Fix regression introduced by e4becdc3d3
Add QPlatformDrag::ownsDragObject() function, QDragManager can use the
return value of this function to decide if it should take care of deleting
QDrag object or platform plugin will take care of deleting QDrag.
XCB platform plugins uses async dnd data delivery mechanism. It allows
user to drop something and then continue working with the assurance that
the target will get the data regardless of how slow the network connections
are, which means that a source window should preserve QDrag data until
dnd has finished.
