* mandos: Remove unused "select" module.  Import "ctypes.util".
  (AvahiError.__init__): Call __init__ of superclass.
  (AvahiService.__init__): Rename keyword arg "type" to "servicetype".
  (AvahiService.rename): Bug fix: use "self.rename_count".
  (Client.__init__): Use "None" instead of "{}" as default value.
  (tcp_handler): Renamed to "TCP_handler".  All callers changed.
  (IPv6_TCPServer.__init__): Don't "return", just call the superclass
                             method.
  (if_nametoindex): Don't import "ctypes.util" here.
  (main): Removed unused variable "main_loop_started".
