Summary:
This implements a wrapper class for the wl_eglstream_controller Wayland
interface. It allows clients to inform the compositor when a new EGL Stream has
been created with an Wayland surface attached as its producer. The compositor
can then bind a GL texture as the stream's consumer allowing it access to the
surface's buffer contents for presentation. The only client currently expected
to make use of this interface is the NVIDIA EGL driver when running alongside a
compositor supporting EGLStream-based buffer sharing.

Summary:
When we add WMBase (the new name stable XdgShell) we get a clash with
XDGShellV5. This clash consists of all functions in the generated C file
which clashes at linker time, as well as multiple xdg_blah_interface
structs which would get redefined.
XDGShellV5 in practice is used by literally no-one (Qt never defaulted
to it if wl-shell was available) and has been dropped from GTK when
they added v6. But it's used by some kwin unit tests so breaking
would cause issues for stable kwin release tests... so it's a pain.
We can't mod the XML as we need the strings sent down the wire to remain
the same and we need the same names for our forward declared structs
that the client code can cast to.
This patch copies the generated files and modifies them manually.
Hacky, but we know this code will never change again - and IMHO this
task isn't one worth investing too much time into.

Done primarily for XWayland which for legacy reasons doesn't assume the
logical size of a display is pixelSize / outputScale. Meaning xwayland
windows that position themselves are wrong in a scaled environment.
It also allows the possibility for us to support fractional scaling
whilst keeping wl_output::scale as an integer.
The protocol is a bit odd as it operates via the FooManager + Foo
pattern rather than using globals like Output so I've wrapped it so it
behaves more like globals.

Summary:
This protocol allows to indicate that a wl_surface should inhibit idle
actions such as DPMS, screen locking if the surface is visible.
The protocol is quite simple: it just creates an IdleInhibitor for a
Surface. If such an IdleInhibitor exists the Surface is considered to
inhibit idle.
On the server side it is also exposed like that through the API. The
IdleInhibitorInterface is private to the library and only
SurfaceInterface is extended to expose whether it currently inhibits
idle.

Summary:
Implement the "foreign" wayland protocol.
A client can export a surface with an unique string as handle,
then another client can refer to that surface and set an own surface as
child of that surface.
Potential use cases are out-of-process dialogs, such as file dialogs,
meant to be used by sandboxed processes that may not have the access
it needs to implement such dialogs.
The handle needs to be shared between the processes with other means,
such as dbus or command line paramenters.
The public api of the server side only tracks parent/child relationships as this is the only data kwin would need it for, the rest of the api is not exported so should be safer from eventual protocol changes
Test Plan:
the autotest works, but has a lot of random crashes when deleting surfaces,
unfortunately backtraces don't tell much and the crashes never occur when running into valgrind
behavior may still be wrong, depending on how the protocol is supposed
to work if more clients try to set the same exported surface as parent

Summary:
The main clever part that's not just boring boiler plate is how we
handle the structure change
A surface now has an XDGSurface which then has a an Xdg TopLevel or a
Xdg Popup
We need to fit this into the public API which assumes a surface has a
Surface or a Popup.
The old Surface is similar to the new TopLevel.
The shoehorning works by relying on the fact that a surface without a
role is pretty useless.
Clients create the surface implicitly with the toplevel or implicitly
with the popup.
The server only announced it has a new "XdgSurface" when it gets a new
zxdg_surface_get_toplevel.
----
Popup decisions:
- On popup creation the server should copy the current info from the
positioner and then it gets deleted. Given kwaylands job is to keep
state, we expose all these parameter via popup.
- Due to this positioner is not exposed as a resource anywhere.
- Server API is 100% backwards compatiable.
i.e new code will work identically with v5 clients.
- Client API is not. Grabs are called separately from the constructor,
and the parent surface changed to an xdgsurface, not a raw surface.
V5 code still works as-is, just not with the new constructors.
It seemed better to match the v6 (and what will be the stable v7) than
to try and do hacks and lose functionality.
Given the client needs to change the code to opt into V6 anyway. I don't
think this is a huge problem.
Test Plan: Current test still passes.

