f12cf0efba Replacement class for QCursor
With Qt5 QCursor does no longer provide ::handle() which was used to
set a cursor on a native XWindow for which we do not have a QWidget.

Also KWin has had for quite some time an optimized version to get the
cursor position without doing XQueryPointer each time ::pos() is called.

These two features are merged into a new class Cursor providing more or
less the same API as QCursor.

In addition the new class provides a facility to perform mouse polling
replacing the implementations in Compositor and ScreenEdges.

For more information about the new class see the documentation for the
new class in cursor.h.

986d9e5613 Delay releasing the compositor selection
When turning off the compositor do not release the compositor selection
directly but delay it through a timer. The idea is that the internal
change when e.g. restarting the compositor or switching from XRender to
OpenGL should not be visible to the outside world.

This hopefully makes restarting the compositor more robust in Plasma due
to the SelectionWatcher sometimes reporting incorrect results.

When restarting KWin the change does not matter as the selection gets
force claimed by the new instance anyway.

9820e4daf6 Introduce dedicated suspend and resume methods on Compositing interface
The new methods suspend and resume are meant to provide a better way to
influence the current compositing state than toggleCompositing. In
addition an overload setCompositing(bool) is added. The resume method is
implemented in a way that it can be used to try to start the compositor
again in case it failed.

Internally the method suspendResume is dropped as it does the same as
setCompositing just with inverted binary logic and worse name. The
compositingToggled signal is now emitted from within setup and finish to
ensure that especially the compositingToggled(true) signal is only
emitted if the Compositor could start.

Also the updateCompositingBlocking is adjusted to use the new dedicated
suspend and resume methods instead of the toggle method.

35237aadcb Splitting up of KWin's global D-Bus interface
Two new interfaces are introduced:
* org.kde.kwin.Compositing
* org.kde.kwin.Effects

The Compositing interface is generated from scriptable elements on the
KWin::Compositor class and the Compositor is exported as /Compositor.
It provides the general Compositing related D-Bus methods like whether
the compositor is active and toggling and so on.

The Effects interface is generated from scriptable elements on the
KWin::EffectsHandlerImpl class and the instance is exported as /Effects.
It provides all the effects related D-Bus methods like loading an effect
or the list of all effects.

This removes the need to have all these methods provided on the global
org.kde.KWin interface. For backwards compatibility they are kept, but
no longer provided by the Workspace class. Instead a new DBusInterface
is generated which wrapps the calls and delegates it to one of our three
related Singleton objects:
* Workspace
* Compositor
* EffectsHandlerImpl

7497ef9148 Make the Compositor a proper Singleton
The Compositor class actually behaves like a Singleton so it should be
one. Therefore four static methods are added:
* self() to access the Singleton
* createCompositor() to be used by Workspace to create the instance
* isCreated() to have a simple check whether the Singleton is already
  created
* compositing() as a shortcut to test whether the compositor has been
  created and is active

The isCreated() check is actually required as especially Clients might
be created and trying to access the Compositor before it is setup.

93564b7004 kwin: Fix build failure regarding QElapsedTimer.
It seems not all Qt installs will automatically #include QElapsedTimer
from QtCore/QTimer, this caused a build failure on my system and on a
RHEL 6.2 VM I've been testing on.

Checking the Qt docs, QBasicTimer also has a separate include so
although this didn't cause a build failure, I've thrown in its
separate #include as well. I have not checked for other #include errors,
and a very quick search on b.k.o for bugs mentioning "build" did not
return any bugs to close.

I'm pretty sure this build failure applies only to master but I haven't
checked thoroughly.

62c4d449f5 Use signals'n'slots instead of deep function call into Compositor
For most actions where the compositor needs to perform an action
(e.g. scheduling another repaint) signals were already emitted.
So it's easier to just connect the signals to the Compositor
which in turn makes the code much more readable.

All signals are connected from the Workspace when either the
Compositor gets constructed or a Toplevel gets created.

0f2e5e61a8 Move reinitializeCompositing and restartKWin into the Compositor
The DBus signal which causes KWin to reinitialize the Compositor
is moved into the Compositor as everything can be handled from
there as well. This comes together with moving the restartKWin
functionality into the Compositor as it is only relevant there.
Restart will only happen if the wrong Qt graphicssystem is used
for the chosen compositing backend.

df6c423962 Connect the lost CM Ownership directly to finish slot
All the custom slot did was printing a debug statement and
calling finish. We do not need this debug statement. The times
of Compositors not part of Window Managers are over, so it is
extremely unlikely that we lose the ownership without KWin
going down anyway.

28a5487d4d Drop compositing prefixes from methods and variables in Compositor
Yes everything in the Compositor is related to compositing, no
need to state it everywhere.

2d954a6bf3 Make the Scene owned by the Compositor
The Scene has always been created and destroyed inside what is
now the split out compositor. Which means it is actually owned
by the Compositor. The static pointer has never been needed
inside KWin core. Access to the Scene is not required for the
Window Manager. The only real usage is in the EffectsHandlerImpl
and in utils.h to provide a convenient way to figure out whether
compositing is currently active (scene != NULL).

The EffectsHandlerImpl gets also created by the Compositor after
the Scene is created and gets deleted just before the Scene gets
deleted. This allows to inject the Scene into the EffectsHandlerImpl
to resolve the static access in this class.

The convenient way to access the compositing() in utils.h had
to go. To provide the same feature the Compositor provides a
hasScene() access which has the same behavior as the old method.
In order to keep the code changes small in Workspace and Toplevel
a new method compositing() is defined which properly resolves
the state. A disadvantage is that this can no longer be inlined
and consists of several method calls and pointer checks.

523b537962 Use singleton accessor for Workspace in Compositor
Replaces the member variable which is actually not needed as a
pointer to the Workspace can always be retrieved through the
singleton accessor of Workspace.

f3739469a2 Move Workspace's compositing functions to own class Compositor
All Workspace functions which were implemented in the file composite.cpp
were moved to an own class Compositor. The header entries were moved as well.
All functions calls are updated.
