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.

b22c362bd5 [platforms/virtual] Let VirtualOutput inherit Output
Summary:
Let VirtualOutput be a child class of the new generic class Output.
This allows code sharing and a very similar behavior of the Virtual backend
in comparision to the Drm backend.

Test Plan:
Autotests succesful with two exceptions: The decoration input test fails on
testDoubleTap, row topLeft. This is to be expected because now the
ScreenEdgeInputFilter captures the event at position (0,0) before the
DecorationEventFilter can capture it. The autotest was adapted to take this
special case into account.

Also the lockscreen test fails, because the virtual output is currently missing
the physical size yet.

fe63e21f80 Introduce generic Output class
Summary:
In order to separate high-level properties of individual outputs from
hardware-specific ones and access these, introduce a new generic class Output.

Also make the DrmOutput class directly a child class of this generic class.

The long-term goal is to get rid of the Screens global object on Wayland and
instead directly work with Output objects on compositing level.

This should enable us long-term to do direct scanout to hardware planes, what
I predict needs this generic output representation at one point.

Test Plan: Manually.

1136386d9f [platforms/virtual] Store virtual outputs per reference
Summary:
Since VirtualOutput is a QObject, store it per reference and not per value.

Also fix some compilation warnings.

Test Plan: Before and after 92% tests passed.

8136c2722b [platforms/virtual] Add virtual output class
Summary:
This matches the DRM backend more closely and allows mid-test removal and
addition of virtual outputs with different properties in the future.

Test Plan: Before and after 93% tests passed.

44e37aacdf Set initial count of screens before calling Screens::init
Screens::init sets up a Qt::QueuedConnection connect from countChanged
to changed. This means that when first setting up the connection a
changed signal will be delivered in the next event cycle. This can mess
with other code. E.g. WaylandServer recreating outputs which can make
Xwayland crash or KWin internally crash.

To solve this problem we just need to make sure to set the output count
to the initial value before performing the init.

d0c488f4a2 Announce output changes to Wayland for platforms not handling outputs
Summary:
Most platforms like the nested and virtual do not handle the outputs
themselves and WaylandServer announces the Outputs to Wayland.

So far this was static: at startup it got announced once to Wayland
and any changes were not catched.

This change makes WaylandServer listen to changes to the Screens and
sync them to Wayland.

Unfortunately KWin's internal Screen information is not sufficient to
properly synchronize this to Wayland and also Wayland by not supporting
adding/removing modes does not help.

Thus the solution implemented here is to add new outputs reflecting the
changes and then removing the old ones. This creates situations with more
outputs being present than actually there, but prevents that there are
no outputs at all.

Test Plan: Auto test added which verifies this for the virtual platform

d0a6aa0836 [platforms/virtual] Support setting random screen geometries
A signal is added to the VirtualBackend to change all screen geometries.
This can be used from auto tests to change the screens. But it's not yet
correctly reflected in other areas. E.g. not forwarded to Wayland Output,
etc.

2bff90976e Move backends/ to plugins/platforms/
Summary:
Source code reorganization:
The base class AbstractBackend got renamed to Platform, thus the
"backends" are "platforms" now. As they are plugins they should go
together with other KWin plugins which are nowadays in the folder
plugins.

So new location is plugins/platforms/
