autoconf love:

* use autoconf to check whether dbus_connection_close() is available and use it
  if it is, don't do those checks based on the D-Bus version.

* Make use of dbus_bus_get_private() if it is available.

* Since D-Bus agreeed on a cononical way to write their name, use that way in
  configure.ac.

* Add configure options to define the UNIX user/group for avahi-autoipd
