[split] finagle-core: Tests for BroadcastStatsReceiver

[split] Finagle client/server APIs: s/target/addr/g

Provide uniform naming that makes sense for both client and server.
This is also what Wily calls such names -- they are all forms of
addresses.

("Target" implies a "goal" -- address is more concrete. Not to mention
that address is more standard: most people could answer "what is an
address;" a "target" is not as well defined.)

[split] Unbreak finagle and twitter-server pants build

finagle and twitter-server Pants build is broken after https://reviewboard.twitter.biz/r/167548/, which bumps jackson to 2.2.2.

Since Jackson 2.2, jackson-module-scala_2.9.2's dependency on jackson-core and jackson-databind has been changed to provided, which means, if you need to depend on jackson-module-scala_2.9.2, you also need to explicitly depend on jackson-core and jackson-databind.
