PROTON-865: Stream like Encoder/Decoder and AMQP Value type for C++ binding. See Encoder.h, Decoder.h, Value.h for details. Encoder/Decoder use operator << and >> to encode/decode AMQP values. Value is a variant-like type that can hold an arbitrary AMQP value. Simple types are implemented, complex types coming next.
