Update.

	* iconv/gconv_cache.c (find_module): Don't allocate room for the
	filename.  Use alloca, we don't need it beyond this function.
	(__gconv_release_cache): New function.
	* iconv/gconv_db.c (__gconv_close_transform): Call
	__gconv_release_cache after the steps are handled.
	* iconv/gconv_dl.c (__gconv_find_shlib): Allocate file name in the
	record as well.
	* iconv/gconv_int.h: Add prototype fpr __gconv_release_cache.
