Fix the critical part of
	https://bugzilla.novell.com/show_bug.cgi?id=303869
	http://bugzilla.gnome.org/show_bug.cgi?id=476342

* gtk/gtkiconcachevalidator.c (_gtk_icon_cache_validate): To avoid
	massive page-in when starting an application, don't validate icon
	caches unless we have "GTK_DEBUG=icontheme".

* gtk/gtkiconcache.c (_gtk_icon_cache_new_for_path): Tell
	_gtk_icon_cache_validate() that it is not mandatory to do the
	validation.

* gtk/updateiconcache.c (validate_file): Here it *is* mandatory to
	do the validation.
