Support for cursor change tracking in KWin::Cursor

KWin::Cursor can track changes to the cursor image. It supports a
start/stop tracking to not handle these events if nobody is interested in
them. When enabled and the cursor image changes a signal is emitted with
the serial number of the new cursor image.

To track cursor image changes xcb_xfixes_select_cursor_input is used (see
XFixes Version 5.0 protocol, section 7).

This could be useful for the zoom effect when it replaces the cursor.

Defines to create the boilerplate code for KWin's singleton classes

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.

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.
