Check for interior nulls in .to_c_str()

Browse source 
Previous dicussions about CString suggested that interior nulls should
throw an error. This was never implemented. Add this now, using a
condition (named null_byte) to allow for recovery.

Add method .to_c_str_unchecked() that skips this check.
