Motivation: We have different message aggregator implementations for different protocols, but they are very similar with each other. They all stems from HttpObjectAggregator. If we provide an abstract class that provide generic message aggregation functionality, we will remove their code duplication. Modifications: - Add MessageAggregator which provides generic message aggregation - Reimplement all existing aggregators using MessageAggregator - Add DecoderResultProvider interface and extend it wherever possible so that MessageAggregator respects the state of the decoded message Result: Less code duplication
