  SVN rev 219827 on 2011-03-21 14:18:40Z by glebius
  
  Improve locking of creating and dropping links in the graph, acquiring
  the topology mutex in the following functions, that manipulate pointers
  to peer nodes:
  
  - ng_bypass()
  - ng_path2noderef() when switching to the next node in sequence.
    Rewrite the function a bit.
  - ng_address_hook()
  - ng_address_path()
  
  This patch improves stability of large mpd5 installations.
