    Skip g_base64_decode_step() in introspection
    
    The length of the caller-allocated (that flag was missing; added as well)
    output array is calculated by a formula, so none of the usual array length
    annotations apply. The state parameters need to be initialized with zero.
    
    Just let them use the basic API.
