Cancelling the primary selection breaks text selection in applications
such as gedit. In those apps, you can't select text neither with your
mouse nor keyboard.
BUG: 461498
As explained in [1], WL_SURFACE_ID is racy because wayland aggressively
reuses object ids. The xwayland-shell-v1 protocol intends to fix that by
two things:
* associating a serial number with each X11 window. This is to avoid
potential XID reuse
* referring to the wayland surface by the wl_surface rather than
specifying an object id
Unfortunately, we will have to maintain both legacy WL_SURFACE_ID and
WL_SURFACE_SERIAL for quiet some time until most instances of Xwayland
support the xwayland-shell-v1 protocol [2].

With the pull approach, the XdgOutputV1Interface class doesn't have to
be exposed in the public api and can be made private to simplify the
implementation of the xdg-output-v1 protocol.
Things such as Output, InputDevice and so on are made to be
multi-purpose. In order to make this separation more clear, this change
moves that code in the core directory. Some things still link to the
abstraction level above (kwin), they can be tackled in future refactors.
Ideally code in core/ should depend either on other code in core/ or
system libs.
Requires clients to have the
X-KDE-Wayland-Interfaces=kde_lockscreenallowed_v1 set in their desktop
file, then they will be able to use the kde_lockscreenallowed_v1
protocol to raise any surface above the lockscreen.
The protocol has only 1 method, raise_surface to do exactly that.

Since both output-management-v2 protocol implementation and the rest of
kwin live in the same place and the fact that kde-output-management-v2
is very plasma specific, we can move Platform::requestOutputsChange() to
the implementation of kde-output-management-v2 protocol, it simplifies
the code a bit and improve code encapsulation.
In order to further simplify kde-output-management-v2 protocol, this
change alters the behavior of the protocol so an output configuration
can be applied only once, which is a very reasonable behavior.
At the moment, a platform should provide two output lists - one that
lists all available outputs, and the other one that contains only
enabled outputs. In general, this amounts to some boilerplate code and
forces backends to be implemented in some certain way, which sometimes
is inconvenient, e.g. if an output is disabled or enabled, it will be
simpler if we only change Output::isEnabled(), otherwise we need to
start accounting for corner cases such as the order in which
Output::isEnabled() and Platform::enabledOutputs() are changed, etc.
This change adjusts the window management abstractions in kwin for the
drm backend providing more than just "desktop" outputs.
Besides that, it has other potential benefits - for example, the
Workspace could start managing allocation of the placeholder output by
itself, thus leading to some simplifications in the drm backend. Another
is that it lets us move wayland code from the drm backend.
The IdleDetector is an idle detection helper. Its purpose is to reduce
code duplication in our private KIdleTime plugin and the idle wayland
protocol, and make user activity simulation less error prone.
Anything in xcb_ structs are always in X local, all member variables
aside from buffers are in kwin local space.
This patch ignores a few paths that are not relevant on wayland.
If a window is destroyed before the frame is presented, the window
pointer will be dangling.
In order to make kwin handle that case correctly, the window is captured
using a QPointer.
This makes KWin switch to in-tree copy of KWaylandServer codebase.
KWaylandServer namespace has been left as is. It will be addressed later
by renaming classes in order to fit in the KWin namespace.
AbstractOutput is not so Abstract and it's common to avoid the word
"Abstract" in class names as it doesn't contribute any new information.
It also significantly reduces the line width in some places.
