Summary:
In long term, we want to split XdgShellClient into several classes. One
class for xdg-toplevel clients, and the other one for xdg-popup clients.
xdg-popup clients are much simpler than xdg-toplevel clients, they can't
be maximized or shown in full screen mode, they can't be interactively
moved on the screen, and so on. In the end, we will have to plumb many
pure virtual methods, which looks a bit ugly.
This change makes support for full screen mode in AbstractClient optional
so we don't have to add those no-op methods and keep code more or less
"clean."
Test Plan: Compiles.

Summary:
Nothing special about this patch except of the removal of code that forces
_NET_WM_STATE_BELOW and _NET_WM_STATE_ABOVE. If the client window is
compliant with the EWMH spec, then _NET_WM_STATE_BELOW and _NET_WM_STATE_ABOVE
will be in sync with keepBelow() and keepAbove(), respectively.

Summary:
Currently we have two signals that are emitted when the Toplevel's geometry
changes - geometryShapeChanged() and geometryChanged(). The former signal
is used primarily to invalidate cached window quads and the latter is
sort of emitted when the frame geometry changes. But it's not that easy. We
have a bunch of connects that link those signals together...
The worst part about all of this is that the window quads cache gets
invalidated every time a geometry update occurs, for example when user
moves a window around on the screen.
This change introduces a new signal and deprecates the existing geometryChanged
signal. frameGeometryChanged is similar to geometryChanged except that it is
emitted when an _actual_ geometry change has occurred.
We do still emit geometryShapeChanged signal. However, in long term, we
need to get rid of this signal or come up with something that makes sense
and doesn't require us to waste computational resources.

Summary:
If the frame geometry is changed in any away, for example if the client
has been moved, resized, or both, setFrameGeometry() will schedule a layer
repaint for the visible geometry before and after the update.
When there is a resize effect, we only send requests to the client window
to render contents at the new size. setFrameGeometry() is not called and
therefore no layer repaints are scheduled.
Only the resize effect knows what parts of the window or the screen must
be repainted and thus it must be responsible for scheduling repaints.
A full repaint in AbstractClient::performMoveResize() is scheduled mostly
for historical reasons.

Summary:
Qt has its own thing where a type might also have corresponding list
alias, e.g. QObject and QObjectList, QWidget and QWidgetList. I don't
know why Qt does that, maybe for some historical reasons, but what
matters is that we copy this pattern here in KWin. While this pattern
might be useful with some long list types, for example
QList<QWeakPointer<TabBoxClient>> TabBoxClientList
in general, it causes more harm than good. For example, we've got two
new client types, do we need corresponding list typedefs for them? If
no, why do we have ClientList and so on?
Another problem with these typedefs is that you need to include utils.h
header in order to use them. A better way to handle such things is to
just forward declare a client class (if that's possible) and use it
directly with QList or QVector. This way translation units don't get
"bloated" with utils.h stuff for no apparent reason.
So, in order to make code more consistent and easier to follow, this
change drops some of our custom typedefs. Namely ConstClientList,
ClientList, DeletedList, UnmanagedList, ToplevelList, and GroupList.

Summary:
KDE is known for having a strong view on the client-side decorations vs
server-side decorations issue. The main argument raised against CSD is
that desktop will look less consistent when clients start drawing window
decorations by themselves, which is somewhat true. It all ties to how
well each toolkit is integrated with the desktop environment.
KDE doesn't control the desktop market on Linux. Another big "player"
is GNOME. Both KDE and GNOME have very polarized views on in which
direction desktop should move forward. The KDE community is pushing more
toward server-side decorations while the GNOME community is pushing
more toward client-side decorations. Both communities have developed
great applications and it's not rare to see a GNOME application being
used in KDE Plasma. The only problem is that these different views are
not left behind the curtain and our users pay the price. Resizing GTK
clients in Plasma became practically impossible due to resize borders
having small hit area.
When a client draws its window decoration, it's more likely that it also
draws the drop-shadow around the decoration. The compositor must know
the extents of the shadow so things like snapping and so on work as
expected. And here lies the problem... While the xdg-shell protocol has
a way to specify such things, the NetWM spec doesn't have anything like
that. There's _GTK_FRAME_EXTENTS in the wild, however the problem with
it is that it's a proprietary atom, which is specific only to GTK apps.
Due to that, _GTK_FRAME_EXTENTS wasn't implemented because implementing
anything like that would require major changes in how we think about
geometry.
Recent xdg-shell window geometry patches adjusted geometry abstractions
in kwin to such a degree that it's very easy to add support for client
side decorated clients on X11. We just have to make sure that the
X11Client class provides correct buffer geometry and frame geometry when
the gtk frame extents are set.
Even though the X11 code is feature frozen, I still think it's worth
to have _GTK_FRAME_EXTENTS support in kwin because it will fix the resize
issues. Also, because KWin/Wayland is unfortunately far from becoming
default, it will help us with testing some implementation bits of the
window geometry from xdg-shell.

