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.
If a ShellClient supports the ServerSideDecoration interface we can
create a server decoration for it. For that updateDecoration is added
as a pure virtual method in AbstractClient and a more-or-less code copy
from Client is added to ShellClient.
Geometry handling is adjusted to consider the window decoration offsets.
This change enables kactivities integration by default again on both
X11 and Wayland (as kactivities no longer blocks). As we have an
infrastructure to disable kactivities we can also make use of it and
offer a command line switch to disable kactivities. This might be
useful for using KWin outside of Plasma.

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).

We need to destroy the compositor after Xwayland terminated and after
the internal Wayland connection is destroyed. This means when destroying
the Workspace we may no longer destroy the Compositor at the same time.
Also we need to ensure that other tear down functionality doesn't call
into the no longer existing internal client connection.
With this change kwin doesn't crash when exiting with Wayland and/or
X11 windows still open.
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.
Similar to what we have in Client::manage we should not always
invoke the Placement algorithm. E.g. an initially fullscreened window
should not get placed.
This needs to be extended for more checks similar to Client::manage
and might indicate that we also need a ShellClient::manage.

Holds AbstractClients that is both X11 and Wayland clients. Allows
to easily change code which needs to operate on all clients to get
to them without needing special handling for Wayland clients. At the
same time we are still able to get to the windowing system specific
clients through the old clientList() and waylandServer()->clients().
AbstractClient::mainClients is virtual and overriden in Client,
allMainClients has only a common implementation in AbstractClient.
In activation.cpp we still need one case where a temporary ClientList
needs to be constructed. Once transients are fully migrated that should
be removable again.
This is a temporary workaround for bug 349992 which causes freezes
during startup as kwin and kamd dead lock each other on DBus.
To workaround we don't call Activities::create and check in every
usage of Activities::self() whether the pointer is valid.
As a result kwin_wayland now starts pretty fast.

The PlasmaShell interface allows to create a PlasmaShellSurface for a
given Surface. Through this interface the Surface can request:
* a specific position
* a window type
So far only the window types Normal, Panel and Desktop are supported
which is a sufficient subset for getting plasmashell to work.
In future there should be security checks so that only the dedicated
desktop shell can bind these interfaces.
A ShellClient can have window type dock. In that case it's considered to
have a strut. That is currently every panel restricts the area. On the
other hand only internal clients can be docks at the moment. For Plasma's
panels a dedicated interface will be needed.
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.
When a ShellClient is added and it's not internal, it get placed just
like any other Client. This needs to happen after the initial size is
determined.
Please note: this breaks the positioning of popup windows (e.g. menus)
as they are placed like any other Client. This needs proper popup support
which right now does not yet exist and thus is not much difference to
before.
Adds all internal ShellClients into a dedicated list. This ensures that
we don't perform "normal" window management on them.
In addition we add them to the top of the stacking order. This restores
behavior as it is on X11: internal windows are using BypassWindowManagerHint
and thus on top of everything.
Windows that "belong" to the desktop are
kept visible and do no break the state on
activation/mapping

The signal might be emited by Workspace just before a Client gets
destroyed. In that case the argument carried by the queued event is no
longer valid and causes problems. In EffectsHandlerImpl we can queue
it without problems as the EffectWindow also stays valid if the Client
gets destroyed. The referenced Deleted gets destroyed with a deleteLater,
thus will be after the signal is emitted.

Moves the implmentation to AbstractClient. Methods are no longer virtual,
setActive calls a virtual protected method which is implemented in Client
for Client specific activation code.
