In the Wayland world we need to have a compositor. This means we have to
enforce that the compositor is running. If the setup fails we have to
quit, because it doesn't make any sense any more to be running.
A new method requiresCompositing() is added to the Application. If it
returns true the useCompositing option will always return true and the
unredirect fullscreen option will always return false. That way
compositing is enforced at startup and cannot end by unredirecting.
In addition this method is checked if actions are performed which would
suspend compositing. E.g. the shortcut to toggle compositing. Restarting
the compositor is still possible in order to change the selected
compositing backend without a restart. But if it fails KWin will quit.
Returns true if the OperationMode requires KWin to composite to a
Wayland surface. This replaces the checks for the WaylandBackend or env
variable used so far in the construction of the Scene.
This enum describes how KWin is operating with the available windowing
systems. By default KWin is using the OperationModeX11, but if the
Wayland backend gets started KWin is using the OperationModeWaylandAndX11
This will be extended in future when XWayland and Wayland only become
viable options.
The idea is that we can use the Application instance as a place to put
global information which should not go into kwinglobals. That is core
global things.
The crash count checking does not depend on whether or not we will
be able to claim the window manager selection. As claiming the selection
can take up to one second we should try to get as many checks which do
not depend on it out.
Done in one step as it requires changes which are better suited with a
QApplication.
To not need to parte the QCommandLineParser around the needed arguments
are added to the KWin::Application through setters and the crash count
is available through a static getter/setter pair.
Forwards all xcb events to Workspace::workspaceEvent() which got changed
to process xcb events instead of XEvents. So far all handling is
disabled. Will be re-enabled step by step in the following patches.
being v2+ (right now it says just GPL, which according to GPL itself
means any GPL). Decoration clients will come later.

// If the system tray gets destroyed, the system tray
// icons automatically get unmapped, reparented and mapped
// again to the closest non-client ancestor due to
// QXEmbed's SaveSet feature. Unfortunatly with kicker
// this closest ancestor is not the root window, but our
// decoration, so we reparent explicitely back to the root
// window.
2. Removed popupinfo feature for now. The feature is a great idea, but the
implementation was too much copy&paste and code duplication with the
tab box. Plus it was buggy (no vertical center alignment) and contained
many unused codelines.
3. Fixed and simplified the session management handling (thanks to
KSessionManaged in libkdecore). This way we actually get a proper
discardCommand generated by KApplication, something that was missing
previously.
