Summary:
This change standardizes the behavior regarding the destructor request.
The destructor should destroy the resource and nothing else. The
Wayland library invokes the static unbind method once the resource is
destroyed. The implementation provided by Resource::Private::unbind
triggers a delete later on the Resource. So there is no need to trigger
a deleteLater from the destructor request callback.
This change adds a generic implementation to Resource::Private which is
now used by all inheriting classes replacing the custom implementations.
Test Plan:
For a few Resources the test is extended to ensure that the Resource
gets deleted on server side.

Summary:
This is a workaround for https://bugreports.qt.io/browse/QTBUG-52118
It should take effect whenever the parent surface's state is applied,
but QtWayland never commits the parent surface. Thus the position is
always wrong.
Having a workaround for that in our server code is not good, but better
than completely broken applications such as Systemsettings.

Summary:
From spec:
If the wl_surface associated with the wl_subsurface is destroyed,
the wl_subsurface object becomes inert. Note, that destroying either
object takes effect immediately.

Summary:
Recursively go up to the main surface, that is the top level surface
which doesn't have a parent.
This is useful to know to which surface tree a sub-surface belongs to.

When committing the state of a sub-surface, the state should not
be immediately applied if the sub-surface is in synchronized mode.
Instead it should be cached and only applied after the parent surface's
state is applied.
To implement this the Surface::Private has now a third cached state
buffer. When committing the state is either swapped between pending and
current or pending and subSurfacePending. Once the parent state is
applied the state is swapped between subSurfacePending and current.
The logic for applying state changes is changed. Instead of copying the
complete state object, the individual state changes are now copied and the
source gets completely reset to default values. Only the children tree is
copied back, as that list needs to be modified.
The mode is not sufficient to determine whether a SubSurface is in
synchronized mode.
Quoting spec:
"Even if a sub-surface is in desynchronized mode, it will behave as in
synchronized mode, if its parent surface behaves as in synchronized mode.
This rule is applied recursively throughout the tree of surfaces.
This means, that one can set a sub-surface into synchronized mode, and
then assume that all its child and grand-child sub-surfaces are
synchronized, too, without explicitly setting them."
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.
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.
This implements the subcompositor and subsurface protocol on both
Client and Server side.
Client:
New classes SubCompositor and SubSurface. The SubCompositor can be
created through the Registry and creates the SubSurface which is
bound to a Surface and has a parent Surface. The SubSurface class
provides convenient wrappers for all calls exposed in the
wl_subsurface interface.
Server:
New classes SubCompositorInterface and SubSurfaceInterface. Support
for all commands is added, though the API probably still can need
some fine tuning. The synchronized vs. desynchronized behavior is
not yet exposed in the API. This could also be delegated towards
the user of the library.
