* "" needs to be wrapped in QStringLiteral
* QString::fromUtf8 needed for const char* and QByteArray
* QByteArray::constData() needed to get to the const char*
Instead of wrapping for exactly one case let's just use the proper
function calls and get rid of all those methods marked as "remove KDE4"
and "backwards compatibility".

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.
The hack used to be used to hide windows before they get embedded into
another window. This has been wrong on multiple levels:
1. it does not belong into a window manager - the window should take care
of this by itself
2. Window title is not a proper way to identify windows
3. Using D-Bus to inform an X11 window manager about windows which should
not get managed is rather strange
4. The hack only works with KWin, but not with any other X Window Manager
5. Windows identified with this hack still appear in Alt+Tab, that is
they are managed after all. Only a flicker is suppressed
6. Such windows are shown in the taskbar which nicely illustrates how
wrong a D-Bus call to the window manager is
That the hack has been introduced for Java Applets in KHTML also shows
that this is wrong. Why does Gecko and WebKit not need such a hack? Why
is KHTML tied so closely to X11 and KWin? Having a hack for a technology
which is obsoleted (Java Applets) and shouldn't be used due to security
issues is another reason to no longer support this hack. This usage has
been removed from KHTML as of 67939b1 of kdelibs git repo.

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.
It is more Placement related and does not really fit into geometry given
that it only calls methods on Placement. It probably only was inside
Workspace due to being part of the DBus interface. The DBus methods are
used by external components so it needs to stay.
The DBus Wrapper is now calling the methods on the singleton Placement
directly, so no need in Workspace anymore.
It is not used anywhere inside KWin at all and the DBus method is not
used anywhere inside KDE's repositories (according to lxr). Because of
that marked as deprecated and going to die with Qt 5.

Two new interfaces are introduced:
* org.kde.kwin.Compositing
* org.kde.kwin.Effects
The Compositing interface is generated from scriptable elements on the
KWin::Compositor class and the Compositor is exported as /Compositor.
It provides the general Compositing related D-Bus methods like whether
the compositor is active and toggling and so on.
The Effects interface is generated from scriptable elements on the
KWin::EffectsHandlerImpl class and the instance is exported as /Effects.
It provides all the effects related D-Bus methods like loading an effect
or the list of all effects.
This removes the need to have all these methods provided on the global
org.kde.KWin interface. For backwards compatibility they are kept, but
no longer provided by the Workspace class. Instead a new DBusInterface
is generated which wrapps the calls and delegates it to one of our three
related Singleton objects:
* Workspace
* Compositor
* EffectsHandlerImpl
