Currently, if a color scheme lacks the WM group, DecorationPalette
doesn't load it so we can fallback to kdeglobals color scheme. If
kdeglobals doesn't have WM group we get black decorations.
This change will always load the kdeglobals color scheme even if it
is missing WM group.

This is now crucial, because while before
(the minimized) windows were conditionally
shown, but are now always behind the desktop.
Also, it makes the tabbox more consistent.

This is an alternative approach suggested by the
NETWM spec.
The advantage is, that windows are not minimized
at all what apparently lead to some confusion
about the nature of the mode (which was abused
to tidy up) and a secret config key to allow for
that unrelated behavior.
Instead the ShowDesktopIsMinimizeAll key is removed
and replaced by a dedicated script + shortcut.
Bonus: less code to remember "minimized" windows =)
Getting the cursor image from the cursor theme is unfortunately not
straight forward. We have three different libraries and all have
drawbacks:
* XCursor - we just kicked it out
* xcb-util/cursor - only provides xcb_cursor_t, so a dependency on X
* wayland-cursor - only a client side API
The picked solution is using wayland-cursor. It provides the cursor in a
wl_buffer. Unfortunately the client side API does not easily allow to
a) read it back
b) init without a wl_shm_pool
Thus we need to work this around:
* create an internal connection
* get a ShmPool on it
* init WaylandCursorTheme with this ShmPool
* get the cursor wl_buffer from the theme
* trigger a roundtrip
* get the corresponding BufferInterface for the buffer
* set the content as the software cursor
At least the framebuffer backend does not have support for an overlay
cursor. Thus the cursor needs to be rendered by the scene. This change
allows a backend to set that it needs a software cursor which triggers
tracking in the AbstractBackend. A repaint for the old cursor region is
triggered whenever the cursor pos changes.
So far only the QPainter/framebuffer scene is adjusted to render the
software cursor. This is done after rendering a frame with the up to
date cursor position.
There is one problem, though: the KWin internal cursors don't work
as we need to get it from the theme. Using wayland-cursor doesn't help
as it gives us a (client) wl_buffer* and we cannot read the memory back.
A new Singleton VirtualTerminal is added. It interacts with Logind to
get the VTNr to take over. To get the signal to release and acquire the
VT we use a signalfd with a QSocketNotifier to monitor for signals. The
used signals must be blocked for all threads prior to startup otherwise
they are delivered to secondary threads causing issues.
When our session gets inactive libinput loses all devices, thus our
Seat would not have neither keyboard, pointer nor touch. To not confuse
all connected clients we block updates while libinput is suspended. After
resume we check whether something actually changed and emit the
corresponding signals to ensure everything is up to date.
The AbstractBackend provides a virtual method to create the Screens.
A concrete backend can implement this method to create the backend
specific Screens instance.
This removes the casting logic from Screens::create.
Adapt to API changes introduced by b62e8888cd39301e00ad98dfe791fa66676408fb.
It adds DecoratedClient::color(group, role) for getting colors that are
not included in QPalette. Breeze used to read these colors from
kdeglobals, breaking per window color schemes. KWin now handles reading
these colors along with QPalette loading with DecorationPalette.

This adds "Quick Tile Window to the Top" and "Quick Title Window to the Bottom" shortcuts. These are
useful for those using displays that are in portrait orientation.

We handle device added/remove to monitor whether we have keyboard,
pointer and touch devices and emit signals. Those are used to update
the SeatInferface from InputRedirection.
