libnm: port to GDBusdanw/libnm-gdbus

Port libnm-core/libnm to GDBus.

The NetworkManager daemon continues to use dbus-glib; the
previously-added connection hash/variant conversion methods are now
moved to NetworkManagerUtils (along with a few other utilities that
are now only needed by the daemon code).
