Issue MESOS-4678: Upgrade vendored Protobuf to 2.6.1
We currently vendor Protobuf 2.5.0. We should upgrade to Protobuf 2.6.1. This introduces various bugfixes, performance improvements, and at least one new feature we might want to eventually take advantage of ({{map}} data type). AFAIK there should be no backward compatibility concerns.
