AU: Beginnings of dbus support.
The AU will be a daemon that runs as root. Non-root will communicate
via dbus with the updater to do things such as: query status, request
forced or full updates, etc.
New files for dbus:
UpdateEngine.conf - security configuration
dbus_constants.h - common constants
dbus_service.* - The object exposed over dbus
org.chromium.UpdateEngine.service - the dbus service file
udpate_attempter.* - Refactored this out of main.cc
update_engine_client.cc - Simple command line utility to interact with
Update Engine over dbus. Whereas Update Engine runs as root, this tool
runs as non-root user.
