* io.c (io_ungetc): raise NotImplementedError when ungetc is called

Browse source 
against dummy encoding IO.

* io.c (rb_io_getline_1): ditto when gets with delimiter is called.

* io.c (io_getc): ditto when getc is called.

* test/ruby/test_io_m17n.rb (test_terminator_stateful_conversion,
  test_getc_stateful_conversion, test_ungetc_stateful_conversion):
  these tests should raise NotImplementedError.
