Summary:
And finally nothing inside libkwineffects, libkwinglutils,
libkwinxrenderutils and kwineffect and kwin core uses KWin::display.
We are finally XLib free!
This change drops KWin::display and removes the include to QX11Info from
kwinglobals.h. And the libraries no longer need to link X11Extras. Due
to that removal a few seeming unrelated changes are required to add the
include where needed and linkage to X11Extras.
The biggest change is to x11 platform plugin which still needs the
display and caches it in the Platform and passes it to various places in
a way that the code doesn't need to be adjusted.

Summary:
This change ensures that kwin_wayland does not pull in KCrash. We
don't want and need KCrash in the Wayland case. If KWin crashes the
session goes down - restarting doesn't make any sense, we need to
relogin.
Similar drkonqi just doesn't work as it doesn't have a windowing
system to connect to. After all the windowing system just crashed.
Also the AlternativeWM dialog doesn't make any sense on Wayland.
Similar thought: there is no windowing system to show this nice dialog.
Overall it's better to have system default behavior
(e.g. systemd-coredump) than using KCrash in the very special case of
kwin_wayland.

kwin_x11 now also loads a platform plugin and initializes it.
It doesn't do much except loading it and init it. Though it's also
set up to continue startup only when screens are queried.
The event filter is only used to let Qt compose a QKeyEvent from an
x11 event for grabbed key events. On Wayland we don't need it as we
can generate good QKeyEvents ourself. This means less event processing
as the events no longer need to pass through the
Workspace::workspaceEvent.
In addition it fixes a regression in LockScreenTest::testEffectsKeyboard
caused by the LockScreenEventFilter sending a QKeyEvent to KSldApp.
This event got intercepted by the global event filter making the test
rightfully fail.
We don't want to actively release claims on segfaults, but then
drkonqi can stop us while we're still holding the WM privs.
=> If KWin performs a crash-restart, it forcefully takes WM privs
(since the old instance shall be replaced for quite sure)

This change enables kactivities integration by default again on both
X11 and Wayland (as kactivities no longer blocks). As we have an
infrastructure to disable kactivities we can also make use of it and
offer a command line switch to disable kactivities. This might be
useful for using KWin outside of Plasma.

We need to destroy the compositor after Xwayland terminated and after
the internal Wayland connection is destroyed. This means when destroying
the Workspace we may no longer destroy the Compositor at the same time.
Also we need to ensure that other tear down functionality doesn't call
into the no longer existing internal client connection.
With this change kwin doesn't crash when exiting with Wayland and/or
X11 windows still open.
Instead of setting our own filter rules we install a categories file
to allow to configure them. This seems to still have them enabled by
default, but should at least give distributions the possibility to
disable logging by default.
Setting this means we get scaled screen geometry from Qt, and everything
becomes confusing when commmunicating with apps that might not have
this set.
As we use plasma units for UI everything is scaled anyway.

This reorders the startup sequence quite a bit:
1. Create QAbstractEventDispatcher and install it on QCoreApplication
2. Create Application
3. Start Xwayland, use thread to get when its ready
4. Create xcb connection
5. perform startup
For using the wayland QPA it needs a patch in QtWayland which will be
part of Qt 5.4.2, otherwise it blocks.
Adjust the KWIN_DBUS_SERVICE_SUFFIX env variable in a multi-head
scenario instead of adjusting the "org.kde.kwin" DBus service which
we actually don't use in 5.x any more.

All of kwin except the main function goes into a new (private) library
called kwin. Two new kdeinit_executables are created:
* kwin_x11
* kwin_wayland
Both only use a dedicated main_x11.cpp and main_wayland.cpp with the
main function and a KWin::Application subclass and linking the new
kwin library.
The main idea behind this is to be able to perform more sane sanity
checks. E.g. on Wayland we don't need to first test whether we can
create an X11 connection. Instead we should abort if we cannot connect
to the Wayland display. Also the multi-head checks are not needed on
Wayland, etc. etc. As most of that code is in the main function to
simplify it's better to split.
This will also make it easier to diverge more easily in future. The
Wayland variant can introduce more suited command line arguments for
example. This already started by having the --replace option only
available in X11 variant. The Wayland backend is still a window manager,
but doesn't claim the manager selection.
