rubygen/0-10/specification.rb:

 - Simplified enum mapping/encoding.
 - struct encoding
 - ostream << operators
  
src/qpid/Serializer.h
 - free funciton serialization
 - separate Encoder/Decoder for const correctness
 - split() to allow separate encode/decode for complex cases.

src/qpid/amqp_0_10/Assembly.cpp, Assembly.h: AMQP 0-10 final Assembly

src/qpid/amqp_0_10/Codec.h
 - Replaced enable_if with overloads, simpler & more flexible.

src/qpid/amqp_0_10/Frame.cpp, .h: AMQP 0-10 final frame.

src/qpid/amqp_0_10/Holder.h:
 - provide const and non-const apply 

src/qpid/amqp_0_10/Segment.cpp, .h: AMQP 0-10 final Segment.

src/qpid/amqp_0_10/apply.h
 - ConstApplyFunctor for const apply.

src/qpid/amqp_0_10/built_in_types.h
 - SerializableString encoding
 
src/qpid/amqp_0_10/complex_types.cpp, .h
 - const application
 - Action base class for command/control.
 
src/qpid/framing/AMQBody.h
 - removed 0-10 final changes, moving integration point down the stack.
 
src/qpid/sys/Shlib.h
 - removed unused and uncompilable (on some compilers) function.
 
src/qpid/sys/Time.h, .cpp
 - ostream << for AbsTime and Duration.
 
src/tests/Assembly.cpp, Segment.cpp, apply.cpp, serialize.cpp: testing new code.
