Subject: [PATCH 1/2] correct naming of threadsafe_stack

- there is only one instance of "thread_safe_stack" in the entire book (this example)
- in every other instance, the container is named "threadsafe_stack" (only one underscore)

Subject: [PATCH 2/2] opt for `std::shared_ptr<>` over `boost::shared_ptr<>`

- listing 6.1 does not use boost::shared_ptr<> (there don't seem to be any other instances of boost::shared_ptr<> in the book)
- we can either change this or modify 6.1 (although we need to modify it anyway to prevent the throw)
