    miniobject: Add parent pointers to the miniobject to influence writability · 6fa35140
    Sebastian Dröge authored
    Every container of miniobjects now needs to store itself as parent in
    the child object, and remove itself again at a later time.
    
    A miniobject is only writable if there is at most one parent, and that
    parent is writable itself, and if the reference count of the miniobject
    is 1.
    
    GstBuffer (for memories), GstBufferList (for buffers) and GstSample (for
    caps, buffer, bufferlist) was updated accordingly.
    
    Without this it was possible to have e.g. a bufferlist with refcount 2
    in two places, modifying the same buffer with refcount 1 at the same
    time.
