When a client becomes active on a screen with a fullscreen
window on the ActiveLayer, that window needs to be withdrawn
from the active layer explicitly as it does not get this update
with deactivation.

For all the decoration updates called from Client into the decoration we
also have a signal being emitted. So turning the pure virtual public
functions into slots means we can just connect our existing signals and
get rid off the deep function calls.
The keepAbove/Below signals are changed to take a boolean argument as
needed by KDecoration and a few emitted signals are moved to a better
fitting location.

Split out the default and installed colormap from Workspace and put them
into an own class Colormaps.
The method updateColormaps is replaced by a slot update in Colormaps and
activeClientChanged signal is connected to this slot.
At the same time the colormap related code is straight forward ported to
xcb.

It's not a typical singleton as the ctor is not taking a Workspace* and
needs addtional data to be passed to NETRootInfo.
All the initialization code is moved to RootInfo::create() and the tear-
down code is moved to RootInfo::destroyed(). This includes the support
window which used to be a member of Workspace. It's only needed by
RootInfo, so there is no need to have the ownership inside Workspace.
Instead of using a QWidget we just create a normal window through xcb.
It gets destroyed again in the tear-down code after the RootInfo got
destroyed.

Main motivation for this change is that it's unhandy to have the class
definition in workspace.h and client.h while the implementation is in
events.cpp although nothing in events.cpp uses it directly.
By getting it out of workspace.h we get the header a little bit smaller
which should improve compile time given that it's included almost
everywhere.
In events.cpp the enum usage is changed to NETWinInfo as that's the class
where they are defined.
RootInfo does no longer hold a workspace pointer. Where it's needed it
uses the singleton accessor of Workspace.

Overall all notifications except compositing suspended by DBus were
configured by default to not have any action. This means all the time we
emit a notification we keep DBus and KDED busy for nothing.
All the cases when a notification is triggered ire also exported to
KWin scripting, so if one really needs to handle something in case a
window is moved, it could be done through a KWin script with much more
context about the event.

Following the approaches of other split out functionality Screens is a
singleton class created by Workspace.
The class takes over the responsibility for:
* screenChanged signal delayed by timer
* number of screens
* geometry of given screen
* active screen
* config option for active screen follows mouse
The class contains a small abstraction layer and has a concrete subclass
wrapping around QDesktopWidget, but the idea is to go more low level and
interact with XRandR directly to get more detailed information.
All over KWin the usage from QDesktopWidget is ported over to the new
Screens class.

All activities related code moves into new singleton class Activities.
This class gets only included into the build if the build option is
enabled which means there are less ifdefs all over the code and it also
handles better the moc doesn't like ifdef case.
The class holds the list of open and all activites, the current and the
previous activity and the KActivities::Controller. It also emits the
signals for any activities related changes.
Workspace still contains some activities related code. That is the
adjustment on change of current activity. Nevertheless the code looks
much cleaner now and does not contain the confusing naming conflict with
takeActivity() which existed before.
In all the places where Activities got used the code got adjusted and
quite often the ifdef got added with a fallback for the disabled case.
Many headers included KLocale to use i18n and co. But those methods are
defined in KLocalizedString and not in KLocale.
With KF5 klocale.h does no longer include KLocalizedString causing lots
of compile errors.
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.

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).

The ownership for virtual desktops is moved from Workspace into a new
VirtualDesktopManager. The manager is responsible for providing the count
of virtual desktops and keeping track of the currently used virtual
desktop.
All methods related to moving between desktops are also moved from
Workspace to the new manager, though all methods related to Clients on
Virtual Desktops remain in Workspace for the time being. This is to have
the new manager as independent from KWin core as possible.
An rather important change for the handling of virtual desktops is that
the count and the id of a desktop is now an unsinged integer instead of
an integer. The reason for that is that we cannot have a negative count
of desktops as well as it is not possible to be on a desktop with a
negative identifier.
In that regard it is important to remember that a Client can be on a
desktop with a negative identifier. The special value for a Client being
on all desktops is handled by using -1 as a desktop. For the time being
this is not adjusted but instead of comparing the virtual desktop ids one
should prefer to use the convenient methods like isOnDesktop and
isOnAllDesktops. This would allow in future to internally change the
representation for on all desktops.
This allows me to use all applications in a Yakuake-like method.
I can define a shortcut for an application, press it, window shows up, do my work, press it again and it hides.
This is specifically good for a Text Editor<-->Browser switching workflow.
Also my first kwin patch.
For most actions where the compositor needs to perform an action
(e.g. scheduling another repaint) signals were already emitted.
So it's easier to just connect the signals to the Compositor
which in turn makes the code much more readable.
All signals are connected from the Workspace when either the
Compositor gets constructed or a Toplevel gets created.
All Workspace functions which were implemented in the file composite.cpp
were moved to an own class Compositor. The header entries were moved as well.
All functions calls are updated.
All methods and variables related to the User Actions Menu
(rmb window deco, Alt+F3) is moved out of the Workspace class
into an own UserActionsMenu class.
The class needs only a very small public interface containing
methods to show the menu for a Client, closing the menu and
discarding the menu. Everything else is actually private to the
implementation which is one of the reasons why it makes sense
to split the functionality out of the Workspace class.
As a result the methods and variables have more sane names and
the variable names are standardized.

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.
Client has a property for demands attention and Workspace
is emitting a signal whenever the demands attention state
of any Client changes.

Dropping the wrapper around Client and just exporting the Client's
properties. This breaks all existing scripts as it's now e.g.:
client.caption
instead of
client.caption()
But the first one is the more natural one for JavaScript and also
for everyone writing QML as well.
Setters and signals are mostly still missing in client. Other parts
like ClientGroup must be converted to properties, too.
Instead of directly calling notifyTilingWindowActivated() the signal
clientActivated() is used and connected. Including tiling.h is no longer
needed in activation.cpp.
This initial commit introduces a new class Tiling. It is provided by
the files tiling/tiling.h and tiling/tiling.cpp. It covers all the
Tiling functionality which was provided by Workspace. In this initial
commit, all the functions were just moved and adjusted.
A new member variable m_tiling is introduced to Workspace, which
makes the new class Tiling accessible from Workspace.
The Tiling pointer is created in the constructor and deleted in
the deconstructor. Also a getter method tiling() is provided.
All calls from other classes are updated to use the methods in class
Tiling now.
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.

Drawbound was nowadays only used when compositing is disabled.
For the composited case, the drawbound was replaced by the resize
effect and in fact we should always just use the resize effect.
REVIEW: 101411
EffectsHandlerImpl connects to the Workspace signal clientActivated.
The emitting of the signal is slightly moved from before the activation logic
to after the activation logic. This might change behavior in the scripting
component, but the previous code looked wrong.
