C++ Generator: MessageHeader copy-constructor broken

[ksergey]

Hi,

Latest stable release generate incorrect copy-constructor for MessageHeader:

    MessageHeader(const MessageHeader& codec) :                                                                                                    
        m_buffer(codec.m_buffer), m_offset(codec.m_offset), m_actingVersion(codec.m_actingVersion){} 

Missed m_bufferLength copying

I believe copy-constructor and copy-operator could be default

#if __cplusplus >= 201103L
MessageHeader(const MessageHeader&) = default;
MessageHeader& operator=(const MessageHeader&) = default;
#endif

Also why you support old c++ standard? I believe will be reasonable to require c++11 for generated code.

Thanks

I've fixed the bug but will let @tmontgomery comment on approach.

For MessageHeader (and composites), defaults would work. But the generator reuses some of the logic from the message codecs. Which can't use default.
