This function also calls g_weak_ref_set() with @object on the
freshly-initialised weak reference.
This function should always be matched with a call to
g_weak_ref_clear(). It is not necessary to use this function for a
#GWeakRef in static storage because it will already be
properly initialised. Just use g_weak_ref_set() directly.
