7b948b0647 - Added generic EDNS code for registering known EDNS option codes, 
bypassing the cache response stage and uniquifying mesh states. Four EDNS
  option lists were added to module_qstate (module_qstate.edns_opts_*) to
  store EDNS options from/to front/back side.
- Added two flags to module_qstate (no_cache_lookup, no_cache_store) that
  control the modules' cache interactions.
- Added code for registering inplace callback functions. The registered
  functions can be called just before replying with local data or Chaos,
  replying from cache, replying with SERVFAIL, replying with a resolved
  query, sending a query to a nameserver. The functions can inspect the
  available data and maybe change response/query related data (i.e. append
  EDNS options).
- Updated Python module for the above.
- Updated Python documentation.

  forwarder, but CD bit thereafter on repeated attempts to get DNSSEC.
