due to plasma change, shadow is not included by default, hence kwin
tabbox need to handle shadow by itself, and due to kwin is compositor
and have shadow as effects, it's not a good idea to use X property to
pass shadow from kwin to X and to kwin. This change use the old way to
draw shadow side the tabbox, and partly move the blur region setting to
qml.

Fixed krazy warning about invalid ifdef guard in include
Fixed Krazy warning about signal/slot normalization.
fixed Krazy spelling warning in comments.
Removed x10 multiplicative factor when rendering shadow;
added x10 mutiplicative factors for config UIs with respect to what's actually saved in config
file;
remove kconfupdate for shadowoffset.
- move Shadow configuration UI to libs
- removed useDropShadow and useOxygenShadow options, and replaced by activeShadow::enable and inactiveShadow::enable
- use kcfg for decoration configuration. The handling of exceptions requires dedicated readConfig and writeConfig methods, implemented in oxygenutils
- changed sizegrip combobox into a check box and rephrased for clarification
Two helper classes WindowGeometry and WindowAttributes which can be
used to request the geometry and attributes more easily. This is based on
a templated class, taking cookieType, replyType and function pointers to
the request and reply functions as template parameters.
The ctor performs the async request and the reply is stored in a
QSharedPointer. Whenever the reply is needed it is checked whether it
has already been retrieved and if not will block by calling the reply
method. The class provides operator bool() to check whether the reply
succeeded (pointer is not null) and operator->() to directly access the
reply pointer.
Instead of each effect, which needs to announce support, having custom
code to create a property and set it on the root window, there is now a
common API in EffectsHandler to take care of this.
The methods takes care of creating the atom if it has not already done
and set the property on the root window. Furthermore it allows multiple
effects to announce the same property without getting in conflict with
each other.
As a further convenience the property is automatically removed when the
effect is unloaded, so less things an effect author has to care about.

Main motivation for this change except the fact that it doesn't belong
into Workspace is that the screen edges got updated from within setting
the desktop layout which got removed with the introduction of the
VirtualDesktopManager.
The ScreenEdge now keeps some state to be able to correctly unreserve the
electric borders when changes in the configuration are performed. There
is still room for improvement as there are still some deep function calls
from within reconfiguring in Workspace.

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.
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.
