    csstypes: Change NTH_CHILD and NTH_LAST_CHILD change propagation
    
    For now assume that if those flags change for a node, they also changed
    for all sibling nodes. This is not strictly true but simplifies
    invalidation.
    
    The reason it simplifies invalidation is that when removing or adding a
    node, we can just invalidate the first node (for NTH_LAST_CHILD) and the
    new node (for NTH_CHILD) and all the other nodes will be invalidated
    automatically.
