    libswan: Introduce and exploit EMPTY_CHUNK and CHUNKO(); delete CHUNK()
    
    - EMPTY_CHUNK is a literal constant equal to empty_chunk.  Being a
      literal it should allow for better static analysis (better code
      generation and better compiler diagnostics).
    
    - CHUNKO() creates a chunk for an object
    
    - CHUNK() was never used but was like CHUNKO. It could only be used as
      an initializer, and only if the object were an array (surely a bug).
