akr 6270ad5b7f * include/ruby/encoding.h (rb_econv_asciicompat_encoding): renamed
from rb_econv_stateless_encoding to apply stateless ASCII
  incompatible encodings such as UTF-16BE.

* io.c (make_writeconv): use rb_econv_asciicompat_encoding.

* transcode_data.h (rb_transcoder_asciicompat_type_t): renamed from
  rb_transcoder_stateful_type_t.
  (rb_transcoder): use rb_transcoder_asciicompat_type_t.

* transcode.c: follow the type change.
  (asciicompat_encoding_i): renamed from stateless_encoding_i.
  (rb_econv_asciicompat_encoding): renamed from
  rb_econv_stateless_encoding.
  (econv_s_asciicompat_encoding): method renamed.

* tool/transcode-tblgen.rb: follow the type change.

* enc/trans/utf_16_32.trans: follow the type change.
  rb_from_UTF_16BE to UTF-8 is asciicompat_decoder.
  rb_from_UTF_16LE to UTF-8 is asciicompat_decoder.
  rb_from_UTF_32BE to UTF-8 is asciicompat_decoder.
  rb_from_UTF_32LE to UTF-8 is asciicompat_decoder.

  UTF-8 to rb_to_UTF_32BE is asciicompat_encoder.
  UTF-8 to rb_to_UTF_32LE is asciicompat_encoder.

* enc/trans/newline.trans: follow the type change.  universal newline
  decoder is asciicompat_converter.
