I don't like to do it, but it's better than users getting a bad
performance experience.
The change should be reverted once the issue is identified and fixed.

displayWidth/Height() are rewritten on top of XCB. rootWindow() and
xTime() return xcb datatype instead of XLib datatype.
Unfortunatelly it's not possible to cache the result for displayWidth and
Height, but getting the default screen is cached and provided in another
method.

Where possible it is changed to Cursor::pos(), where we cannot use the
Cursor class (e.g. Aurorae) we can at least try to limit the usage to
prevent roundtrips to the X server.

To support this feature the DesktopModel is turned into a tree model with
the desktops on the root level and the Client's at the next level.
In the view a VisualDataModel is used which kind of supports a tree model
by setting the root index. A list view is added underneath all the
desktops showing the icons of the windows on the desktop one switches to.

The Client::cursor property is changed from QCursor to Qt::CursorShape
and renamed to m_cursor (as all usages are adjusted).
This property is mostly used to define the cursor on e.g. the extended
deco border window. To make this easier a XDefineCursor replacement is
added to xcbutils.h both as a static method and as a member function to
Xcb::Window.
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.
The code is rewritten in a way to replace the local event loop with event
filtering done in the normal way through events.cpp. Therefore instead of
creating a KillWindow whenever it's needed, there is one available in
Workspace which will be reused on next invocation.
The responsible events are passed from events.cpp to KillWindow for
processing.
In order to port the keycode to symbol to XCB, KWin now finds
xcb_keysyms and links it.
To get the right cursor KWin now links the XCursor library which is
unfortunatelly an XLib based library, but there seems to be no XCB
replacement.
This includes:
* getting cursor image through xcb_xfixes
* using xcb_image_get for reading screen content in xrender case
* using xcb_put_image to upload the generated screenshot into shared xpix
Overall this means that QPixmap as an X Pixmap wrapper is no longer used.
The conversion from xcb_image_t to QImage still needs some code for not
matching byte order. I'm a little bit unsure about adding the code as I
would not be able to test it.

Space is a valid shortcut part. E.g. "Volume Up".
KConfig update script for 4.11 is added to migrate existing and erroneous
rules taking into account that space is a valid key.

The regular expression is only matching shortcuts of the kind:
ctrl+(123)
which does not match a normal shortcut like:
ctrl+x
So if multiple shortcuts are specified, one without multiple options
has not been accepted.
* use xcb_fixes_foo
* drop QX11Info - we don't need it in the effects
* use QScopedPointer for GLTexture/XRenderPicture
* remove commented code
* use kDebug instead of qDebug
Of course XCursor library is still used as there is no XCB replacement.
What could be considered is adding a getCursor hook into the
EffectsHandler as also the ScreenShot Effect is getting the cursor and
using XCursor doesn't seem future proof to me ;-)
Sorry for putting everything into one commit.

ScreenEdgesEffect failed compiling, mouseclick and zoom are yelling
warnings.
Compiling is tested with XRender enabled, for the disabled test I need to
wait for my Jenkins installation ;-)
The new class FocusChain manages two different kind of focus chains.
First of all there is a most recently used focus chain which is primarily
used for TabBox.
Then there is one focus chain per virtual desktop. These chains are used
to determine which Client needs to be activated when e.g. switching to a
virtual desktop.
The individual chains are implemented as a simple QList of Client* with
the most recently used Client as the last element. That way one can see
it as a LIFO like structure.
The desktop focus chains are internally represented as a hash with the id
of the virtual desktop as the key and a list as described as the value.
FocusChain is a singleton which provides some methods to manipulate the
chains and to get a specific Client for a task (e.g. TabBox).
While splitting out the code some unused code inside TabBox got removed
as well as some activities related code (windows cannot be moved while
switching activities).

* no more binding loops - yeah for anchoring
* properly update sizes when switching screens
* properly handle case layout indicator enabled/disabled
* connect to desktop changed and reset desktop model
* set a maximum width/height of 0.8 of screen
Most interesting change is the moving of
visible = true;
to the beginning of the block which updates the layout. Without that
all the changes are ignored resulting in the incorrect size on screen
change.
The disadvantage of that is that the OSD is shown before the layout is
adjusted. But it's considerable minor given that it should be just one
frame.

In case the extension is not present eglQuerySurface returns EGL_FALSE
when querying for EGL_POST_SUB_BUFFER_SUPPORTED_NV and sets an
EGL_BAD_ATTRIBUTE error state. If this is the case it's not an error we
should abort on, but one we should ignore as it's the same as extension
not supported.

A window can be "maximized" despite it's position is fixed.
Most obvioulsy for a corresponding of "0", but also in other
cases. The window can still be resized, some size is the
maximum one and there's no reason to prevent the shortcut of
this state.

instead of just checking whether the decorated client will be bigger
than the workarea and take that as reason to maximize it, we will not do
so if it's smaller than the full are and the managed client bigger than
the screen (because it makes sense for the user to move it around and the
requested dimension is out of what the client could have stored when closing
maximized)

Using Xcb::Window to manage the xcb_window_t and simplify the code - no
longer need to check whether the input_window is valid before calling e.g.
map, as that's handled in Xcb::Window.
One XLib usage for setting cursor is still present. This will be ported
once all the QCursor::handle() get removed.

Since the introduction of VirtualDesktopManager we do have a signal
emitted when the desktop layout changes which we can use as NOTIFY for
