LayoutManager2.java: Merged with Classpath.

Browse source 
* java/awt/LayoutManager2.java: Merged with Classpath.
	* java/awt/LayoutManager.java: Merged with Classpath.
	* java/awt/GridLayout.java: Updated copyright and javadoc.
	(getSize): Use `parent.ncomponents'.  Handle insets.
	(layoutContainer): Use `parent.ncomponents'.  Handle case where
	there are fewer children than columns.  Correctly compute size of
	each cell in the grid.  Handle case where there isn't enough
	space.
	* java/awt/CardLayout.java (tab): Renamed from `map'.  Updated
	all users.
	(gotoComponent): Use parent.ncomponents.  Ensure child exists
	before calling setVisible() on it.  Last item is `num - 1', not
	`num'.
	(layoutContainer): Hoist invariants out of loop.
