Refactor string handling in util
The util module provides helper methods to deal with the C strings returned by libnitrokey. The current implementation has to problems: - It causes unnecessary allocations if we only want to look at the string, for example in get_serial_number. - If the conversion from a CStr to a String fails, the string pointer is not freed. Therefore this patch introduces the run_with_str function that executes a function with the string returned by libnitrokey and then makes sure that the pointer is freed correctly.
