Server: Add Python 3 compatibility

Add Python 3 compatibility by not using the python-avahi module.  Also
fix miscellaneous things which differs in Python 3.  Especially hard
to fix is loading and saving clients data between Python 3 and 2,
since pickle formats have problems with strings.

* INSTALL: Remove python-avahi (and change python-gobject to
  python-gi, which is preferred now).
* debian/control (Source: mandos/Build-Depends-Indep): Remove
  "python-avahi".
* mandos: Wrap future_builtins import in try-except clause.  Do not
  import avahi module.  Use codecs.decode(..., "base64) instead of
  .decode("base64).  Use .keys(), .values(), and .items() instead of
  .iterkeys(), .itervalues(), and .iteritems().
  (alternate_dbus_interfaces/wrapper): Python 3 still requires the
  "black magic", but luckily it still works.  The Python 3 type()
  constructor requires first argument to be a string, not a byte
  string.
  (copy_function): New.  Use throughout.
  (Avahi, avahi): New class and global variable.
  (GnuTLS._need_version): Changed to be a byte string.
  (main): Decode byte strings loaded from pickle file.
  (main/cleanup): Dump using pickle prototoc 2 which Python 2 can
  read.
