    smartlist.rs: The libc::c_char type is not the same as i8.
    
    The code had been using c_char and i8 interchangeably, but it turns
    out that c_char is only i8 on platforms where "char" is signed. On
    other platforms, c_char is u8.
    
    Fixes bug 24794; bug not on any released Tor.
