It's only used from useractions.cpp which means that it's not the best
fit in utils. We can see the problems with it given that it was in an
ifdef and it included quite some headers into everything.

It's an option doing pretty much the same as the highlight of selected
window option. But it is known to conflict especially with some Plasma
themes.

There is only one instance hold by Workspace which means it should follow
the common approach with ::self and ::create.
The hasTabBox is completely removed as it's rather useless and the same
as the ifdef around the usages any way.

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).

Use xcb to create and manage the X11 backend of Outline. In addition the
used background pixmaps are rendered with XRender instead of using a
QPainter on a QPixmap. This is done because QPixmap is no longer bound to
an X Pixmap.
To create the XRender Picture the available functionality from
kwinxrenderutils is used. To be able to use it in KWin core the compile
option to build without XRender is removed for kwinxrenderutils, but
still supported for effects.
Obviously the port to XCB is not complete as xremderutils itself is still
on XLib.

Most recently used virtual desktop chain is only used in the context of
TabBox and therefore moved into this namespace. KWin uses one desktop
chain for each activity. This is mapped by having multiple DesktopChains.
In addition there is a DesktopChainManager which contains all those
chains which are identified by a QString.
The manager gets connected to the signals emitted by VirtualDesktopManager
for changes in virtual desktops and to signals related to Activities
emitted by Workspace. This means the manager is rather generic as it does
not depend on any other components.
If the start Client is not part of the focus chain the call to
nextClientFocusChain() cannot return the Client again. So the loop break
condition is never reached and as the focus chain is not empty the call
always returns a not null Client which means KWin is caught in an endless
loop.
This change checks that the starting Client is in the focus chain and if
not the first Client of the focus chain is used.

The recently used mode of TabBox uses the active window as the entrance
into the focus chain. If there is no active window it does not find any
Clients. To solve this issue the ClientModel now uses the first entry
of the focus chain in case there is no active window.

Client holds a SharedPointer to the TabBoxClient and only
provides access to a WeakPointer which is passed to TabBox.
ClientModel is adjusted to hold a list of WeakPointers instead
of the direct pointers.
This fixes the following reproducable crash:
1. Configure both primary and secondary TabBox with different
layouts
2. Use primary TabBox
3. Close a window, best the one which used to be active
4. Use secondary TabBox
-> Crash
The reason is that the ClientModel still contains the pointer
to the deleted TabBoxClient in step 3 and while creating the
layout access to the TabBoxClient is needed to get the Client's
icon.
By using the weak pointer it can be ensured that we don't try
to dereference the deleted pointer and prevent the crash.

cppcheck complained about that piece of code and it was not
really good. A TabBoxClient belongs to exactly one Client which
means the setter should for Client should not be there in the
first place and was only used during construction.

Additional TabBox Mode which allows to switch between all open
windows of the current selected application. By default Alt+tilde
is used which is on qwerty just one key above tab. For non-qwerty
layouts the shortcut is unfortunately not convenient.

If the layout name is specified a custom layout config is
passed to the TabBoxHandler with the configured name.
This can be used by Plasma Active to specify the window strip
(overwrites any settings) and for Netbook shell as a replacement
to opening Present Windows Effect.

DBus method to embedd the TabBox into another window. It follows
the geometry changes and keeps a defined offset to the borders of
the parent window.
Required for Plasma Active's window strip.
This is useful in combination of non-modal TabBox through DBus and
window-strip layout. With DBus the non-modal TabBox can be started
and selecting any item on the strip will end TabBox again.
Available through DBus. Be aware that this does not make much
sense, as there is no way to end TabBox mode except through the
DBus interface and this does not yet select the selected window.
Therefore TabBox is changed to be controlled without pressing a
modifier key. Tab and Backtab are valid keys now which can be
used to navigate in the list and return, enter and space can be
used to close the box (and select the client).
The TabBox is exported as object /TabBox on the kwin interface
providing start and close methods and signal when the TabBox got
closed.
