QtQuick's OpenGL context an RGBA surface makes Qt way more happy.

Summary:
With this change the Wayland platform plugin uses the XdgShell to
create the window if available. This allows to close the window and
thus quit the nested kwin_wayland properly.

Some error conditions did not have a warning, so all we got is
"Could not initialize rendering context". Which is not helpful to
figure out what is going wrong.
For virtual machines with Cirrus device the drmModeAddFB fails. So
far there was no error message at all, we only saw it failed.
With this change the drmModeAddFB is checked for error and a warning
is shown. Also further debug messages are added for other cases where
things can fail.

Summary:
So far if the framebuffer platform run into an error on initialization
it did not continue and caused the system to freeze. With this change
it properly emits the initFailed signal in all error conditions which
causes kwin_wayland to terminate. This is a much better situation than
just staying in a running, but frozen state.

Summary:
If it's not possible to create a buffer to blank the output, KWin won't
be able to render to the output. In that case the output should not be
added to the list of outputs.
To support this DrmOutput::blank and DrmOutput::init return bool to
indicate whether they succeeded. DrmBackend handles this situation and
doesn't add the output to the list of outputs if init failed.
If after init there are no outputs KWin is in a state where it won't
be functional. Thus the platform emits the initFailed signal to
terminate.

Summary:
If the format of the framebuffer is BGR we cannot create an RGB image
format from it - the rendering is incorrect. Unfortunately QImage does
not support a BGR image format.
To solve this problem we still use an RGB image format but on rendering
the front buffer is rgbSwapped to convert the RGB image to a BGR image.

Summary:
No need to delegate the painting of the software cursor into the backend.
The core has enough information to perform the rendering itself.
This change means less code duplication and all platforms which might use
a software cursor in QPainter compositor gain support for it without any
further adjustments.

Summary:
So far the drm platform did not verify whether creating and mapping a
DrmBuffer for a cursor works. This could result in a crash in the worst
case.
This change verfies whether mapping the two cursor buffers works, if
not software cursor is enabled. The code is adjusted to ensure that
none of the cursor buffers is accessed in case software cursor are
enabled.
Please note that right now the drm platform's rendering does not
support software cursors. Thus currently this change results in no
cursor at all. This will be addressed by following patches.

Summary:
Platform::setSoftWareCursor creates connections to the Cursor in order
to trigger repaints whenever the cursor position changes. The Cursor is
created before Platform::init is called, but after the Platform is
created. Thus the call needs to happen in init, otherwise the cursor
is not rendered correctly.

Summary:
When we get a configuration request, we also need to update the global
position on the DrmOutput, otherwise Wayland will know about the new
position, but KWin internally does not.
In addition we also need to trigger the changed signal on KWin::Screens,
so that internally code can react on the change.
With this change configuring layout of connected screens in KScreen
does work also in KWin.

Summary:
To use eglCreateImageKhr for an X11 pixmap we need an EGLDisplay created
for the same XDisplay as the X11 pixmap. This means if we created an
EGLDisplay for a GBM device, we are not allowed to load a texture from
the X11 pixmap and can result in a crash in the driver.
Similar in the nested X11 setup the EGLDisplay is created for the
rendering window, but the X11 pixmaps are from the Xwayland server KWin
started. They don't belong to the same windowing system.
This change addresses this problem by moving the loading of X11 pixmaps
from AbstractEglTexture to EglTexture of the EglOnX11Backend. Thus for
any usage on a non X11 platform we cannot hit the code path any more.
In addition the nested X11 platform can indicate that it doesn't support
it and thus also doesn't go through the code path.
Test Plan: Tested standalone and nested X11 platform

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.
Summary:
When the pointer device gets plugged off the cursor is hidden, when
a pointer device gets plugged in the cursor is shown again.
This allows to easily turn a tablet into a proper system by showing
the cursor only when it makes sense.

Summary:
A new virtual method createOpenGLSafePoint is added to Platform.
This is invoked through the Compositor with a PreInit and a PostInit
argument pre and post creating the SceneOpenGL.
The Platform plugin can implement this and use it for detecting whether
creating the OpenGL compositor on this platform crashed in the past.
Thus it's the base for the openGLIsBroken platform check.
The x11 standalone plugin is the first to implement this functionality
using the previous code which was designed for X11.
This also means that a crash of the OpenGL compositor during init on
Wayland won't result in OpenGL being disabled.

Summary:
So far the OpenGL is unsafe check functionality in Compositor disabled
OpenGL compositing if glx is not available and we are in standalone X11
mode.
This is technically no longer correct for quite some time. Just because
GLX is not available doesn't mean that OpenGL doesn't work. We have an
EGL backend. So let's try to use that if glx is not available.
This change removes the check completely from Compositor. Instead the
standalone x11 plugin checks whether glx is available prior to createing
the glx backend. If not available it falls through to the egl backend.

Summary:
CompositingPrefs is only relevant for X11 standalone. It had some
"hacks" to make it not block Compositing on Wayland. Thus it was in
its current form not really useful.
Now all the functionality is provided through Platform with a default
implementation which is sensible for Wayland platforms.
The X11 standalone platform implements the new methods with the
Wayland checks removed.
In addition all calls to CompositingPrefs now go through the platform
directly and CompositingPrefs is completely dropped.

Summary:
This change reduces the windowing system specific code pathes. Instead
of checking whether we are on X11 or Wayland to decide whether
compositing is required, we just ask the Platform.
The default is true, only x11 standalone allows to not require
compositing.

Removes a diversion between X11 and Wayland. The base class Platform
creates an instance of class Edge with plugin implementations being
able to create a different type.
The X11StandalonePlugin does that and creates a WindowBasedEdge. For
this the implementation of WindowBasedEdge is moved from screenedges
into the plugin.
Unfortunately an ifdef is needed to make the screenedge test still
work as expected. This should be improved in future, e.g. have a good
way to load the platform plugin from the tests.

By moving XRandrScreens the creation of screens gets simplified a lot
as there is no need to have windowing system specific init code. It all
just goes through the platform.
This also marks the point where the first X11 specific code is removed
from kwin_wayland.

The plugin does not much. It's the most basic plugin we can have to
be loaded from kwin_x11.
Unlike the wayland platform plugins it gets installed to:
org.kde.kwin.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/
