* transcode.c (transcode_restartable0): return econv_incomplete_input
  for unexpected end of source buffer.
  (trans_sweep): check econv_incomplete_input.
  (rb_trans_conv): ditto.
  (rb_econv_convert0): ditto.
  (rb_econv_convert): ditto.
  (transcode_loop): ditto.
  (make_econv_exception): change message for econv_incomplete_input.
  (econv_result_to_symbol): return :incomplete_input for
  econv_incomplete_input.
  (ecerr_incomplete_input): new method.
