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.

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.

33a4cf4050 [drm] Implement changing of modes
Summary:
This change hooks up the bits for changing the mode when a request to
change mode from kscreen is received. This includes:
 * setting new mode in DrmOutput
 * creating new buffers in SceneQPainter backend
 * creating new GbmSurface in SceneOpenGL backend

Room for improvement:
 * detect whether the new mode works and go back to old one if it fails

Test Plan:
Started both a QPainter/OpenGL session. Used kcmshell5 kscreen
to modify the resolution. Saw that it got applied, maximized a window to
verify it's correct. Changed back to original resolution. Verified it looked
good by maximizing a window.

Test Plan:
For the first time, actually plugged in my high DPI laptop.
Tested both 1x and 2x windows on 2 real displays one high DPI, one normal

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/
