    gsignal: Drop unnecessary warnings from g_signal_lookup()
    
    The `G_TYPE_IS_INSTANTIATABLE()` check is redundant with a precondition
    on the function.
    
    The `g_type_class_peek()` check seems like a pointless restriction: it
    should be possible to check for a signal from a class init function.
