Most windows use the hostname in WM_CLIENT_MACHINE, but there are windows
using the FQDN (for example libreoffice). So instead of "foo" it is
"foo.local.net" or similar. The logic so far has been unable to properly
determine whether windows with FQDN are on the local system.
In order to solve this problem the handling is split out into an own
class which stores the information of hostname and whether it is a local
machine. This is to not query multiple times. To determine whether the
Client is on the local system getaddrinfo is used for the own hostname
and the FQDN provided in WM_CLIENT_MACHINE. If one of the queried
names matches, we know that it is on the local machine. The old logic to
compare the hostname is still used and getaddrinfo is only a fallback in
case hostname does not match.
The problem with getaddrinfo is, that it accesses the network and by that
could block. To circumvent this problem the calls are moved into threads
by using QtConcurrent::run.
Obviously this brings disadvantages. When trying to resolve whether a
Client is on the local machine and a FQDN is used, the information is
initially wrong. The new ClientMachine class emits a signal when the
information that the system is local becomes available, but for some
things this is just too late:
* window rules are already gathered
* Session Management has already taken place
In both cases this is an acceptable loss. For window rules it just needs
a proper matching of the machine in case of localhost (remote hosts are
not affected). And the case of session management is very academic as it
is unlikely that a restoring session contains remote windows.

The Scene has always been created and destroyed inside what is
now the split out compositor. Which means it is actually owned
by the Compositor. The static pointer has never been needed
inside KWin core. Access to the Scene is not required for the
Window Manager. The only real usage is in the EffectsHandlerImpl
and in utils.h to provide a convenient way to figure out whether
compositing is currently active (scene != NULL).
The EffectsHandlerImpl gets also created by the Compositor after
the Scene is created and gets deleted just before the Scene gets
deleted. This allows to inject the Scene into the EffectsHandlerImpl
to resolve the static access in this class.
The convenient way to access the compositing() in utils.h had
to go. To provide the same feature the Compositor provides a
hasScene() access which has the same behavior as the old method.
In order to keep the code changes small in Workspace and Toplevel
a new method compositing() is defined which properly resolves
the state. A disadvantage is that this can no longer be inlined
and consists of several method calls and pointer checks.
This allows to copy the layer to the deleted window in order to
keep the deleted window in the same layer.
Additionally a new layer is added for unmanaged windows.
where the titlebar is still clickable even if it is outside the normal
work area. When struts are added or removed only move the windows that
cover the same area, leave all others untouched. If a strut is removed
on a xinerama screen that is not on the edge of the full desktop area
prevent the windows from being moved offscreen. Prevent struts/panels
from interfering with the movement of windows on other xinerama screens.

at the same time (in other words, only when activating compositing using the kcm).
Currently selfcheck causes bad flicker (due to X mapping the overlay window
for too long?) which looks bad during KDE startup. With this patch, KDE startup
is without any flicker.

@Lubos: Please have a look at commit 863096 too. I accidently commited a
part of this part there. Please have a look at the todo "Add the window
title" and possibly implement it. That would look much nicer in the global
shortcuts kcm.
Btw. There are two shortcuts dialogs in kwin. I haven't change the other
one (kwinrules) because it look it works better with KKeySequenceWidget
doing the message box.

- the NormalState/IconicState things in ICCCM need to match exactly
the real mapping state, so ensure that, no matter how superfluous that is
- extend the option for having live window previews either for all
windows or for only all shown windows (default)

Also slightly redo the #define's for effects, now it's:
- #ifdef KWIN_HAVE_COMPOSITING to check whether there's any compositing support at all
- #ifdef KWIN_HAVE_OPENGL_COMPOSITING to check for OpenGL-based compositing
- #ifdef KWIN_HAVE_XRENDER_COMPOSITING the same for XRender

Plus some small tricks to prevent such windows from interfering.
Only two basic modes are implemented right now.

There's also a kwineffects library now, containing the effects API, which makes it possible to write
third-party effects.
API isn't complete yet and for now just two effects have been converted but I'm working on it :-)
