Related: #377

Notes:
- the attributes in the operation list is not really good, we probably
  need to specify better what parameters are used in the .doit() function
  (though the generated code is the same). Specifying 'remote_addr'
  either in 'request' or in 'reply' would  probably make patch 2/5 useless.
- I didn't add the multicast groups on purpose. ynl-c.py is not able to
  generate the operation list for genetlink-legacy, so all this part
  (including multicast groups) needs to be left unspecified in the
  template.
