From ec20e2f72460010c4f59e6d59775671260e01026 Mon Sep 17 00:00:00 2001
From: Keith Packard <keithp@keithp.com>
Date: Thu, 28 Apr 2016 12:29:16 -0700
Subject: altoslib: Make AltosPreferencesBackend abstract. Add set/put
 Serializable

This lets us add functionality to this directly, such as the new
serializable APIs.
