Libinput is an optional dependency for getting low level input events.
As opening the input devices requires root privs this is rather
pointless in the current state. But there is a small added test app which
can be executed with root privs to demonstrate the functionality. To
properly get input events we need a wrapper like it's used in weston.
So far the following is setup:
* opening devices found by udev
* forwarding keyboard events to InputRedirection
* forwarding pointer button events to InputRedirection
* forwarding pointer axis events to InputRedirection
* signals emitted for pointer motion events
Pointer motion events need some further work as they are provided
as delta events. We need to track that and map them properly.
Also missing are touch events due to me not having a touch screen.
It should be fairly simple to setup the touch events, though.
Also hotplugging of devices is not yet implemented.
This servers two purposes.
1. it makes KWin/5 co-installable with KWin/4 as now binary and
all libraries etc. are renamed or installed to a different
location.
2. In future we need a dedicated X11 and Wayland main function
anyway. Thus it makes most sense to rename to kwin_x11 directly
instead of first renaming to kwin5. The reason why we need to
have dedicated main functions is that kwin needs to check early
whether X11 is working or Wayland is working. Right now the first
thing kwin does is trying to connect to the XServer. This happens
before the QApplication is constructed and before command line
args are processed. On Wayland we won't want to test whether we
can connect to the XServer. As it's too early to check whether we
are starting kwin for X11 or Wayland the most convenient way is to
have dedicated binaries - thus a rename is needed. Just renaming
kwin for wayland is also not a good idea as in future the "main"
kwin will be for wayland not for X11. Another case for the dedicated
binaries is the Application class, which right now first tries to
claim the X11 Window Manager Selection. Again on Wayland even with
XWayland we won't need that. KWin will be the window manager for
XWayland if KWin is the Wayland compositor. There is no need to even
try to support anything else. Most likely it will even be KWin to
start the XWayland server, so we can be sure that there is no other
WM running and thus no need to claim the selection and abort if it
fails.

ICCCM dependency is a beast due to two different existing versions in
different packages. Thus it cannot be a hard dep without causing problems
for our downstreams.
This change ensures that ICCCM is really considered as an optional dep
and that the version we need is found, if not we mark it as non-found.
ICCCM is only used by one test application which can easily be disabled
and some enum values are used in events.cpp. If ICCCM is not found those
are replaced by defines generated in config-kwin.h.

Major new functionality is xkbcommon support. InputRedirection holds an
instance to a small wrapper class which has the xkb context, keymap and
state. The keymap is initialied from the file descriptor we get from the
Wayland backend.
InputRedirection uses this to translate the keycodes into keysymbols and
to QString and to track the modifiers as provided by the
Qt::KeybordModifiers flags.
This provides us enough information for internal usage (e.g. pass through
effects if they have "grabbed" the keyboard).
If KWin doesn't filter out the key events, it passes them on to the
currently active Client respectively an unmanaged on top of the stack.
This needs still some improvement (not each unmanaged should get the
event). The Client/Unmnaged still uses xtest extension to send the key
events to the window. So keylogging is still possible.
Scripting has proved it's point of being useful so it's time to turn it
into a mandatory part of KWin.
Also I start to use features provided by Scripting in more and more
parts of KWin core (e.g. sharing QQmlEngine) which makes it in the
long to complicated to have a build option and ifdefs for it.

This build option is added to make it easier to build just KWin without
kde-workspace. This is a common requirement by developers wanting to
contribute to KWin and only want to build KWin but use everything else
from their normal distribution.
Building KWin standalone is very often difficult due to Oxygen. If the
library has changed it is not possible to build just KWin without also
building the workspace libs and if you do so you run into ABI problems
when trying to start KWin - either the decoration or the style is
crashing due to not matching libraries.
To circumvent this common issue for new developers this build option
is introduced to just exclude the Oxygen window decoration and defaulting
to Plastik.
Of course by default this option is turned ON, so that the Oxygen
decoration gets build. By default there is no change at all.

As discussed on the mailinglist [1] the tiling support is
removed from KWin. The main reasons for this step are:
* it is unmaintained
* it is a mode not used by any of the core KWin team
* original developer said at Akademy 2012 that he is not
interested in picking up the work again
* tiling has quite some bugs, e.g. multi screen not supported
* is conflicting with other concepts in KWin, e.g. activities
There is ongoing work to get tiling supported through a KWin
script, which is a preferred way as it does not influence the
existing C++ code base.

A CMake variable is used to specify the name of the binary.
By default this is "kwin" but building for PA changes the
name to "kwinactive". The variable adjusts all names, e.g.
kwinnvidiahack becomes kwinactivenvidiahack.
The remaining usage of kwinrc in core and libs is replaced
by a cmakedefine for the configuration name and all data
installations are moved to the defined name. Dynamic loading
for scripts & co is adjusted for loading based on defined name.
This change allows the side-by-side installation of both kwin
for desktop and kwin for Plasma Desktop without the known
issues like conflicts in config files or missing build options
if kwin desktop is used for Plasma Active.
Likewise the KCMs are not adjusted as they are not intended to
be used for kwinactive.

A build option is introduced to file CMakeLists.txt. Classes Tiling,
Tile and TilingLayouts are only built if the option is set to ON. #ifdef's
are added to the classes where functions of the excluded classes are called.
It is possible that adding this build option broke the Scripting
component. This is something that should not happen. Unfortunately
by just ifdefing everything scripting related with scripting enabled
we have build errors. These are caused by the fact that the scripting
code includes e.g. client.h through "./../client.h". At one offending
place I changed that to "client.h", but there is also a client.h in
the scripting directory.
The includes and naming of the scripting files clearly have to be fixed!
Since the TabBox functionality is not feasible for any platform KWin is
used on (e.g. tablet PCs), a build option is added to decide, if the
TabBox functionality should be build or not.
