Script and BIF functions with a single any parameter are excluded from type checking regarding arguments. This makes it possible to call a ScriptFunc with more arguments than it actually has parameters and frame space for, causing heap-buffer-overflows. This change runtime checks expected parameters and provided arguments and short-circuits execution as well as logging runtime expression errors. Fixes #2446
