1041ef8275 platforms/drm: introduce virtual outputs
When the last output gets disconnected, create a virtual output as a
placeholder until we have access to a physical output again. While
this placecholder never gets rendered to, with virtual outputs in
general that is possible (with gbm and qpainter atm) and can be done
for future use cases like wireless displays.

e087b2ce2f platforms/drm: Add buffer age support in qpainter backend
Currently, the entire screen will be repainted when using the qpainter
render backend. With this change, kwin will repaint only the dirty parts
on the screen.

2fe102768a Remove QPainterBackend::needsFullRepaint()
A better alternative is to return the damage region in the beginFrame()
function. This way, the render backend can force full screen repaints or
indicate what parts of the buffer needs to be repainted (for buffer age)

4abbb6f0d6 Make OpenGLBackend and QPainterBackend QObjects
Almost all their subclasses are QObjects. This simplifies the class
hierarchy by making OpenGLBackend and QPainterBackend qobjects.

d543c0dff6 Remove unused mask param in QPainterBackend::endFrame()
It is unused and it is not a good idea to pass Scene's mask to the
render backend as it results in higher coupling between Platform and
Scene.

7de0f1f2ad platforms/drm: CPU copy for multi-gpu
Not all GPUs can scan out linear buffers, so if import with a dmabuf
fails manually copy the data into a non-linear gbm buffer instead.

93e0265e4e Move source code to src/ directory
Once in a while, we receive complaints from other fellow KDE developers
about the file organization of kwin. This change addresses some of those
complaints by moving all of source code in a separate directory, src/,
thus making the project structure more traditional. Things such as tests
are kept in their own toplevel directories.

This change may wreak havoc on merge requests that add new files to kwin,
but if a patch modifies an already existing file, git should be smart
enough to figure out that the file has been relocated.

We may potentially split the src/ directory further to make navigating
the source code easier, but hopefully this is good enough already.
