A factory is supposed to emit this signal whenever the decorations
need to be recrated. The DecorationPlugins inside KWin Core connect
to the signal and recreate the decorations.
This signal is supposed to replace the reset method which encoded
this information in the return value and which is already ignored.
The changed mask is going to be replaced by more specific signals so
we don't need to calculate the change mask in KWin core anymore.
We still need to call reset in the decoration plugin to check whether
a new decoration library needs to be loaded.
There used to be an own action collection in KDE 3 times for the
block global shortcuts shortcut. But the code ws disabled and by
that I didn't see it during removing the global shortcuts blocking.
And it explains why the global shortcut blocking didn't work.
Done in one step as it requires changes which are better suited with a
QApplication.
To not need to parte the QCommandLineParser around the needed arguments
are added to the KWin::Application through setters and the crash count
is available through a static getter/setter pair.
Wrapped in xcbutils.
In addition the check whether another WM is running in main.cpp is
improved by doing a checked request and directly checking for the
error. If there is an error, KWin puts out an error message and
quits.
Client::releaseClient() deletes all Client objects
referenced by stacking_order, thus those pointers
dangle and everything trying to touch it died an ugly death.

Using a QTimer to move the resize/move related code to the end of the
event queue. In case there is another motion event in the queue it will
cancel the timer.
* "" needs to be wrapped in QStringLiteral
* QString::fromUtf8 needed for const char* and QByteArray
* QByteArray::constData() needed to get to the const char*
Qt 5 only supports raster which means our pixmaps are always non native,
so we don't need the Extension information any more and can drop all
special code handling for mapping a native QPixmap to an X11 pixmap.
fixing bug by deferring the deletion and removal of the
deleted to the next event cycle had the side effect that
this now happens in the event cycle of the compositor
restart, which was deferred to avoid precisely that...
so the test is now moved to the removal of the deleted
which got an additional flag wasClient to avoid calling
this action for each and every tooltip (and might be usable
elsewise)

This shortcut did not make any sense to me, because you could block the
global shortcuts for KWin, but not re-enable them again. So once blocked,
it was blocked for ever till kwin --replace &.
This is in opposite to the commit message which introduced it
(see BUG 108961).

Unfortunately only information available through the factory can be read.
As Factory is not a QObject we cannot use the Q_SLOT trick to get further
information dynamically from the loaded decoration plugin.

Split out the default and installed colormap from Workspace and put them
into an own class Colormaps.
The method updateColormaps is replaced by a slot update in Colormaps and
activeClientChanged signal is connected to this slot.
At the same time the colormap related code is straight forward ported to
xcb.

It's not a typical singleton as the ctor is not taking a Workspace* and
needs addtional data to be passed to NETRootInfo.
All the initialization code is moved to RootInfo::create() and the tear-
down code is moved to RootInfo::destroyed(). This includes the support
window which used to be a member of Workspace. It's only needed by
RootInfo, so there is no need to have the ownership inside Workspace.
Instead of using a QWidget we just create a normal window through xcb.
It gets destroyed again in the tear-down code after the RootInfo got
destroyed.

Main motivation for this change is that it's unhandy to have the class
definition in workspace.h and client.h while the implementation is in
events.cpp although nothing in events.cpp uses it directly.
By getting it out of workspace.h we get the header a little bit smaller
which should improve compile time given that it's included almost
everywhere.
In events.cpp the enum usage is changed to NETWinInfo as that's the class
where they are defined.
RootInfo does no longer hold a workspace pointer. Where it's needed it
uses the singleton accessor of Workspace.

Workspace is hardly interacting with Rules and all the Rules related code
is already in rules.cpp. This highly qualifies to move all the code out
of Workspace and improve the names.

The non-composited part handles the showWithX case with the four small
windows. The composited part shows a translucent QWidget with the
FrameSvg as done by the selection effect frame.
Outline connects to the Compositor toggled signal to switch the mode if
compositing gets suspended/resumed. This works fine also in the case that
the switch happens while the outline is shown. To support this Outline
is now a QObject and created with Workspace as a parent.
Given that the Outline handles both cases by itself, the outline effect
is no longer needed and is dropped together with all the hooks into the
effect system.
Overall all notifications except compositing suspended by DBus were
configured by default to not have any action. This means all the time we
emit a notification we keep DBus and KDED busy for nothing.
All the cases when a notification is triggered ire also exported to
KWin scripting, so if one really needs to handle something in case a
window is moved, it could be done through a KWin script with much more
context about the event.

Following the approaches of other split out functionality Screens is a
singleton class created by Workspace.
The class takes over the responsibility for:
* screenChanged signal delayed by timer
* number of screens
* geometry of given screen
* active screen
* config option for active screen follows mouse
The class contains a small abstraction layer and has a concrete subclass
wrapping around QDesktopWidget, but the idea is to go more low level and
interact with XRandR directly to get more detailed information.
All over KWin the usage from QDesktopWidget is ported over to the new
Screens class.

This allows to move the slot to reset the decoration when compositing
got toggled from Workspace to DecorationPlugin and the custom cleanup
is no longer needed.

The define KWIN_SINGLETON adds to a class definition:
public:
static Foo *create(QObject *parent = 0);
static Foo *self() { return s_self; }
protected:
explicit Foo(QObject *parent = 0);
private:
static Foo *s_self;
There is an additional define KWIN_SINGLETON_VARIABLE to set a different
name than s_self.
The define KWIN_SINGLETON_FACTORY can be used to generate the create
method. It expands to:
Foo *Foo::s_self = 0;
Foo *Foo::create(QObject *parent)
{
Q_ASSERT(!s_self);
s_self = new Foo(parent);
return s_self;
}
In addition there are defines to again set a different variable name and
to create an object of another inheriting class.
All the classes currently using this pattern are adjusted to use these
new defines. In a few places the name was adjusted. E.g. in Compositor
the factory method was called createCompositor instead of create.
