The change to have stacking order containing
Toplevel inestead of Clients (431aad6d6994695e72697fcc3299ec2cb6f0684e)
introduced possible crashers as recognized in:
http://git.reviewboard.kde.org/r/104519/#review12714
This change fixes these issues by adding missing
null pointer checks after casting to Client.

Workspace::addDeleted swaps the Client with the Deleted in the
stacking order. For Unmanaged windows the Deleted is appended
to the stacking order which is the same layer.
When the deleted is closed the window is removed from the stacking
order.
The result is that a deleted window is no longer raised above all
other clients.

The common usage of stacking order is to loop through
the list and find a specific Client. All these usages
still need to find a Client. For that the loops are
adjusted to first cast the Toplevel into a Client and
continue if the current item is no Client.
At the moment all entries in the stacking order should
still be Clients as the Deleted are not yet added.
This can be used by (autohiding) panels to get the panel above other keepAbove windows
Since the activation still impact the stacking order, the panel should still use
QWidget::raise() or eventually KWindowSystem::raiseWindow(WId win) to (forcefully) get the panel on top.
NOTICE: latter is actually a call for tools like pagers and taskbars, don't abuse it but
preferably use QWidget::raise() instead. Unless the user doesn't type into the keepAbove window while
activating the panel at the same time, this *should* be sufficient.

This input-only window is used to capture events above the
client window and preventing them from reaching the client.
It is currently used to enlarge the borders by an invisible
amount, using the ExtendedBorderRegion provided by the
decoration.
The code was updated to use a QVector for the screen edge windows instead of
an ordinary Window array. The getter method windows() was updated to return
now this QVector.
In the method propagateClients() in layers.cpp the newWindowStack QVector is
filled by iteration through the screen edge windows and only adding Windows that
are not None.
Since the functions were moved from Workspace to its own class ScreenEdge
and the functionality was formerly called ElectricWindows, the functions still
had the old names. They are now consistenly renamed without redundand naming.
The function calls were updated as well in all classes where ScreenEdge is used.
Since the functionality of screen edge handling was moved to its own class,
the screen edge windows are now provided by the getter method screenEdgeWindows().
The new getter method screenEdgeWindows() returns a reference to a QVector,
which includes the screen edge windows.
The Workspace method propagateClients() implemented in layers.cpp needs these
screen edge windows to restack the windows. The code was also modified to use
QVector instead of a Window array.
This commit change the screen edge function calls to be called in the
new class ScreenEdge. The old methods are still in Workspace and will
be removed in a further commit.
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.

Ensure electric borders are above effect input windows after blocking stacking order updates.

in case the new stacking order is needed before kwin gets the matching event,
due to X being asynchronous.

and not be slowed down by going through compositing. Turned on and no UI option
in the naive hope that it won't cause any real problems. Maybe effects doing
window previews should get API to suspend unredirect though.

window to be focusable is probably unnecessary and this was breaking
because of the skiptasbar flag.
