We no longer need a grabbed seat, instead we'll just use the default
seat if this happens, not without first warning and recommending
gdk_seat_grab() for the operation.
https://bugzilla.gnome.org/show_bug.cgi?id=759309
This allows GDK to unset the grab itself. Also, make sure we unset
the "pointer emulating" touch on the device if this is the
pointer emulating sequence.
https://bugzilla.gnome.org/show_bug.cgi?id=759309
GdkWaylandDeviceData conceptually gathers the data that belongs to
a seat, so it's been renamed (although the old typedef stays, plenty
of refactoring is due here...).
The methods in GdkSeatClass have also been implemented, the most
remarkable is ::grab, which ensures the grab is performed on all
the relevant "master" devices.

On some systems, the gtk settings are not used properly for wayland.
Indeed, g_settings_schema_source_get_default is used, and as the docs says it,
"all lookups performed against the default source should probably be done
recursively.".

Showing the drag cancel animation can be done in the X11
drag context implementation now that we hold the drag
window there, and have the start coordinates.
Since we can't control if and when the application destroys
the drag widget, we take a snapshot of the window contents
and display that during the animation. This should be good
enough for all practical purposes.
Add a variant of gdk_drag_begin that takes the start position
in addition to the device. All backend implementation have been
updated to accept (and ignore) the new arguments.
Subsequent commits will make use of the data in some backends.
In Wayland, the hotspot of a DND icon is set using the buffer offset in
wl_buffer.attach. To implement this, add a private API to cause the
next wl_surface.attach to offset the new buffer with a given offset.
Setting a DND icon hotspot sets this offset while also queuing a redraw
of the window to trigger the wl_surface.attach.

In Gdk, a GdkOffscreenWindow parent has to be the root window. This is
problematic on Wayland because the root window doesn't necessary have the
right information with regard to scale factor.
This patch proposes to rely on the embedder, if available, to derive
surfaces as well as getting the scale factor.
https://bugzilla.gnome.org/show_bug.cgi?id=758936
gdk-wayland backend would not re-configure a surface when its size and
scale match the known size and scale.
But there might be a pending xdg_surface_configure() that would revert
this change so we should re-configure even if the currently known
size/scale match, otherwise we may end up with a wrong size after the
xdg_surface_configure() is received.

If we "release" the button first, the drag will be eventually cancelled,
we must first signal GDK_DROP_FINISHED, and then release the button so
the success status prevails.
It doesn't make a lot of sense to have this stored as data offer data,
rather together with the source_targets array, which is what we're
poking here in the end.

Dissociate ownership from our maintenance of wl_data_source objects.
The only place where ownership must be updated together is
data_source.cancelled, for the other places GDK should take care of
setting up the right ownership, even if at a different order than
we'd expect here.
This fixes GTK+ apps on wayland being locally confused about the
current selection ownership. Because gtk_selection_add_targets()
results in a wl_data_source being created, and ownership being
updated right away, early callers of this will change the ownership
even if the widget it's being called on didn't explicitly request
the selection ownership yet.

While searching for the cause of bug 746745 it was discovered that one could
not set WS_EX_TOPMOST extended window style with SetWindowLong(),
but must use SetWindowPos() for that purpose.
This was never a problem most likely because it is highly unlikely for windows
to acquire/lose WS_EX_TOPMOST after they are created, by means other
than SetWindowPos() (which GTK does use to raise/lower windows and
set/remove keep_above), and because trying to set/unset WS_EX_TOPMOST with
SetWindowLong() results in WS_EX_TOPMOST merely not being set/unset (that is,
other styles are still set/unset within the same call and no error is
signalled).

Instead of having our own copy of the pointer gestures XML file, use
the one installed by wayland-protocols.
Since pointer gestures is an unstable protocol, it went through the
unstable protocol naming convention changes, which is reflected in this
commit.

After the grab is finished, we would expect an enter event, and
GDK updating internally the cursor for that window and device.
This means there is no need at all to store it separately in the
backend.
As a side effect, animated cursors are now also possible on grab
icons.

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.

Other backends take care of the cairo surface destruction in
GdkWindow::destroy. We must do the same here, or the cairo_surface
and its corresponding wl_buffer are left dangling.

This prevents normal application windows (and other kinds of windows)
from being moved up in Z-order to be above windows that have the
always-on-top bit set. Doing so would make the previously-normal windows
in question also always-on-top implicitly.
Windows that are already always-on-top will be restacked on top of other
always-on-top windows too.
