    function: Improve format_function_name()
    
    It's not necessary to pass in the information about whether the function
    is a method or not, it's available from the function's GICallableInfo.
    
    Fix the type of function->info to be GICallableInfo. In some cases it's
    not a GIFunctionInfo, as can be found out by trying to call a
    GIFunctionInfo method on it unconditionally.
