6cfee149ea Move AbstractWaylandOutput::geometryChanged() to AbstractOutput
On X11, this signal is never emitted because outputs get destroyed when
the output layout changes.

1fb9f6f13a Switch to SPDX license markers
The main advantage of SPDX license identifiers over the traditional
license headers is that it's more difficult to overlook inappropriate
licenses for kwin, for example GPL 3. We also don't have to copy a
lot of boilerplate text.

In order to create this change, I ran licensedigger -r -c from the
toplevel source directory.

a13ecf8d0e [wayland] Add new XdgOutput properties
Summary:
AbstractOutput::name() behaviour is changed so that it matches the X11
behaviour, showing an identifier like "HDMI-0".

XdgOutput.name is set to this name.

XdgOutput.description is currently set to the manufacturer name and
model, but it's not exposed to Qt so we probably don't care too much.

This should fix plasmashell changing applets when switching between X11
and wayland.

Test Plan:
Relevant unit test
I still need to run it on my laptop.

80d3f148e0 [wayland] Simplify output handling
Summary:
Instead of changing lifespan of kwayland objects we can just call
create() and delete() on it which affects the lifespan of the underlying
resource, but not the kwayland wrapper.

This gets rid of some duplicate syncing.

Test Plan:
Ran WAYLAND_DEBUG=1
plugged in and removed a monitor
output showed wl_output and xdg_output being handled correctly

e827d0a8ee Use Transform enum internally
Summary:
Instead of using Qt::ScreenOrientation use an enum class that is directly

b7dbe0e88a Set orientation from DRM on fallback
Summary:
In case of a failed atomic commit the previous mode should be fallen back to.
For orientation provide again a setter that DRM backend can use to set the
transform back to the last working one.

6bfa931f2b Associate output transforms and orientations
Summary:
We use internally Qt:ScreenOrientation for representing output transforms.

This is not ideal since the values do not map directly to Wayland transform
values, but we can make it work by using OR combinations of
Qt:ScreenOrientations.

Do this for now and see if we should not better introduce an internal enum
mapped directly.

Additionally the OR combinations need to be handled in the drm backend at
various places accordingly as well (see TODOs).

Test Plan: Compiles

523967b3ac Set transform in AbstractWaylandOutput
Summary:
Move the Wayland output device and output transform calls from DRM backend
to AbstractWaylandOutput. This leaves still some loose ends that need to be
tied up later. On failed commit we want to fall back to last working state
and orientation getter in general needs some more refactoring.

Test Plan: Compiles.

df3c1de848 [platforms/drm] Rework enablement and dpms switching
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

b3e7664d2c Replace Wayland/XDG outputs checks with enablement checks
Summary:
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.

We can simplify the code by replacing checks on the outputs with checking
the current enablement value.

Test Plan: Wayland nested and virtual backends.

f7ff62e2e2 Lift output enablement into Platform
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.

Summary:
The Wayland and XDG output interfaces are created or destroyed when the
output is en- or disabled. This follows a clear path of dependencies and
we should not check if this is indeed the case but instead assert on it.

684b4b635e Use more traditional doxygen style
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.

8af2fa73dc Run clang-tidy with modernize-use-override check
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.

1a11abc821 [platforms/x11/standalone] Port to AbstractOutput
Summary:
Represent outputs in the X11 session via AbstractOutput. For that we
move all Wayland specific parts of AbstractOutput into a new subclass
AbstractWaylandOutput and let the outputs of our Wayland backends inherit
from there.

This should allow us to get rid of the Screens class later on.

Test Plan: Manually in X session.
