	(__gconv_fct): New parameter with starting position in output buffer.
	(__gconv_trans_fct, __gconv_trans_context_fct, __gconv_trans_query_fct,
	__gconv_trans_init_fct, __gconv_trans_end_fct): New types.
	(struct __gconv_step): Add new member __trans.
	* iconv/gconv_int.h: Pretty print prototypes.
	(gconv_transliterate): New prototype.

	step and step_data structure.  Remove optimization for BODY with
	NEED_LENGTH_TEST == 0.
	* iconv/gconv_simple.c: Update interfaces of functions.  Insert
