After paint in case we have swap events the buffer swap should be pending.
This is not always the case with the X11 standalone plugin what needs to be
investigated some more. This is for now a quick fix to make sessions work
again without failing on the assert.
Summary:
When the compositor is stopped there might still be a buffer swap ongoing, in
particular when a client blocks compositing on X11.
Depending on the backend the next buffer swap event might be handled in
bufferSwapComplete (Wayland) or not be handled (X11 GLX, since a new
GLX window will be created while the swap event is sent for the old one).
With this patch the buffer swap state is reset on stop such that on later
start no outdated data might create errors and instead a new repaint can be
triggered with updated data.
BUG: 415262
Test Plan: Manually on X11 and Wayland.

The semantics of a window taking focus on user interaction apply to more roles. See D25851.
Given it is used by KWindowSystem::forceActivateWindow in kwayland-integration,
it makes sense to pass focus to the window once it gets this property set.

Summary:
I could never reproduce the crash, but we know from gdb that it's from
the decorationSettings object
We are setting the same QObject instance as a context property in
multiple contexts at once. This is already slightly odd especially from the POV of
Qt's internal property cache.
Given we want one object to be exposed to all contexts, we can expose it
to the parent context only once and achieve the same result in a simpler
way.

Verified opening and closing system settings still worked for me.

Unfortunately, this patch causes fall apart effect to override sliding

Summary:
The buffer shape is in buffer-local coordinates and must be mapped to
window coordinates. After that, we are free to map it to the global screen

Summary:
If the XRender scene has cross-faded a window, then, eventually, KWin/X11 will
crash in the destructor of the XRenderPictureData class during tear down with
the following message in the terminal
```
ASSERT: "qApp" in file /home/vlad/Workspace/KDE/src/kde/workspace/kwin/libkwineffects/kwinxrenderutils.cpp, line 163
```
The crash happens because X11StandalonePlatform attempts to clean up XRender
resources, including XRenderUtils::s_blendPicture, after the application object
has been destroyed.
In order to fix the crash, we have to destroy the platform object before the
destructor of QCoreApplication is executed.
Test Plan:
- Enable maximize effect
- Maximize a window
- Replace the current instance of KWin/X11 with another one
Without this patch, KWin/X11 crashes after the third step.

Summary:
Activate intel swap events by default if available. They were hidden behind an
environmental variable because of some critical release blocking issue years
ago.
Manual testing indicates that there are no issues anymore with this extension.
Since it allows us to use swap events with MESA drivers for optimized repaints
enable swap events by default again.
For now leave a modified environment variable to switch back to using no swap
events easily.

When initializing a property we loop through the drmModeObjectProperties
object and search for the property by its name.
Once found we create the Property object and there should be not another one
with the same name afterwards. In any case we would leak memory. Therefore just
directly return once the property was found.
This gives us the added benefit that we can put out a warning in case the
property was not found in the loop, what should not happen with the properties
we use.
This is just a code cosmetic change to have the same values internally like the
kernel for the type enum. In the logic there should not be a difference since
the enum values are mapped at runtime.
Summary:
This cleans up some of the code, moves and deletes superfluous functions,
improves in-code docs and runtime warnings.
Test Plan: On vt.

Summary:
According to Gl 3.2 (page 501) and 4.5 (page 204) specs the initial state of
the default framebuffer is already BACK. Therefore we do not need to set it
explicitly.
When we draw in the future to alternative framebuffers which do not have back
buffers this call is fatal.
Test Plan: No tearing on Wayland, tearing as before on X11.

This reverts commit 754b72d155.
In order to make the fix work, we need to redirect the client window
instead of the frame window. However, we cannot to do that because
Xwayland expects the toplevel window(in our case, the frame window)
to be redirected.
Another solution to the texture bleeding issue must be found.
