  [cid] Signedness revisions. Unsigned checks are simpler. * include/freetype/t1tables.h (CID_FaceInfoRec): Change to unsignd `num_dicts`. * src/cid/cidparse.h (CID_Parser): Change to unsigned `num_dict`. * src/cid/cidgload.c (cid_load_glyph): Updated. * src/cid/cidload.c (cid_load_keyword, parse_fd_array, parse_expansion_factor, parse_font_name, cid_read_subrs, cid_face_open): Updated. * src/cid/cidobjs.c (cid_face_done): Updated. * src/cid/cidparse.c (cid_parser_new): Updated.

     *
     * @Description:
     *   A CID_Parser is an object used to parse a Type 1 fonts very
     *   quickly.
     *
     * @Fields:
     *   root ::
     *     The root PS_ParserRec fields.
     *
     *   stream ::
     *     The current input stream.
     *
     *   postscript ::
     *     A pointer to the data to be parsed.
     *
     *   postscript_len ::
     *     The length of the data to be parsed.
     *
     *   data_offset ::
     *     The start position of the binary data (i.e., the
     *     end of the data to be parsed.
     *
     *   binary_length ::
     *     The length of the data after the `StartData'
     *     command if the data format is hexadecimal.
     *
     *   cid ::
     *     A structure which holds the information about
     *     the current font.
     *
     *   num_dict ::
     *     The number of font dictionaries.
