
that the remote session or virtual host gets those instead of the local
environment.
