Instead of a raw AIDL interface, give DropBox a Java
interface (android.os.DropBox); move the Binder interface behind the scenes. Make DropBoxEntry into DropBox.Entry. Make it possible to get a dropbox from an (Application)Context with the usual getSystemService(DROPBOX_SERVICE) type thing. Update the tests accordingly.
