When getting the vector, it requires us to check both if it's not empty
but also that it's not null. I haven't seen it but we were not doing
this check.
Just return an empty vector when there's no devices instead.
Let UdevDevice offer the method we need for sorting instead of just half
of it.
Always sort Udev enumerations, since the alternative is to sort it every
time it's called otherwise.
In the few cases where the framebuffer is needed, we'd get problems
because ioctl(KWIN_FB_NO_VSYNC) fails.
This removes the code entirely to just use a timer to refresh.

QPainter::setWindow() doesn't work as we expect if the device pixel
ratio of the paint device is less than 1, for example 0.5 or 0.75.
QPainter only allows the effective device pixel ratios that are greater
than or equal to 1. This restriction probably has to be lifted.
For the time being, this change introduces a helper function that can be
used to determine the scale factor by which QPainter::window() must be
multiplied.

Reducing the oppacity of these windows causes them to appear as phantoms
in the corners of the screen. They look quite odd on top of anything else
in the corners of the screen, such as any Plasma panels.
However making them 100% opaque doesn;t work either, since then they
look interactive, but they're not, and can't be made so due to the
scripting API used here.
So our only real option to remove the weirdness is to make them 100%
transparent, and therefore show the entirety of the desktop with no sign
that the effect is in use.
Instead of deleting all blob properties without a valid
blob check for the blob existing before using it. This is
necessary because some properties are needed even without
currently valid blobs.

While the session is inactive, the drm master permissions are revoked.
Therefore, we cannot perform things such as modesetting, etc. It also
makes no sense to create or destroy DrmOutput objects.

This reverts commit 5a22deda3b.
We still need more work to finish the DrmPipeline. At the moment, there
are a few major issues, e.g. some outputs not turning on, output
transforms not working correctly, a crash when changing dpms mode.
Let's merge this change back once all major issues are fixed and after
more testing.
We'd be relying on AbstractEglDrmBackend on calling cleanup but we'd be
doing it when cleanupSurfaces cannot be reached out anymore, turning it
into a half-baked cleanup.
Instead call cleanup from the leaf class destructors.
