Change the GDT push logic
...
Instead of looking for a zero field, we now keep track of the next free index in a separate field. This avoids the bug that the high u64 of a pushed TSS descriptor is treated as empty.

Test the handler_with_error_code macro in a different way

We now take stack_frame as a immutable reference and we shouldn't write to a &. So the old test example (page faults as breakpoints) becomes even more hacky. Instead, we're now deliberately entering an endless page fault loop to check our iretq logic.

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.”
