geez, don't call g_list funcs on GSList

	* gtk/gtktextbuffer.c (gtk_text_buffer_remove_all_tags): geez,
	don't call g_list funcs on GSList

	* gtk/gtkwidget.c (gtk_widget_child_focus): replaces
	gtk_container_focus(), since some widgets have focusable locations
	which are not other widgets. These widgets should not have to be
	containers just to manage the focus. For example, GtkHSV is
	currently a container for no good reason. Also, this cleans
	up the "if (is_container && is_sensitive && is_drawable)
	container_focus ()" mess in widget implementations.

	* gtk/gtkcontainer.c (gtk_container_focus): deprecate this
	function, and have it just call gtk_widget_child_focus().

	* gtk/gtkhsv.c: derive from widget not container

	Throughout: fix to reflect GtkContainer::focus change
