* When the list of plugins is not specified via "main.plugins" in
  NetworkManager.conf and no build-time default is set with
  "--with-config-plugins-default" configure argument, now all known
  plugins found in the plugin directory are loaded (and the built-in
  "keyfile" plugin is preferred over others).
* The hostname received from DHCP is now shortened to the first dot
  (or to 64 characters, whatever comes first) if it's too long.
