The ShellSurface might have the resource destroyed, before being deleted,
so there is a short time frame where resource might be null.
Crash was caught by KWin.

Summary:
So far the server component performed manual cleanup in some cases
when a client disconnects. But this is not needed: the Wayland library
calls the static unbind methods which do cleanup. If we cleanup ourselves
this can result in double deletes in the worst case, so let's only use
the Wayland functionality.
Adjusted:
* RegionInterface
* SurfaceInterface
* ShellSurfaceInterface (doesn't take a parent anymore)
* DpmsInterface
* QtSurfaceExtensionInterface
* KeyboardInterface
* PointerInterface
* TouchInterface
* DataOfferInterface
* PlasmaShellSurfaceInterface
For each adjusted case a test case is added to verify that the cleanup
works. Exceptions are DpmsInterface as the actual Resource is not exposed
at all in the Server component and DataOfferInterface as that is server
side created.

This patch transports the EDID data base64-encoded over the wire.
Apparently, we can't just send random QByteArrays as "strings" over, it
has to be encoded and decoded. So...
* base64-encode the data before sending to the client
* base64-decode it on the client side
* document the above, fix documentation woes in the xml definition
* change test accordingly
The test data used was actually invalid, it's a base64 string of the
actual data, so fix the tests (which actually breaks it), and encode on
the server-side and decode on the client side.

After deleting an OutputInterface the resources are not necessarily
destroyed, so unbind might still be called. The existing code just
casted the resource's user data which could then point to invalidated
memory.
This change verifies that we still have a Private* for the resource.
If not, it doesn't have to do any cleanup anyway.

This implements the server part of the screen management protocol. The
protocol is implemented as a wayland protocol.
It provides the following mechanisms:
- a list of outputs, close to wl_output, with additional properties for
enabled, uuid, edid, etc.. These OutputDevices correspond to a
connected output that can be enabled by the compositor, but is not
necessarily currently used for rendering.
- a global OutputManagement, which allows creating config objects, one
per client. The client can make changes to the outputs through
setScale(outputdevice*, scale) for example.
- an OutputConfiguration resource, that can be handed to a client and
used for configuration. Changes are double buffered here. Only after
OutputConfiguration.apply() has been called, the changes are relayed
over the global OutputManagement.
The compositor is responsible to handle changes.
For a more detailed description, see the API docs in especially
outputconfiguration.h.

A transient surface can indicate through the flags that it does not
want to accept keyboard focus. This is now exposed through a dedicated
method.
REVIEW: 125552
So far transient was a mutual exclusive mode causing a transient window
to not be able to be fullscreen. This seems wrong. Let's have transient
still as a dedicated mode allowing the window to be maximized and/or
fullscreen. Only popup stays a dedicated mode.

On client side a setTransient method is added which wraps the semantic
of wl_shell_surface_set_transient.
On server side both set_transient and set_popup are implemented, though
for popup only the transient part is implemented. In particular the grab
is not yet handled and also no popup done is provided.
For the transient on server side the flags are ignored. Main reason is
that Qt does not use the flag, so testing whether it works is tricky
(needs a test application).

Follows a useful change added in the kwaylandScanner tool the
s_version becomes part of the Private class.
Also fixes the related generation in the tool.
The Qt surface extension is a small protocol to allow exchanging
additional data between QWindows and the compositor. What we are
currently only interested in is the possibility to close a surface
from the Compositor.
Protocol description is copied from QtWayland 5.4.2 branch.
Running real world applications (Xwayland) showed that it doesn't like
at all that we do a dispatch when we are going to flush. This caused
in a very reliable manner a "Connection closed" error in XWayland, taking
down the client and in return the (xwayland-enabled) server.
BufferInterface used to have a SurfaceInterface as parent. This could
result in easily hitting the abort condition that the BufferInterface
was still referenced when it gets deleted by just having one other
user referencing the BufferInterface.
There is no need to have the BufferInterface deleted when the
SurfaceInterface to which it belongs gets deleted. The BufferInterface
will get deleted once it's completely unreferenced and also has a
destroy listener.
Uses eglQueryWaylandBufferWL (if available) to determine the size of the
buffer. In order to do so, the server library links against egl (1) and
one needs to register the EGLDisplay in Server::Display by the user of
the library. For this a new method Display::setEglDisplay is added.
1: not using epoxy as it doesn't wrap the Wayland interfaces yet.
Required information is passed through the ctor of Private.
::create is still virtual as ShellSurfaceInterface is retrieving
client information. This can be fixed once we have a better wl_client
encapsulation class.
The Resource base class is supposed to be used by all interface
classes which get created for a wl_resource.
Most interface classes are adjusted, but there are some exceptions:
* BufferInterface: is different as the wl_resource is already created
* PointerInterface and KeyboardInterface: those two need changes, the
implementation differs from all other interface implementations.
Version and interface get passed to the ctor allowing Global::Private
to implement ::create instead of providing a pure virtual method.
Also the static bind method is added to the Global::Private which
delegates into a pure virtual method.
New base class KWayland::Server::Global which all Interface classes
for a wl_global inherit. Furthermore there is a shared base class
for all the Private classes of that type.
