add libbatteryservice
IBatteryPropertiesListener is used by clients such as BatteryService to
receive notifications of changed battery/power status (from healthd).
IBatteryPropertiesRegistrar manages registrations of
IBatteryPropertiesListener clients.
Add BatteryService native header with defines from BatteryManager, and
class BatteryProperties to pass battery/power status around.
