Changes since 1.3: +28 -1 lines

fix lib/31874.
- add _citrus_stdenc_get_state_desc() interface to get
  encoding-scheme-independent encoder/decoder state descriptions.
- make sure that iconv_std module uses it to judge whether the last
  sequences forms complete shift sequences.
- bump minor of i18n_module because of get_state_desc().
