29505630ea Use references for the ExceptionStackFrame argument 
We require/assume that these pointers are correct. Using references is cleaner than blindly dereferencing raw pointers.

Important: The Rust book guarantees that: “At runtime, a raw pointer * and a reference pointing to the same piece of data have an identical representation.”

987c56a153 Create a new print function and use it in the print macro 
This fixes the deadlock problem, because the format_args is now evaluated before locking the screen writer. So `println!("{:?}", {println!("");})` no longer triggers a deadlock.
