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.

If the ClientModel does not contain any Clients, which can
happen if there is no desktop window, accessing the data of a
ModelIndex returns an invalid QVariant. Because of that it
needs to be ensured that the QVariant is valid before trying to
cast it to a Client Pointer.

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.

If there are no windows for Alt+Tab the Show Desktop entry
is shown. This works better with both layouts and effects.
Before this change effects were not activated at all but
a fallback to the layouts was used. Concerning the layouts
some looked rather bad. E.g. Thumbnails did not show a
thumbnail but a legacy text had been shown.
When a window gets added to the empty list, the show desktop
window is removed and consequently when the last window goes
away the show desktop entry is added again.
There is a not considered corner case: if there is no desktop
window, the show desktop functionality is not available and
the behavior is unfortunately undefined. It is a corner case
as we can expect that there is always a desktop window when
using KWin. E.g. there is either Plasma Desktop or Netbook
and on PA there is always at least one window.

The grabbed key events inside TabBox are forwarded to the declarative
view which passes it to the normal keyPressedEvent() method. This
allows the QML files to handle keyboard navigation themselves.
The views support key navigation natively, though this cannot be
used as we need to update the ModelIndex when a new item is selected.
Also there seems to be a problem if the tabbox is shown again, in
that case the focus seems to be somehow lost. Because of that the
navigation is handled in the Item embedding the list.

This includes the delegates, the layout configuration for the delegates
and the custom view for the TabBox.
This can now finally be done as desktop tabbox is based on QML, too.
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.
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.
All the default layouts (informative, compact, text, small and big icons)
are rewritten in QML and replace the ListView used before. The old code
is still around for the desktop switching modes which are not yet ported.
Next steps include to update the configuration module to not show now
obsoleted settings as well as providing a better way to choose the layout.

When effects are active we never need the "classic" TabBoxView.
Nevertheless it was always created when KWin started up. By
delaying the creation some ressources should be saved if the user
only uses effects.

This should improve the KWin startup time as some IO is moved
into another thread. Till the config is loaded the TabBox blocks
all signals to activate the TabBox, but it is unlikely that alt+tab
is tried to be used before KWin is completely started.
This change unduplicates some code and merges it into one class
allowing us to use an replacement effect for the outline in
future.
