eina: add a C++ bindings to Eina @feature.

The goal of this library is to make the life of C++ developers easier
when having to manipulate Eina datatype by providing a layer to abstract
those data type in C++. Check examples for now. Documentation will come
soon, but we are pushing that rather sooner to get feedback on those bindings.

As you will notice, this library is just composed of headers. There is no .so
and we do think it is better this way. Reducing ABI and API stability issue for
applications developers who are the primary target of this binding.

Also please note that you will need to have C++11 to use this binding.
