MmsManager picks up client app's attribution tag and send it to MmsServiceBroker.
MmsServiceBroker includes it in the call to noteOp. It then calls MmsService sendMessage and pass it along.
These changes are applied to sendMessage and downloadMessage methods only.
Null entries are passed to noteOp methods in other methods like importTextMessage, etc.
These methods were removed from MmsManager(ag/9431535), but not removed from IMms.
