6d0cca5c7f Move all dirty region scene repaint scheduling to Scene
The Compositor contains nothing that can potentially get dirty and need
repainting.

As is, the advantages of this move aren't really noticeable, but it
makes sense with multiple scenes.

Backend parts are far from ideal, they can be improved later on as we
progress with the scene redesign.

bad5752110 platforms/drm: kill the EglStreams backend
The proprietary NVidia driver now supports gbm, which vastly improves the
user experience. For older devices that will not get gbm support dropping
EglStreams will likely not have a big impact as it has several session breaking
issues anyways.

By removing the backend a lot of logic can be simplified, most notably multi-gpu.

02bb276ebf platforms/drm: Move ownership of mode blob to connector mode
The main motivation behind this change is to move management of drm
blobs out of property wrappers in specialized wrappers to simplify state
management with blobs.

Connector mode blobs are created on demand.

as well.

7283c98f27 platforms/drm: disable unused resources on modesets
When we switch CRTCs it can happen that a CRTC would stay enabled yet has
no connectors anymore. In this case the kernel may reject our atomic commit,
which would cause the modeset to fail. To counteract that, properly disable
unused drm objects

a07aae8282 platforms/drm: delay presentation for modesets
Currently KWin is combining modesets with presentation, which causes problems
when multiple monitors are used and crtcs need to be switched around, because
taking away a CRTC from another output causes the driver to disable the
other output. In order to avoid such problems, delay presentation until
all pipelines are ready to present and then do a modeset with a single atomic
commit. To process the resulting page flip events properly this commit also
ports KWin to page_flip_handler2 and changes how the pageFlipped and
notifyFrameFailed signals are processed.

e2a0863843 platforms/drm: more dynamic crtc assignment
Hardware constraints limit the number of crtcs and which connector + crtc
combinations can work together. The current code is searching for working
combinations when a hotplug happens but that's not enough, it also needs
to happen when the user enables or disables outputs and when modesets are
done, and the configuration change needs to be applied with a single atomic
commit.

This commit removes the hard dependency of DrmPipeline on crtcs by moving
the pending state of outputs from the drm objects to DrmPipeline itself,
which ensures that it's independent from the set of drm objects currently
used. It also changes requests from KScreen to be applied truly atomically.

3485eb6200 cmake: Move base render backend classes to libkwin
This allows using base opengl backends in libkwin, which can be useful
later on for the purpose of moving the ownership of render backends from
the Scene class to the Compositor class.

d89501a079 Move platform backends to backends directory
This improves file organization in kwin by putting backends in a single
directory.

It also makes easier to discover kwin's low level components for new
contributors because the plugins directory may come as the last place to
look for. When one hears "plugin", the first thing that comes to mind is
regular plugins, not low level backends.
