Thomas Haller fa9fe466db libnm: avoid constructor function for registering NMSetting types 
constructor functions are ugly, because code is running before
main() starts. Instead, as the registration code for NMSetting types
is insid the GType constructor, we just need to ensure at the
right place, that the GType was created.

The right place here is _register_settings_ensure_inited(), because
that is called before we need the registration information.
