Summary:
Context behaviour subtly changed in Qt5.14 which has exposed some
questionable things in this KCM.
Auorae::Decoration is a context property of the loaded QML.
QObject::~QObject signals it's own deletion before deleting children.
This means the bindings of loaded QML update in particular
aurorae.qml
DecorationOptions {
id: options
deco: decoration
}
DecorationOptions has a pointer to the previously set decoration which
is now dangling, and we crash.
Rather than adding more guards and smart pointers in DecorationOptions,
this patch deletes the QQmlContext before deleting the context
properties that we expose.
It also moves unreferring the shared qmlcontext we inherit from till
after we've deleted the child context, because it didn't make sense.
Test Plan:
Opened KCM
Closed the KCM
didn't crash

Summary:
Qt's metaobject is rather sensitive with scope resolution.
Foo::Bar and Bar don't always match to a Qt metaobject, even if they
refer to the same thing to a compiler. Here we register
X11Compositor::SuspendReason but Q_ARG uses SuspendReason and they don't
match. This leads to a runtime failure where the method isn't invoked.
Rather than fixing metaobject usage, port the whole thing to lambdas
which does better compile time checking and is generally nicer to read.

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).
Test Plan: Compiles.

Summary:
In some environemnts it is possible that udev detection of primary GPU
fails and it picks the first available card (normally card0). But it is
not desired, and it would be required to use different card (card1).
Introduce environment variable, which when used, will make it possible
to use different card node then one selected by udev.

Summary:
This patch further refines output management.
We go now through AbstractWaylandOutput virtual functions to enable and
disable outputs.
Dpms changes and enablement switches use separate code paths at start in the
Drm backend code since they are similar but not the directly same. Common code
is shared though, functions are renamed accordingly.
Asserts have been put in place to better understand and check the control
flow. A seemingly unnecessary call to DrmOutput::pageFlipped on reactivation
after Vt switch has been removed to allow for that.
In future patches we need to look additionally at the legacy mode switching
code path which was and is still not working and better handling of the
current monitor Dpms state. For example a monitor being switched off is not
properly acted on and the workspace still expanded.
Test Plan:
With one and two monitors:
* Dpms off/on
* Vt switches
* Screen disable/enable

Make it more explicit what the relation is between Wayland and XDG objects
existing and enablement:
The ouput is enabled if and only if Wayland and XDG output objects exist.

Summary:
This lifts the enablement code for outputs from the DRM backend to Platform
allowing other Wayland backends in the future to use this interface as well.
To do that we also create some helper functions on Platform level and have to
spill some KWayland classes into AbstractOutput what motivates a further split
of Platform into a Wayland child class like for AbstractOutput.
Test Plan: Disabled and enabled an output in DRM session.

Since we now use in the backends the OutputDeviceInterface for output data
all access must be complete before the Wayland server goes down. For that

Qt's object system leading to crashes on double free.

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.
