885e9acb6e Drop ApplicationWaylandAbstract
We gain nothing with it. XCB setup logic in the Xwayland server has to
be moved to the workspace layer anyway. For example, this move of
responsibilities will be needed to support running more than just one
instance of Xwayland. Architecture-wise, it would be cleaner too.

Unfortunately, it breaks encapsulation of the Application, but this can
be taken care later.

e09ca74295 wayland: Make workspace responsible for creating Screens
The Screens object is created by Workspace on X11. This change makes X11
and Wayland behave more similar. As is, the Screens is a helper for
window management code, don't use it in backends. Note that the X11 backend
already uses the Screens, it needs to be addressed individually.

d789ecc6d1 Use #cmakedefine01 for all KWIN_BUILD_* macros
This ensures that we get a warning if the config header is not included
instead of compiling the code as if it was disabled. Interestingly, some
checks already used #if KWIN_BUILD_*, so those were generating -Wundef
warnings when the feature is disabled. Commit 886173cab assumed that all
those features were already 01, so this unbreaks the build if any of the
features is disabled.

141947d2e8 effects: Link builtin effects with executables
The main motivation behind this change is to prepare kwin for importing
kwayland-server code in libkwin.

As is, builtin effects are linked with libkwin. Some builtin effects
have wayland specific code. If we move wayland stuff in libkwin, there's
going to be a circular dependency between kwin4_effect_builtins and
libkwin targets.

This change intends to break that dependency by linking builtin effects
to kwin executable.

The main issue with that is that EffectLoader would need to discover the
effects indirectly. QStaticPlugin is used for that purpose.

Besides breaking the cyclic dependency, it makes builtin effects use the
same plugin infrastructure in libkwineffects that external effects use.

Metadata in src/effects/effect_builtins.cpp was converted in a list of
python dictionaries, which was fed to a python script that generated
main.cpp and metadata.json files.

68c675d00d Make source code more relocatable
Occasionally, I see complaints about the file organization of kwin,
which is fair enough.

This change makes the source code more relocatable by removing relative
paths from includes.

CMAKE_CURRENT_SOURCE_DIR was added to the interface include directories
of kwin library. This means that as long as you link against kwin target,
the real location of the source code of the library doesn't matter.

With autotests, things are not as convenient as with kwin target. Some
tests use cpp files from kwin core. If we move all source code in a src/
directory, they will need to be adjusted, but mostly only in build
scripts.

the application is still valid to ensure that no crash will occur

5e60e64a5d Bundle QPA plugin directly
On wayland, we know we're always going to load our internal QPA. Instead
of shipping a plugin and loading it dynamically we can use Qt static
plugins.

This should result in slightly faster load times, but also reduce the
number of moving pieces for kwin.

This also prevents anyone outside kwin loading our QPA which wouldn't
have made any sense and just crashed.

222b558b04 virtualkeyboard: rename class to InputMethod
VirtualKeyboard class does not implement the relevant VirtualKeyboard
protocol but rather implements the InputMethod protcol and can in theory
be used by other input method like e.g. ibus.

Make class name consistent with what it does to avoid confusion in
future.

For now only rename of main class is done and dbus service is kept as-is
to provide retro-compatibility, when input method protocol is
implemented fully, we can think of what to do wrt the dbus interface
later when we fully implement zwp_input_method_unstable_v1 protocol.

19ad172584 Survive Xwayland crashes
If the Xwayland process crashes, it will bring down the entire session
together with itself. Obviously, we don't want that. At least, Wayland
clients should survive the crash.

This change refactors relevant X11 parts to handle Xwayland crashes in a
less fatal way.

In order to handle Xwayland crashes better, a pair of start() and stop()
methods had been introduced in the Xwayland class to allow starting and
stopping the Xwayland process at any moment.

If we detect that the Xwayland process has crashed, we will immediately
stop the Xwayland server, which in its turn will deactivate the socket
notifier and destroy all connected X11 clients. Unfortunately, a couple
of subtle changes in X11Client::releaseWindow() and Unmanaged::release()
had to be made to ensure that we are left with a valid state after the
Xwayland server has been stopped.

826b9742e9 wayland: Terminate client connections before Workspace is destroyed
Summary:
When ShellClient tears down, it needs to access RuleBook in order to
discard temporary rules. The problem is that WaylandServer outlives
Workspace and therefore so does ShellClient.

We can't guard against the case when RuleBook::self() is nullptr as it
is vital to discard temporary rules.

This change adjusts termination sequence so all shell clients are
destroyed before Workspace(and thus RuleBook) is gone.

5e9023948e [wayland] Keep application startup flow inside main_wayland
Summary:
In a recent patch the newly added xwayland class ended up being
responsible for continuing the startup, calling back into the main app
to spawn the workspace.

It moves the flow of startup about so it's not very readable or
following class structure.

This patch moves the code back into main_wayland and removes the
duplication between xwayland and non-xwayland modes.

There was also a misnaming of methods.

Previously:
continueStartupWithScreens was called after platform screens are created
continueStartupWithScene was called after the scene was created
continueStartupWithXwayland was called before xwayland is created

This was confusing, so the names have been shuffled around to follow a
consistent pattern of what has been done so far.

Test Plan:
Started kwin_wayland in normal and xwayland mode
Ran unit tests (though some failed due to a local unrelated and as yet unindentified bug)

6e08fb2fa5 [xwl] Generic X selections translation mechanism with Clipboard support
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.

BUG: 394765
BUG: 395313

Test Plan: Manually and clipboard sync autotest.

c2c92fab51 Ensure the Compositor does not start during termination
Summary:
The SceneOpenGLES test was starting to randomly crash on my system. On
investigation I observed that there was a graphics reset ("Attempting to
reset compositing.") which triggered a delayed restart of the
compositor. This even was only processed while waiting for XWayland to
terminate. Which resulted in a crash in KWin::getXServerVersion as the
xcb connection broke.

It makes no sense to setup the compositor again during application
shutdown. Thus the dtors set a flag that they are terminating the
application and Compositor::setup is checking for it.

Test Plan: Test no longer crashes, although it goes through the crashing path

c8ede9a5ff Build platform plugins in correct sub directory of build dir
Summary:
This brings KWin a step closer to be run from build dir without having
to install at all. The integration tests are adjusted so that the
virtual platform is still found which makes the code be closer to what
is used in normal kwin_wayland.

Test Plan: ctest passes, manually verified correct plugin is loaded
