NetworkManager/libnm/nm-vpn-plugin-old.c
Thomas Haller e761d230c3 libnm: use obj_properties array in libnm and cleanup 
This is not merely cosmetic. I will need the obj_properties
array to lookup GParamSpec by their PROP_* enum value. The
alternative would be lookup by name, which is more expensive.
