These classes should not inherit from each other
anymore in Qt 6. The reason is that this makes
the 95% case of using a non-recursive mutex
much slower than it has to be.
This way, QMutex can now inline the fast path
and be pretty much as fast as QBasicMutex is
in Qt 5. They actually use the same code paths
now. The main difference is that QMutex allows
calling tryLock() with a timeout, which that
is not allowed for QBasicMutex.
[ChangeLog][QtCore][QMutex] QMutex does not support
recursive locking anymore. Use QRecursiveMutex for that
purpose. QRecursiveMutex does not inherit QMutex anymore
in Qt 6.

When configuring an example like
widgets/tools/plugandpaint/plugins/basictools outside of a Qt build,
the configuration fails because it tries to call the internal function
instead of the public one.
This was needed some time ago to facilitate moving from qt_add_plugin
to qt_internal_add_plugin, so some compatibility code was added.
But we've now migrated to qt_internal_add_plugin across most repos,
so we should remove the compatibility code to allow examples to
configure successfully.

If a model only allows MoveAction, then calls in the view/widget subclasses'
dropEvent implementation to set the event's drop action to CopyAction
will fail. QAbstractItemView will then remove the item when QDrag::exec
returns.
Instead of abusing the event actions for this, store explicitly that the
dropEvent implementation already moved the item. If the flag is set,
don't remove the item.
In QListView, which uses moveRow to move items in the dropEvent handler,
handle the case that the model might not implement moveRows. In that
case, or when dropping an item onto another item (to overwrite data),
fall back to the default implementation of QAbstractItemView. Sadly, it
is impossible to know whether a model doesn't implement moveRows, or
whether the move failed for other reasons, so this requires a bit of
extra special case handling. QListView in IconMode is particularly odd
in that it moves the item in the view, but not in the model.
This follows up on fd894fd68e and fixes
additional issues discovered during debugging. Extend the existing unit
test; since drag'n'drop runs a modal, native event loop on most systems,
it still only runs on the Xcb platform.

is adopting the object from a Q(E)SDP into a different reference

Also, the API for the shared data pointer classes should

Originally this was there for qdoc, but from the qtdeclarative API
review it becomes clear that we need this also when an application
- that includes Qt Quick headers which in turn want to use VkImage
and co. for type safety - is built on a system without vulkan.h
against a Vulkan-enabled Qt build.
Also fix some of the typedefs which were technically incorrect. (not
that it matters much since the dummy typedefs still do not allow
calling exported Qt functions that use the real Vk* types since the
function signatures like won't match in some cases (would need to
replicate too much hocus pocus from vulkan.h for that), but that's fine
since our goal here is to keep application compilation going when it
encounters a Vk* type in a Qt header, not about enabling actually
calling those functions)
