1. Make inclusion of boost/bind/bind.hpp conditional in some cases, when the code actually conditionally uses boost::bind. Reduces compile-time overhead and fixes https://github.com/boostorg/thread/issues/307. 2. Remove some unnecessary uses of boost::ref. This allows to avoid including boost/core/ref.hpp in a few places, and avoids the associated template instantiation overhead in others. 3. Replace deprecated header includes with the more recent alternatives. For example: boost/detail/lightweight_test.hpp -> boost/core/lightweight_test.hpp, boost/ref.hpp -> boost/core/ref.hpp. 4. Replace some blanket includes with the more fine-grained ones. For example, boost/utility.hpp, boost/atomic.hpp. This reduces compile time overhead. 5. Add some missing includes, for example, boost/core/ref.hpp and boost/type_traits/is_same.hpp. 6. Replace uses of std::is_same with boost::is_same (with the corresponding included header) since the standard type_traits header presence and validity is not tested by the code. Using boost::is_same makes the code more portable.
