        that duplicate fields in ctf_file: move allocation of ctf_file
        further up instead.  Call upgrade_header as needed.  Move
        version-specific ctf_parmax initialization into upgrade_types.  More
        concise error handling.
        (ctf_file_close): No longer test for null pointers before freeing.

        Fix the compression length: fp->ctf_size never counted the CTF