Summary:
The pointer constraints protocol is an unstable protocol and thus
the implementation follows the semantics of unstable protocols.
The protocol allows to create a constraint on the pointer - either a
lock or a confinement on a surface. Those are not activated at once, but
when the compositor actively grants it.
During lock no further pointer motion is emitted, during confinement the
pointer is kept in a certain area.
This implements T4451.

Summary:
Pointer gestures are created for a pointer and there are two types of
gestures: swipe and pinch.
At a given time there can only be one active gesture. The implementation
in SeatInterface ensures that there can only be one active gesture.
Each gesture consists of a start event, 0 to multiple update events and
an end event. The end can also be a cancel. To better support this the
implementation doesn't follow the protocol and splits end and cancel
into dedicated methods in the server side and into dedicated signals in
the client side.

This is ancient code that is outright wrong most of the time and at best
just incredibly unnecessary.
It is also not present in the great majority of frameworks due to this.
Its wrongness comes from the fact that it hardcodes the installation path,
which breaks relocatability of the KF5 tree as it will always attempt to
find the include dir $PREFIX/KF5 (e.g. /usr/include/KF5), which may or may
not exist given that the tree was relocated.
Worse yet, in a cross-building scenario we maybe for example
build on ARM and install to /usr but for cross building take the entire ARM
tree and shift it into /arm/usr/. If we then crossbuild on that tree the
bogus include list in this framework will make sure that we always search
in /usr/include/KF5 and thus potentially load a !ARM header simply because
the relevant ARM header was not installed etc.. Similarly of course a
build in $HOME can pick up /usr/include/KF5 headers because the home ones
are missing, causing unexpected results.
This happens whenever the KDE_INSTALL_INCLUDEDIR_KF5 var is absolute, which
it usually is.
On top of all that the premise of the code in question is flawed. It seeks
to add $PREFIX/$KF5INCLUDES to the search paths (e.g. /usr/include/KF5).
This is unnecessary because the target itself is properly installed via
cmake's install(TARGETS ... EXPORT ...) function [1]. This function has
smart functionality built in which will add the passed INCLUDES destination
to the INTERFACE_INCLUDE_DIRECTORIES property of the targets (i.e. what
the useless code wants to do) [2].
So what happens is that we install the target to the
KF5 locations, which has "include/KF5" as INCLUDES location,
thus causing the correct path to be added to the includes list of the
Targets.cmake file.
In particular thanks to more internal magic in cmake it will do so with
automatically resolved root paths such that the installed tree is
relocatable and able to relatively find the other KF5/* headers. So it
does what the code in question wants to do, just correctly.
Since cmake automatically takes care of injecting $prefix/include/KF5 we
can simply get rid of the wrong custom inejection code. This makes the
generated cmake file find the correct include/KF5/ directory and stops it
from always expecting a /usr/include/KF5/ directory to be present.

CHANGELOG: Improved relocatability of CMake export
Summary:
Especially for Xwayland windows the compositor might not have a themed
icon name. Resulting in a task manager not having dedicated icons for
Xwayland windows.
This change deprecates the way how a compositor is supposed to set the
window icon. Instead of passing the themed icon name, it is now supposed to
pass the QIcon. In case it's a themed icon the existing way to pass to
the client is used.
Otherwise a new event is used to inform the client that there is an icon
- no data is transmitted at this point. The client can then create a
file descriptor and pass it to the compositor. The compositor serializes
the icon into the file descriptor and the client can read from it. This
all happens transparently on client side there is no api change at all.
The writing and reading of the icon is done in a thread. Due to that
Qt5::Concurrent is now a required dependency instead of an optional
dependency.

Summary:
This change implements the zwp_relative_pointer_v1 protocol which allows
to send relative motion events.
The (unstable) protocol consists of a RelativePointerManager which
creates RelativePointers for a given Pointer. This interface currently
only has one event to report the relative motion. It carries the delta,
the non-accelerated-delta and a timestamp in microsends granularity.
On the server side the implementation is mostly internal. Once a
RelativePointerManagerInterface is created one can send relative motion
events through the SeatInterface. The SeatInterface takes care of
sending it to the responding RelativePointerInterface. The protocol does
not restrict the sending of "normal" and relative motion events. Thus it
can be combined in any way one wants. This allows to have a rather
simple implementation. A user of the SeatInterface can just start to
feed the relative motion events (if the information is available) to the
SeatInterface together with the pointer events.
On client side a new RelativePointerManager and RelativePointer class
are added. The RelativePointerManager creates the RelativePointer for a
given Pointer. The event sent to RelativePointer is transformed in a
normal signal.