In order to properly implement xdg_surface.set_window_geometry we need
two kinds of geometry - frame and buffer. The frame geometry specifies
visible bounds of the client on the screen, excluding client-side drop
shadows. The buffer geometry specifies rectangle on the screen that the
attached buffer or x11 pixmap occupies on the screen.
This change renames the geometry property to frameGeometry in order to
reflect the new meaning assigned to it as well to make it easier to
differentiate between frame geometry and buffer geometry in the future.

Summary:
Currently each managed X11 client is represented with an instance of
Client class, however the name of that class is very generic and the
only reason why it's called that way is because historically kwin
was created as an x11 window manager, so "Client" was a sensible choice.
With introduction of wayland support, things had changed and therefore
Client needs to be renamed to X11Client in order to better reflect what
that class stands for.
Renaming of Client to X11Client was agreed upon during the last KWin
sprint.
Test Plan: Compiles, the test suite is still green.

Summary:
So far wayland was used by internal clients to submit raster buffers
and position themselves on the screen. While we didn't have issues with
submitting raster buffers, there were some problems with positioning
task switchers. Mostly, because we had effectively two paths that may
alter geometry.
A better approach to deal with internal clients is to let our QPA use
kwin core api directly. This way we can eliminate unnecessary roundtrips
as well make geometry handling much easier and comprehensible.
The last missing piece is shadows. Both Plasma::Dialog and Breeze widget
style use platform-specific APIs to set and unset shadows. We need to
add shadows API to KWindowSystem. Even though some internal clients lack
drop-shadows at the moment, I don't consider it to be a blocker. We can
add shadows back later on.

Summary:
There are rules that have to be applied only once, e.g. every Remember

e.g. size, etc. In the best scenario the compositor would evaluate such
rules when the client is about to be mapped.
This change limits window rules only to xdg-shell clients because right
now only this protocol lets compositors to intervene in the client
initialization process. Also, it makes things a bit easier for us on the
compositor side.
xdg-shell protocol satisfies most of ours requirements to implement window
rules, but not all of them. If the client is about to be mapped for the
second time and its size is forced by a rule, then compositor may need
to configure it. Currently, xdg-shell protocol doesn't have any mechanism
that a client could use to notify the compositor about its intent to map.

Summary:
If you resize a decorated client by using the resize user action(press
Alt + F3 > More Actions > Resize), then KWin will crash because it gets
stuck in an infinite loop (AbstractClient::performMoveResize <->
ShellClient::setGeometry).
Here's how KWin gets stuck in that loop:
* when you finish resizing the client, AbstractClient::keyPressEvent
will call AbstractClient::finishMoveResize;
* the first thing that finishMoveResize does is block geometry updates,
then it does some clean up (e.g. reset the value of isMoveResize(), etc),
updates the geometry of the client and when it's done, it will emit
clientFinishUserMoveResized signal;
* when PointerInputRedirection notices that signal, it will call
processDecorationMove on the client, which in its turn will indirectly
call AbstractClient::startMoveResize;
* when it's time to go back to AbstractClient::keyPressEvent, geometry
updates are unblocked and if there are any pending geometry updates,
then ShellClient::setGeometry will be called;
* ShellClient::setGeometry will eventually call ShellClient::doSetGeometry;
* ShellClient::doSetGeometry will call AbstractClient::performMoveResize
because AbstractClient::processDecorationMove indirectly called
AbstractClient::startMoveResize;
* AbstractClient::performMoveResize calls ShellClient::setGeometry;
* (at this point, KWin got stuck in the infinite loop)
This change swaps setMoveResizePointerButtonDown and finishMoveResize,
so processDecorationMove won't indirectly call startMoveResize.
