Summary:
Most of the functionality which is special to internal clients is moved
from ShellClient to InternalClient. As KWin's qpa is still bound to the
Wayland protocol InternalClient inherits from ShellClient. Due to that
some aspects in ShellClient are "weird". ShellClient still detects
whether it's an internal client and uses the variable m_internal to
capture the state. This is required as we cannot use the isInternal
method. Most of m_internal usage is in init which is called from
constructor of ShellClient. Thus it's not possible to call into virtual
methods of InternalClient.
Also some of the code is duplicated and some methods are temporarily
marked as virtual.
The next step will be to remove ShmBuffer for internal windows which
should decouple the two implementations further with the long term goal
of having InternalClient inherit AbstractClient directly.
Test Plan:
Run nested KWin, triggered outline (OpenGL case) and debug console (shm case).
InternalWindow unit test still passes.

Summary:
Building upon the generic X Selection support this patch establishes another
selection class representing the XDND selection and provides interfaces
to communicate drags originating from Xwayland windows to the Wayland
server KWin and drags originating from Wayland native drags to Xwayland.
For Wayland native drags KWin will claim the XDND selection as owner and
will simply translate all relevant events to the XDND protocol and receive
alike messages by X clients.
When an X client claims the XDND selection KWin is notified via the X protocol
and it decides if it allows the X drag to transcend into the Wayland protocol.
If this is the case the mouse position is tracked and on entering a Wayland
native window a proxy X Window is mapped to the top of the window stack. This
proxy window acts as a drag destination for the drag origin window and again
X messages will be translated into respective Wayland protocol calls. If the
cursor leaves the Wayland window geometry before a drop is registered, the
proxy window is unmapped, what triggers a subsequent drag leave event.
In both directions the necessary core integration is minimal. There is a single
call to be done in the drag and drop event filter through the Xwayland
interface class.
From my tests this patch facilitates drags between any Qt/KDE apps. What needs
extra care are the browsers, which use target formats, that are not directly
compatible with the Wayland protocol's MIME representation. For Chromium an
additional integration step must be done in order to provide it with a net
window stack containing the proxy window.
Test Plan: Manually. Auto tests planned.

Summary:
In this patch an infrastructure is created to represent generic X selections
in a Wayland session and use them for data transfers between Xwayland windows
and Wayland native clients.
The central manager is the DataBridge class, in which Selection objects can be
created. This is hard-coded and such a Selection object persists until the end
of the session, so no arbitrary selections can be created on the fly. For now
the X Clipboard selection is supported, whose corresponding mechanism in the
Wayland protocol is just called Selection.
A Selection object listens for selection owner changes on the X side and for
similar events into the Wayland server interfaces. If a data provider is
available a selection source object is created by the Selection object. In case
data is requested on the other side, a data transfer is initialized by creating
a Transfer object. A Selection keeps track of all transfers and makes sure that
they are destroyed when they are finished or in case they idle because of
misbehaving clients.
The Clipboard class translates the X Clipboard via a proxy window. Selection
changes on the Wayland side are listened to through a new signal on the active
KWayland seat interface.
The previously used X clipboard syncer helper is disabled. The clipboard sync
autotest is changed to the new mechanism.

Summary:
With GTK applications our code showed issues. With GTK the sequence for
a menu or dialog window is:
1. create surface
2. create server side decoration
3. request csd
4. create xdg_shell_surface
Which result in KWin to have the ServerSideDecoration object being
created before the ShellClient is created. The connect for mode changed
happens in ShellClient, which is too late to catch that the window
requested client side decoration. Thus KWin created a decoration about
things such as a menu.
This change moves the acknowledge of the mode to WaylandServer. As we
anyway always acknowledge the requested mode we can also do it there and
don't require ShellClient to be present. Thus when the ShellClient is
created the mode is properly reflected and no decoration is created.

Summary:
There are two types of constraints supported:
1. Pointer confinement
2. Pointer locking
In the case of confinement the pointer is confined to a given region of
the surface. This is comparable to general operation where the pointer
is confined to the screen region.
In the second case the pointer gets locked. That means it cannot move at
all. No further position updates are provided, only relative motion
events can go to the application. There is a hint about cursor position
update on unlock which is not yet implemented in KWayland::Server, thus
also not in this change.
The implementation in KWin grants the requests for pointer constraints
when the pointer enters the constrained region, either by pointer
movement or by e.g. stacking order changes. There is no confirmation
from user required to enter that mode. But we want to show an OSD when
the pointer gets constrained, this is not yet implemented, though.
Breaking an active constraint is relatively easy. E.g. changing the
stacking order will break the constraint if another surface is under the
cursor. Also (in case of confinement) moving the pointer to an
overlapping window breaks the confinement. But as soon as one moves the
pointer back to the window a constraint might get honoured again.
To properly break there is a dedicated event filter. It listens for a
long press of the Escape key. If hold for 3sec the pointer constraint is
broken and not activated again till the pointer got moved out of the
window. Afterward when moving in the pointer might activate again.
The escape filter ensures that the key press is forwarded to the
application if it's a short press or if another key gets pressed during
the three seconds. If the three seconds way fires, the later escape
release is not sent to the application.
This basic interaction is also ensured through an added auto test.
This change implements T4605.

ignorant about the windowing system a PlasmaWindow uses.

is just like findClient(Surface*) with the difference that it returns
an AbstractClient instead of a ShellClient*.

If we try to query before WaylandServer created the KSldApp the service
owner change is never delivered. Thus a delay till we know that the
service is there on Wayland. On X11 the initialization can be done
directly.
To know when the WaylandServer is fully initialized an additional
signal is added to WaylandServer.
Summary:
Most platforms like the nested and virtual do not handle the outputs
themselves and WaylandServer announces the Outputs to Wayland.
So far this was static: at startup it got announced once to Wayland
and any changes were not catched.
This change makes WaylandServer listen to changes to the Screens and
sync them to Wayland.
Unfortunately KWin's internal Screen information is not sufficient to
properly synchronize this to Wayland and also Wayland by not supporting
adding/removing modes does not help.
Thus the solution implemented here is to add new outputs reflecting the
changes and then removing the old ones. This creates situations with more
outputs being present than actually there, but prevents that there are
no outputs at all.

Summary:
The clipboard sync is done by a dedicated helper binary launched by
KWin. This helper binary is forced to xcb platform to piggy-back on
Qt's implementation of the X11 clipboard. In addition it implements
the Wayland clipboard - which is much simpler. Reading the Wayland
clipboard is based on the implementation in QtWayland.
KWin internally knows the DataDeviceInterface belonging to the helper
application. Whenever an xwayland client is focussed, this DataDevice
is allowed to set the selection and KWin manually updates the current
selection in the SeatInterface. By that the sync from X11 to Wayland
is implemented. When afterwards a Wayland client is selected, it's sent
the current selection which references the X clipboard and a data
transfer can be initiated in the normal Wayland way.
For the other direction KWin sends the current selection to the helper's
DataDevice whenever an xwayland window is focused. The helper application
reads the Wayland clipboard and sets it on the X11 clipboard. Thus the
Wayland clipboard is synced to X11.
The approach used here will also be useful for implementing a clipboard
manager (aka klipper).
Currently the implementation is not yet fully completed. We need to
make sure that the helper application gets restarted in case of a crash.
