Removes the ElectricAction for ShowDashboard and the relevant code
in screenedges and the KCM.
Also a leftover in the glide effect.

xcbutils.h has quite a few inline only implementations such as Xcb::Atom,
the Wrappers, Xcb::Window and the convenient methods. Thus there is
nothing wrong with using it from the built-in Effects.
Xcb::Atom is used in Glide and Logout Effect to get the atom. To keep the
logic of the existing code it got extended by a bool isValid() which
gets the reply and returns true if the atom is set.

So far the effects could just use the connection() and rootWindow()
provided by kwinglobals. Thus an internal detail from KWin core is
accessed directly.
To be more consistent with the rest of the API it's wrapped through the
EffectsHandler and with a convenient method in Effect.
The connection() is provided as xcbConnection() to free the very generic
name connection which could create confusion once we provide a wayland
connection to the Effects.
The rootWindow() is provided as x11RootWindow() to indicate that it is
for the X11 world.

Affected effects
* Blur and Contrast Shader to get atom name
* Glide effect for the slide atom
* startupfeedback for cursor size - read from config now and cached
* showfps used an xsync, replaced by flush
* logout effect for creating hack items

Most is just switched to the ::read(). That should be enough for all the
Effects which have a KSharedConfig::Ptr underneath. If not we just need
to find a good place to put the reload.
As all effects have always been compiled into the same .so file it's
questionable whether resolving the effects through a library is useful
at all. By linking against the built-in effects we gain the following
advantages:
* don't have to load/unload the KLibrary
* don't have to resolve the create, supported and enabled functions
* no version check required
* no dependency resolving (effects don't use it)
* remove the KWIN_EFFECT macros from the effects
All the effects are now registered in an effects_builtins file which
maps the name to a factory method and supported or enabled by default
methods.
During loading the effects we first check whether there is a built-in
effect by the given name and make a shortcut to create it through that.
If that's not possible the normal plugin loading is used.
Completely unscientific testing [1] showed an improvement of almost 10
msec during loading all the effects I use.
[1] QElapsedTimer around the loading code, start kwin five times, take
average.

* "" needs to be wrapped in QStringLiteral
* QString::fromUtf8 needed for const char* and QByteArray
* QByteArray::constData() needed to get to the const char*
This method can be used to get the animationTime in case a configuration
class generated through KConfigXT is used. In general the configuration
stores the magic value 0 for a property "duration". This magic value
indicates that a hard-coded default value should be used.
So the common logic to test the stored value for 0 and then either pass
the stored value or the default value to animationTime is encapsulated
in this method in a generic way.
A MyEffect can use it in the following way:
animationTime<MyEffectConfig>(200);

The CompositingType enum turns into flags and two new values are
introduced: OpenGL1Compositing and OpenGL2Compositing.
Those new values are or-ed to OpenGLCompositing so that a simple check
for the flag OpenGLCompositing works in case of one of those two new
values. To make the generic check for OpenGL compositing easier a method
in EffectsHandler is introduced to just check for this.
The scenes now return either OpenGL1Compositing or OpenGL2Compositing
depending on which Scene implementation. None returns OpenGLCompositing.
The public member variables for opacity, saturation and brightness
are removed in favor for getter and setters. The variables are
moved into a private class. Those are now qreal instead of double.
To make usage inside the effects easier a multiply method is added
which multiplies the current value with passed in factor and returns
the new value in a functional programming style.

Each effect is able to declare itself as currently being active,
that is transforming windows or painting or screen or doing anything
during the current rendered frame.
This change eliminates the hottest path inside KWin identified by
callgrind.

Since the funtionality of TopMenu did no longer work in KDE4 this feature was
removed from Workspace. Every reference to it was removed as well as commentaries
and documentation.

Warnings were:
glide.h:74:16: warning: possible problem detected in invocation of delete operator:
glide.h:74:16: warning: invalid use of incomplete type 'struct QTimeLine'
glide.h:28:7: warning: forward declaration of 'struct QTimeLine'
glide.h:74:16: note: neither the destructor nor the class-specific operator delete will be called, even if they are declared when the class is defined.
The KWin::TimeLine class was only a small wrapper around QTimeLine
without adding anything to QTimeLine what is not present in QTimeLine.
The initial idea was to make it possible to provide more curve shapes.
This is now obsoleted by Qt shipping more useful curves with QTimeLine.
So let's clean up a little bit and use QTimeLine directly instead of
the small wrapper.
All effects are adjusted to use QTimeLine directly.
Client and Unmanaged use a signal to notify that they are about to be closed.
The EffectsHandlerImpl is connected to those signals and emits the appropriate
windowClosed signal to which the effects are connected.
All previously existing windowAdded methods are renamed to slotWindowAdded.
EffectsHandlerImpl is connected to Workspace's clientAdded signal, which is
emitted a little bit earlier than the previous direct method call. This might
change behavior.
Another signal is added to Workspace to signal that an unmanaged is added.
* use TimeLine data memeber instead pointer to prevent leaking
* only setTransformed() if there's really a current animation, not if "a window we know is mapped"
* therefore use a poperty to know whether the effect manages a deleted window
* set the TRANSFORMED flag in prePaintWindow as it should be
