Summary:
For Xwayland windows we observed that passing pointer focus to another
window does not trigger proper leave events on X. Which results in e.g.
tooltip windows to show after the pointer moved to a completely
different position on a completely different surface.
This is a bug in Xwayland which will be fixed in 1.19 (already fixed in
master). Given that there is a runtime version check. Although it's fixed
in Xwayland master it's worth to carry a workaround.
To circumvent this problem KWin warps the xcb pointer to 0/0 whever an
X window loses pointer focus. That way the X window gets a proper leave
through the X protocol.
This created a problem though: when giving focus back to the X window it
started to warp the pointer for maximized windows as KWin got pointer
motion events through the X11 event filter for positions on the window
decoration. These are passed into the screen edge filter which pushes
the pointer back and warps our Wayland pointer. To solve this problem
KWin no longer performs any actions for pointer motion in the X11 event
filter if not on X11. The event filter needs to be reworked and most of
it should be moved into the Platform API, if possible.
Test Plan:
Reproduced situations where one could see that pointer updates
don't trigger leave. E.g. going from a highlighted window to the decoration.

Summary:
The mouse polling is also used to detect mouse button press/release
events. This is used e.g. by the MouseClickEffect. The XInput2 filter
only selected for Raw Motion events which means mouse button events
are missed in case it's not combined with a motion.
This change makes the input filter also select for raw button press
and release events. To support this the X11EventFilter needed to
be adjusted to support multiple generic event types to filter for.

Summary:
For an X11 window through Xwayland KWin gets a client message with the
Surface id. KWin has two code paths for handling that:
* Wayland Surface is created after the X11 event
* Wayland Surface is created before the X11 event
In the first code path in WaylandServer KWin called Toplevel::setSurface,
the other code path just updated the m_surface without calling into
setSurface. This means the connects for the Surface were not set up,
resulting in the worst case in accessing deleted memory after the Surface
was destroyed.
This change now ensures that setSurface is called from both code paths.
That should fix the potential crash and could also be a fix to the
problem that sometimes X windows seem to not be damaged correctly.

Summary:
Mouse actions like wheel and double click were restricted to the titleBar
area. This made the top most pixel non-interactive as it's not part of the
titleBarArea.
This change makes the complete titlebarPosition interactive. That is it
includes for a "normal" (top) setup also the TopLeft/Top/Right section.
Thus the top most pixel can be double clicked, mouse wheeled, etc.
For the Wayland case the test case is adjusted.

Summary:
The cursor position is the reference KWin uses while moving a window.
If we don't warp the cursor position the window "jumps" to the cursor
position on first movement.
For requests triggered by the client (e.g. widget style) this does not
matter as the cursor is at the correct position. But for tools such as
task bars we should ensure the cursor is at the right pos.

General handling for mouse driven focus and auto raise should and can
be shared between Client and ShellClient. Thus the code is moved to
AbstractClient and invoked from Client::enterNotifyEvent.
This includes the methods:
* decoration()
* decoration() const
* isDecorated() const
In addition new protected methods are added to destroy the Decoration
and to set it.
Usage of m_decoration in Client code is adjusted.
it seems we can "loose" focus reversions when the closing client hold a grab
(eg. the screenlocker or some games) thus we catch the typical pattern
(though we don't want the focus on the root anyway)

Properly handle the mouse press/release events in InputRedirection
while we move windows. If it's the last mouse release event we end
the move resize of the window. For that we reuse the code written
in Client.
Implementation is moved to abstract_client.cpp as so far events.cpp
does not have any code from AbstractClient.
This includes moving the electricMaximizingDelay from Client to
AbstractClient.
Workaround, this *seems* a Qt problem.
The grab fails while the button is down - Qt then also seems
to release the keyboard.
Not sending it to the deco didn't help either - nevertheless it seems
(from the Qt code) as if the button is currently grabbed
(the code is a dumb forward to xcb_grab_pointer)
As a workaround, the patch simply ensures a grab on releasing a button when
the popup is visible.

Otherwise the old value is polluted because of

We need to send a fake HoverMove event on minimized to remove all
hovered states of the decoration.
At the same time we need to ensure that no further hover events are
sent to a minimized client.

The creation of PlasmaWindowInterface is moved from WaylandServer into
AbstractClient. This allows the sub classes to better control when to
create/destroy the Client.
For creation it's bound to becoming visible - that is Windows which are
only created but never shown are not announced at all.
For Client it's destroyed with the normal tear-down of a Client, for
ShellClient it's destroyed on unmapped (which also means a new one
will be created again in case of another mapping of the surface).
As a side effect, this works around the problem that ShellClients do not
yet get destroyed for QtWayland's menus (needs further investigation).
Adds the SurfaceInterface identified by the surface id we get from
Xwayland. This allows in an easier way to map a Toplevel to a
Wayland surface and will also be useful for Wayland clients.
When XWayland associates a Wayland surface with an X window it
sends a WL_SURFACE_ID client message to the window manager.
KWin listens for this client message in Toplevel and provides it
as a member in Toplevel.
This requires KWin to actually start a Wayland server (and XWayland)
to make proper use of the information.
A wrapper class for MotifHints is added to xcbutils. This class manages
the information about the read Motif hints, so that Client doesn't need
to have a copy of the read states.
The class is designed in a way that during Client::manage we get rid of
another roundtrip.
