Refactor for multi-display support.

Split WindowManagerImpl into two parts, the WindowManager
interface implementation remains where it is but the global
communications with the window manager are now handled by
the WindowManagerGlobal class.  This change greatly simplifies
the challenge of having separate WindowManager instances
for each Context.

Removed WindowManagerImpl.getDefault().  This represents the
bulk of this change.  Most of the usages of this method were
either to perform global functions (now handled by WindowManagerGlobal)
or to obtain the default display (now handled by DisplayManager).

Explicitly associate each new window with a display and make
the Display object available to the View hierarchy.

Add stubs for some new display manager API features.

Start to split apart the concepts of display id and layer stack.
since they operate at different layers of abstraction.
While it's true that each logical display uniquely corresponds to a
surface flinger layer stack, it is not necessarily the case that
they must use the same ids.  Added Display.getLayerStack()
and started using it in places where it was relatively easy to do.
