This is a temporary workaround for bug 349992 which causes freezes
during startup as kwin and kamd dead lock each other on DBus.
To workaround we don't call Activities::create and check in every
usage of Activities::self() whether the pointer is valid.
As a result kwin_wayland now starts pretty fast.

kdeinit_executable doesn't make sense in the case of kwin_wayland as
start_kdeinit_wrapper will be executed after kwin_wayland thus the
framework doesn't work.
The KGlobalAccelD which gets created by KWin needs a plugin for the
platform specific parts. This change introduces such a plugin. It's
linked against kwin so that it can integrate with the core.
On enable the plugin registers itself in the InputRedirection and
GlobalShortcutsManager checks the plugin whether a shortcut got
triggered.
As the loading of the plugin must happen after InputRedirection is
fully created a dedicated init method is added to InputRedirection.

Internally QX11Info::display() calls into QPA native interface and
tries to resolve the nativeResourceForIntegration for "display".
Unfortunately this key also exists in other QPA plugins, e.g. in
QtWayland.
Calling without a check on platform results on wayland qpa in
wl_display* being casted into Display*.

During cleanup the KWayland::OutputInterface is already destroyed before
we hit the cleanup code of DrmOutput. Thus guard with a QPointer to not
delete twice.
If none of the backend specific command line options are passed, we
try to autmatically determine the proper plugin.
1. if DISPLAY is set -> x11 backend
2. if WAYLAND_DISPLAY is set -> wayland backend
3. if compiled with libhybris and ANDROID_ROOT is set -> hwcomposer backend
4. if compiled with DRM -> drm backend
5. if nothing selected yet, fallback to fbdev
If an env variable is set outside of KWin (e.g. QT_QPA_PLATFORM) we
want KWin to pass the original env variable to the started process and
not pass none instead because it's one of KWin's special changed
variables.
Thus we take the environment before we adjust it and pass that to the
started processes with our own DISPLAY and WAYLAND_DISPLAY added.
Ensures that the PlasmaWindow gets destroyed together with the window.
Note: when a ShellClient gets unmapped the PlasmaWindow does not yet
get destroyed. It should probably get destroyed and recreated on next
mapping.
Logic similar to Client::takeFocus: if window is keep above or on
screen display do not break. Also if window belongs to the same
ClientConnection as a desktop window don't break.
If the icon doesn't have a name, we pass the generic xorg icon. Most
likely our xwayland clients won't have a theme name, so giving them
the xorg icon seems a good enough work around. If we would want to
pass the real icon for xwayland clients we would need a way to
serialize them which seems like quite some needless overhead for legacy
applications. Can be considered for the future nevertheless.
Prime target is to preserve the in-screen
condition of client AND window.i[1]
Atm. when the client is fully in sight
(but the window is not) - regardless of snapping
or screen change - a workspace update (screen change,
resolution change, adding/removing a strutting panel)
would allow the client to partiall escape screen bounds.
This is changed so that if the client is fully in sight,
it's kept fully in sight (but not the decoration)
If the entire window was fully in sight, it's also kept
(as is right now)
The code handles inner screen edges (if the client was in sight,
the entire window will be if we'd bleed to the other screen)
[1] I'd say that handling the client is more relevant,
but foresee more complaints if the window wasn't handled anymore ;-)
During that, i stumbled across some other issues.
- when a window centered on one screen is moved to a screen smaller
than the window, the window is shrinked to the dimensions of that
screen and now randomly touches eg. left AND right edge. When
moved back, the right and bottom edge were preferred
(to the window was "moved" into the lower right corner).
It's now kept centered.
- geom_restore was saved before keeping the window in the new
screen area (causing accidental drops on screen changes)

Toplevel provides the input shape forwarded from SurfaceInterface. The
shape is evaluated in InputRedirection when finding the Toplevel at a
given position.
With Xwayland clients it can happen that the window gets destroyed
before it ever got a surface (Qt 5's file open dialog being an example).
This change delays such clients till it got the surface, removing not
needed roundtrips and possible problems.
So far this only allows to trigger show desktop functionality and exports
the state.
In future this should be restricted to just one dedicated desktop shell
process.
We used to change it only on keypresses. This resulted in the strange
situation that e.g. the input method virtual keyboard doesn't show up
until one presses a real key, because e.g. maliit only activates the
keyboard if there is an active focus object in the Qt application.
