New function, doing the same as g_convert but taking a GIConv argument.

2001-08-24  Alexander Larsson  <alla@lysator.liu.se>

	* glib/gconvert.[ch] (g_convert_with_iconv):
	New function, doing the same as g_convert but taking
	a GIConv argument. The old g_convert is just
	a call to this with a newly opened GIConv.
