Added header files that use c++11 variadic templates instead of ruby code generation.

When the compiler configured to support C++11 (e.g. CXXFLAG contains -std=c++11 is given),
those files are used.
Decoupled unpacker and msgpack_unpacker.
This modification introduced C++11 dependency such as nullptr and unique_ptr.
I will support C++11 and C++03, finally.

Decoupled msgpack.hpp and msgpack.h.

Decoupled sbuffer from msgpack_sbuffer.

Decoupled vrefbuffer from msgpack_vrefbuffer.

Decoupled zbuffer from msgpack_zbuffer.

Added some z_stream initialization.

Removed unpack macros.

Removed CTX_CAST and CTX_REFERENCED.

Embed ctx_ as a member variable (not a pointer).

Modified zone free using C++ way.
