Very primitive wallpapers in a surface.

This is all of the basic pieces:

- The WallpaperService now creates a surface with the window manager for its
  contents.
- There is a simple service that displays a bitmap.
- The wallpaper manager takes care of starting and stopping the service.
- The window manager knows about wallpaper windows and how to layer them with
  the windows that want to be shown on top of wallpaper.

Lots and lots of issues remain, but at this point you can actually write a
wallpaper service, select it in the UI, and see it behind an activity.
