Fix #132314.

2004-01-27  Federico Mena Quintero  <federico@ximian.com>

	Fix #132314.

	* gtk/gtkfilesystem.h: Removed the #ifdef-ed out, old icon API.

	* gtk/gtkfilesystem.c: Likewise.

	* gtk/gtkfilesystemunix.c (filename_get_info): Removed the old
	icon-type code.
	(gtk_file_system_unix_render_icon): Moved the icon-rendering code
	from GtkFileInfo to here.
	(gtk_file_system_unix_volume_render_icon): Implement.
