rust-cpython: add panicking version of borrow_mut() and use it The original borrow_mut() is renamed to try_borrow_mut(). Since leak_immutable() no longer incref the borrow count, the caller should know if the underlying value is borrowed or not. No Python world is involved. That's why we can simply use the panicking borrow_mut().
