Summary:
The idea behind the debugging console is to have a feature comparable
to xprop and xwininfo just for Wayland. We cannot have command line
utils as that violates the security restrictions, thus it needs to be
exposed directly in KWin.
The debugging console is invoked through DBus:
qdbus org.kde.KWin /KWin showDebugConsole
This opens a window with a tree view. The DebugConsoleModel which is
used by the tree view groups all windows into four categories:
* x11 clients (that is Workspace::clientList() and Workspace::desktopList())
* x11 unmanaged (Workspace::unmanagedList())
* wayland shell clients (WaylandServer::clients())
* wayland internal clients (KWin's own QWindows - WaylandServer::internalClients())
Each window is a child to one of the four categories. Each window itself
has all it's QProperties exposed as children.
This allows to properly inspect KWin's internal knowledge for windows and
should make it easier to investigate problems. E.g. what's a window's
geometry, what's it's window type and so on.
The debugging console is intended as a developer tool and not expected to
be used by users. That's why it's invokation is rather hidden. Due to
the fact that it's internal to KWin it results in:
* no window decoration
* stealing keyboard focus
* no way to resize, close, move from KWin side
* rendered above all other windows
There is a dedicated close button to get rid of it again. While the
console is shown it's hardly possible to interact with the system in
a normal way anymore. This is something which might be improved in
future.
At the moment the model is able to update when windows are added/removed,
but not yet when a property changes. Due to the lack of interaction with
the existing system, that's not a high priority at the moment, but can
be added in future.

Similar to the change regarding pointer and touch a
KeyboardInputRedirection is created. The Xkb class is also moved to
the new files keyboard_input.h and keyboard_input.cpp.
Just like in the case of PointerInputRedirection no signals are added,
but the existing signals in InputRedirection are directly invoked.
All pointer related code is moved into a new class called
PointerInputRedirection.
The main idea is to simplify the code and make it easier to maintain.
Therefore also a few changes in the setup were performed:
* before init() is called, no processing is performed
* init() is only called on Wayland and after Workspace is created
* init property is set to false once Workspace or WaylandServer is
destroyed
Thus code can operate on the following assumptions:
* Workspace is valid
* WaylandServer is valid
* ScreenLocker integration is used
The various checks whether there is a waylandServer() and whether
there is a seat are no longer needed.
Some of the checks have been reordered to be faster in the most common
use case of using libinput. E.g. whether warping is supported is first
evaluated by the variable bound to whether we have libinput and only if
that is false the backend is checked.
The new class doesn't have signals but invokes the signals provided
by InputRedirection. I didn't want to add new signals as I consider
them as not needed. The areas in KWin needing those signals should
be ported to InputEventFilters.
Replaces the timer based polling approach. If XInput is available we
listen for the RawMotion event on the root window and use this to
trigger a mouse pointer position.

In order to increase the security we disable ptrace on kwin_wayland.
This makes it impossible for a another process running as the same
user to attach to kwin_wayland to install a key logger. It doesn't
protect against higher privileged users, but that's no problem: they
can just read the input device file and don't need to attach to KWin
to become a key logger.
This change is highly inspired by a similar change to kscreenlocker.
A difference is that KWin checks whether we are running under a
debugger. In such a case we still want to allow ptrace.
This is needed to make KWin build-able on non-Linux, but is actually
only a workaround. The dependency should also be available on non-Linux.
This disables the EGL integration in the Wayland backend (QPainter still
available) and the EGL fallback in the qpa plugin (preferred context
sharing still available, but requires a working OpenGL Scene).

The implementation of VirtualTerminal is too linux specific and doesn't
compile on e.g. freebsd. Currently the most usage is in combination with
libinput. Only usage is:
* libinput related functionality in InputRedirection
* backends without custom input handling
Thus binding the feature to whether libinput is available is currently
the least invasive approach to get it compile on non-Linux.
In the long run this needs a different solution. The functionality
provided by VirtualTerminal is required and without the backends don't
work. It's needed to get notified about VT switches, when KWin needs to
stop rendering. So a solution for non-Linux needs to be found if
non-Linux wants to provide Wayland in future.

Basically a simplified fork from kwayland-integration.
We cannot use the idletime plugin from kwayland-integration as it
a) doesn't react on our own qpa plugin name
b) performs blocking roundtrips in the main thread -> freeze
This simplifies by using our internal registry and we don't even check
whether Seat and Idle are announced: we know they are.

This introduces --lockscreen option in kwin_wayland which when used will
lock screen immediately. Also dependency to newly created kscreenlocker
repo is introduced.

