Summary:
The ClockSkewNotifier provides a convenient way for monitoring system
clock changes. One of the key ideas was to hide platform details from
users of the class. This allows us to add a QTimer fallback path for
operating systems that don't provide anything to detect system clock
changes.
In long term, I would like to move the new class to Frameworks.

Summary:
Currently, in order to retrieve the current screen color temperature
applied to all screen as well other attributes of night color manager,
one has to call nightColorInfo() periodically. This goes against well
established patterns in d-bus world. It is recommended to expose a
bunch of d-bus properties rather than have a method that returns all
relevant properties stored in a JSON object.
The ugliest thing about this patch is that a lot of code is duplicated
to emit the PropertiesChanged signal. Unfortunately, QtDBus doesn't
take care of this and we are left with only two options - either do
weird things with QMetaObject or manually emit the signal. I have
picked the second option since it's more comprehensible and less magic
is going on, but I have to admit that the chosen approach is ugly.
I hope that "Qt 6 will fix it."

Summary:
Currently Night Color doesn't handle time zones very well. For example,
if the user's time zone is UTC-8, then computed timings of sunrise and
sunset (in UTC) will be a bit gibberish as sunset occurs before sunrise
rather than vice versa.
This change switches relevant parts of Night Color to local time in
order to fix expectations about the order of morning and evening in
updateSunTimings() method as well to simplify the code a bit (dealing
with UTC and local time can be painful sometimes).

Summary:
Because KWin is a very old project, we use three kinds of null pointer
literals: 0, NULL, and nullptr. Since C++11, it's recommended to use
nullptr keyword.
This change converts all usages of 0 and NULL literal to nullptr. Even
though it breaks git history, we need to do it in order to have consistent
code as well to ease code reviews (it's very tempting for some people to
add unrelated changes to their patches, e.g. converting NULL to nullptr).

Summary:
So far we were following a bit unique and rare doxygen comment style:
/**
* Contents of the comment.
**/
Doxygen comments with this style look balanced and neat, but many people
that contribute to KWin don't follow this style. Instead, they prefer
more traditional doxygen comment style, i.e.
/**
* Contents of the comment.
*/
Reviewing such changes has been a bit frustrating for me (so selfish!)
and for other contributors.
This change switches doxygen comment style in KWin to a more traditional
style. The main reason for doing this is to make code review process easier
for new contributors as well us.

Summary:
Currently code base of kwin can be viewed as two pieces. One is very
ancient, and the other one is more modern, which uses new C++ features.
The main problem with the ancient code is that it was written before
C++11 era. So, no override or final keywords, lambdas, etc.
Quite recently, KDE compiler settings were changed to show a warning if
a virtual method has missing override keyword. As you might have already
guessed, this fired back at us because of that ancient code. We had
about 500 new compiler warnings.
A "solution" was proposed to that problem - disable -Wno-suggest-override
and the other similar warning for clang. It's hard to call a solution
because those warnings are disabled not only for the old code, but also
for new. This is not what we want!
The main argument for not actually fixing the problem was that git
history will be screwed as well because of human factor. While good git
history is a very important thing, we should not go crazy about it and
block every change that somehow alters git history. git blame allows to
specify starting revision for a reason.
The other argument (human factor) can be easily solved by using tools
such as clang-tidy. clang-tidy is a clang-based linter for C++. It can
be used for various things, e.g. fixing coding style(e.g. add missing
braces to if statements, readability-braces-around-statements check),
or in our case add missing override keywords.
Test Plan: Compiles.

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.

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.