Summary:
This change introduces support for the unstable xdg-shell interface in
the server. The implementation is based on version 5 of the unstable
interface. This is the version used by toolkits like e.g. GTK.
There is also a version 6 of the protocol under development which is
incompatible. This makes it difficult to implement it in a backward
compatible way.
Because of that the implementation is a little bit different to other
interfaces and inspired by the TextInput interfaces:
On client side an XdgShell class is exposed which does not represent
it directly. Instead it delegates everything to an XdgShellUnstableV5
implementation. For the Surface/Popup the same is done.
In the Registry it's possible to create an XdgShell and it accepts
the XdgShellUnstableV5 and in future will accept XdgUnstableV6, etc.
On server side it also follows the approach from TextInput. That is
there is a version enum which gets passed to the factory method in
Display. It currently supports only V5, but in future can be extended
for V6. As there is lots of similar code between wl_shell, xdg_shell
and in future xdg_shell_unstable_v6 a templated GenericShellInterface
class is added which combines the common parts.

Summary:
This change introduces support for text input. Text input allows to
compose text on the server (e.g. through a virtual keyboard) and sent
the composed text to the client.
There are multiple interfaces for text input. QtWayland 5.6 uses
wl_text_input, QtWayland 5.7 uses zwp_text_input_v2.
wl_text_input is from pre Wayland-Protocols times and considered as
UnstableV0 in this implementation. The other interface is UnstableV2.
Unfortunately the V2 variant is not yet part of Wayland-Protocols, but
used in Qt.
The implementation hides the different interfaces as good as possible.
The general idea is the same, the differences are rather minor.
This means changes to how interfaces are wrapped normally. On client
side in the Registry a manager is factored which represent either of
the two interfaces. Similar on the server side Display's factory method
takes an argument to decide which interface should be factored. This
way a user of the library can expose both interfaces and thus be
compatible with Qt 5.6 and Qt 5.7 onwards.

This implements the server part of the screen management protocol. The
protocol is implemented as a wayland protocol.
It provides the following mechanisms:
- a list of outputs, close to wl_output, with additional properties for
enabled, uuid, edid, etc.. These OutputDevices correspond to a
connected output that can be enabled by the compositor, but is not
necessarily currently used for rendering.
- a global OutputManagement, which allows creating config objects, one
per client. The client can make changes to the outputs through
setScale(outputdevice*, scale) for example.
- an OutputConfiguration resource, that can be handed to a client and
used for configuration. Changes are double buffered here. Only after
OutputConfiguration.apply() has been called, the changes are relayed
over the global OutputManagement.
The compositor is responsible to handle changes.
For a more detailed description, see the API docs in especially
outputconfiguration.h.

In addition there is an offset on each side.

This interface allows a client to fake input events and the server
might use them. There is an authentication mechanismn in place which
requires the server to mark the client as authenticated in order for
any events to be emitted at all.
This interface is intended for use cases like kdeconnect which allows
to remote control a device.
The idle time interface is modelled for the use cases of the KIdleTime
framework to allow providing a Wayland specific implementation.
It supports registering idle timeouts which are triggered on server
side if there has not been any user activity on the seat for the
requested amount of time. Once user activity resumes a resume from idle
signal is emitted.
In additon there is the possibility to simulate user activity which
simulates the resume from idle.
The Qt surface extension is a small protocol to allow exchanging
additional data between QWindows and the compositor. What we are
currently only interested in is the possibility to close a surface
from the Compositor.
Protocol description is copied from QtWayland 5.4.2 branch.
Uses eglQueryWaylandBufferWL (if available) to determine the size of the
buffer. In order to do so, the server library links against egl (1) and
one needs to register the EGLDisplay in Server::Display by the user of
the library. For this a new method Display::setEglDisplay is added.
