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.

BorderNoSides is what is known from Oxygen as "No Side Borders". The name
should indicate that there is only a border at the bottom. BorderNone is
a mode with no borders at all.
The new enums are added to KDecoration and the KCM so that all decos can
make use of it.
Aurorae is adjusted to support the new sizes for QML themes (it breaks
the old svg based themes) and Plastik makes use of it, by rendering a
one-pixel border around the window, which illustrates that it's still up
to the decoration to decide how to make use of the setting.

If the decoration listing gets initialized directly in the ctor as it
used to be, there is the chance of the list being not rendered in case
that there are multiple KCMs in one container and one has to switch to
the decoration KCM. This is the case for e.g. opening the KWin
configuration through the Alt+F3 menu. But that never happened when
going through Systemsettings as there (at least with English) it is
listed as the first module.

Add an option to kcmcompositing in the 'Advanced' tab, to enable or
disable color correction. It is specified that it's experimental and it
needs Kolor Manager.
Before painting for a particular screen, ColorCorrection::setupForOutput
should be called.
A screen property is added for WindowPaintData.
In kwinglutils, The fragment shaders are intercepted before being
compiled and they get a couple of lines of code inserted in order to do
the color correction. This happens only when color correction is enabled, of
course.
For D-Bus communication with KolorServer, everything is async.
The implementation basically manages a set of color lookup tables for
different outputs and for different window regions. These are taken via
D-Bus. Each lookup table has around 700 KB.
This commit reintroduces the changes from the former merge with the
"color2" branch. In this form, it can be easily reverted.

This merge is incomplete and it does not include the review number of
the associated review request. It should have been pushed as a single

Plastik has been removed and the new Aurorae has the same requirement as
Oxygen. This fallback was anyway useless given that KWin nowadays uses
raster paint engine by default and hardly anything would work with such a
small QPixmap::defaultDepth().

Functionality had already been present for quite some time and now that
the category on kde-look exists, we can just show the button.
