* transcode.c (transcode_loop): take destination and resize function

Browse source 
as parameters.
  (more_output_buffer): ditto.
  (str_transcoding_resize): argument changed from rb_transcoding* to
  VALUE.
  (str_transcode): call transcode_loop with destination string and its
  resize function.

* transcode_data.h (rb_transcoding): move ruby_string_dest and
  flush_func to transcode_loop parameters.
