AU: DBus support.
A few changes to support dbus in the Update Engine daemon:
- SConstruct: build marshaller for the dbus signal.
- Update Attempter: respond to dbus calls and broadcast status on dbus
signal.
- Update Engine Client: flag to listen for status updates.
- Also, cleanup outdated code in Omaha Response Handler.
