dup/dup2 now encode their ownership semantics in the type system. Special variants of dup2 were added for the I/O redirection which we use here. dup now takes an Fd instead of a RawFd and returns an OwnedFd, which is directly convertible to a File, so we can get rid of some conversion boilerplate in get_file_handle.
