Summary:
Currently, the Night Color manager supports three operation modes:
* Automatic: in this mode, screen color temperature is computed based on
the current position of the Sun. In order to calculate sunrise & sunset
times, the manager needs coordinates of the user, which are provided by
Plasma;
* Location: this mode is very similar to the Automatic, except one minor
detail: user needs to provide his/her/their location. This mode can be
very useful if coordinates provided by Plasma are incorrect;
* Timings: unfortunately we can't compute timings of the Sun for people
living near Earth poles. This mode allows the user to specify timings of
sunrise and sunset as well the transition time.
This change introduces another mode, called Constant. With this mode the
screen color temperature is constant throughout the day. The new mode
can be useful for people wishing constant screen color temperature or
just for people living near Earth's North or South poles.

Summary:
The new shortcut can be useful if a user wants to quickly disable the
Night Color manager for a brief moment.

Summary:
The color correction manager doesn't make any specific assumptions about
underlying platform, e.g. whether it's x11, etc. The platform just
has to be capable of setting gamma ramps. Given that, there are no any
significant technical blockers for making this feature work on x.

Summary:
We have a mix of different doxygen comment styles, e.g.
/*!
Foo bar.
*/
/**
* Foo bar.
*/
/** Foo bar.
*/
/**
* Foo bar.
*/
/**
* Foo bar.
**/
To make the code more consistent, this change updates the style of all
doxygen comments to the last one.
Test Plan: Compiles.

Summary:
GammaRamp deletes an array in the destructor thus we have to either
declare our own copy constructor and copy assignment operator or
delete them both.
GammaRamp looks more like an identity rather than a value so both copy
constructor and copy assignment operator were deleted.
Test Plan: Compiles.

Summary:
With the new Output class we can set the gamma directly here. This is also
a stepping stone to adjust individual output gamma adjustment later on.
This means any future backend, which aims to support the color correction
frontend needs to use the Output class.
Test Plan: Night Color test still passes.

Summary:
Current color temperature must be applied immediately to hot pluged outputs.
BUG: 391623
Test Plan:
Manually. I'm working on auto tests with the new virtual output classes, but
since 5.12.4 will land before I can finish this work, I have to get this fix
in without them.

KConfigSkeleton does not check arbitrary enum values on being
correct. So we do it explicity in our code.

With Wayland KWin needs to provide certain services, which were provided
before that by the Xserver. One of these is gamma correction, which includes
the - by many people beloved - functionality to reduce the blue light at
nighttime. This patch provides the KWin part of that. It is self contained,
but in the end will work in tandem with a lib in Plasma Workspace and a KCM
in Plasma Desktop, which can be used to configure Night Color.
* Three modi:
** Automatic: The location and sun timings are determined automatically
(location data updates will be provided by the workspace)
** Location: The sun timings are determined by fixed location data
** Timings: The sun timings are set manually by the user
* Color temperature value changes are smoothly applied:
** Configuration changes, which lead to other current values are changed
in a quick way over a few seconds
** Changes on sunrise and sunset are applied slowly over the course of few
minutes till several hours depending on the configuration
* The current color value is set immediately at startup or after suspend
phases and VT switches. There is no flickering.
* All configuration is done via a DBus interface, changed values are tested
on correctness and applied atomically
* Self contained mechanism, speaks directly to the hardware by setting the
gamma ramps on the CRTC
* Currently working on DRM backend, extensible to other platform backends in
the future
* The code is written in a way to make the classes later easily extendable to
also provide normal color correction, as it's currently done by KGamma on X
Test Plan:
Manually with the workspace parts and added integration tests in KWin using
the virtual backend.
