NetworkManager/libnm-glib/nm-remote-settings.c
Dan Winship 8ad3ff24ad libnm-glib: don't use client-side generated dbus-glib bindings 
Most of the code was using dbus_g_proxy_call() directly, but there
were some leftover uses of the generated bindings. Make things more
consistent by using dbus_g_proxy_call() everywhere, and stop building
the -bindings.h files.