So far it was bound to whether we build for GLES. But this is
semantically wrong. It might be possible that even on desktop gl
epoxy is built without GLX support, thus we need to reflect this.
This change ensures that epoxy/glx.h is only included if available,
that relevant code is bound to it and that checks are in place to
enforce EGL if not build with glx support.
In addtion the glxbackend.cpp is now only included in the build set
if available.
...and use PATH_VARS to make the config file work with absolute paths.
Two reasons to do this:
- DBUS_INTERFACES_INSTALL_DIR is marked deprecated
- Not hard-coding the packackage prefix is helpful on a multiarch
layout where the prefix is /usr/${host} but arch-independent files
should still be installed to /usr/share (i.e a level below the
prefix).

We no longer need to have the event dispatcher created before starting
the QApplication, thus we can leave it to the QPA plugin to creat it.
Also we don't need to implement our own dispatcher any more but can
use one from Qt5PlatformSupport as we link it anyways. The special
need for dispatching the WaylandServer is no longer needed as we can
explicitly dispatch it from the QPA plugin if needed.
This introduces an own QPA plugin for KWin. QtWayland's plugin is not
a good solution for KWin as QtWayland is meant for Wayland clients and
not for a Wayland server. Given that it makes more sense to have a very
minimal QPA plugin which supports the use cases we actually have.
With our own QPA plugin we should be able to improve the following
areas:
* no need to create Wayland server before QApplication
* Qt::BypassWindowManagerHint can be supported
* no workaround for creating OpenGL context in main thread
* sharing OpenGL context with Qt
* OpenGL context for Qt on libhybris backend
The plugin supports so far the following features:
* creating a QPlatformWindow using KWayland::Client (ShellSurface)
* creating a QPlatformBackingStore using a ShmPool
* creating a QPlatformOpenGLContext with Wayland::EGL
* or creating a QPlatformOpenGLContext which shares with KWin's scene
* creating a QPlatformScreen for each KWayland::Client::Output
* QPlatformNativeInterface compatible to QtWayland
Let's rather not build the plugin if we don't have the dependency
then building it without OpenGL support. Simplifies the code a bit
and makes the backend overall more useful and goes along with e.g.
the Wayland one which has EGL also as a hard dependency for the
plugin.

The build option wasn't used for 5.x at all and in this way doesn't make
any sense nowadays. We want to have a converged desktop which also means
that the window manager should be able to switch to a different form
factor with a full feature set (plug in external screen to smartphone and
it should be full desktop). A trimmed down KWin with compiled out
functionality cannot do that. Also the need for trimmed down KWin becomes
less and less important given the improved hardware we target nowadays.
This change got triggered by the announcement to close down the Plasma
Active mailinglist [1], which shows that having a build option called
Plasma Active is no longer needed.

It doesn't make much sense any more as we do no longer link EGL since the
switch to epoxy. And epoxy pulls it in at runtime if needed.
Even more on Wayland it's just plain stupid to have EGL disabled. So
removing the option just simplifies our code base without any
disadvantages.

The problem with KToolInvocation is that it creates a dead lock on
Wayland in case kdeinit is not already running. It starts kdeinit
and does a QProcess::waitForFinished and our kdeinit needs to interact
with the wayland server. So dead lock.
As KRun also calls into the dangerous code path it's no option which
leaves us with QProcess to start the processes.
A nice side-effect is that we no don't need to link KF5::Service any
more from kwin_core. Now once Plasma and Notification don't use it
any more, it will be gone completely.
kdeinit_executable doesn't make sense in the case of kwin_wayland as
start_kdeinit_wrapper will be executed after kwin_wayland thus the
framework doesn't work.
The KGlobalAccelD which gets created by KWin needs a plugin for the
platform specific parts. This change introduces such a plugin. It's
linked against kwin so that it can integrate with the core.
On enable the plugin registers itself in the InputRedirection and
GlobalShortcutsManager checks the plugin whether a shortcut got
triggered.
As the loading of the plugin must happen after InputRedirection is
fully created a dedicated init method is added to InputRedirection.

We need XCB 1.10 for sync to work. Sync was optional with a version check
to make it work on build.kde.org. The CI system supports XCB 1.10 now, so
it's better to have it as a mandatory requirement.
KWin used the wrong event dispatcher: QEventDispatcherUNIX insted of
QUnixEventDispatcherQPA. This caused QWindow related events never to
be send to their destination. Which is one of the reasons why KWin's
own windows are not shown at all.
As we cannot easily use QUnixEventDispatcherQPA we do the same as
that class. Inherit from QEventDispatcherUNIX and call into
QWindowSystemInterface::sendWindowSystemEvents.
