* Avoid float to int warning. * Work around 'using namespace' bug in Visual C++. * Make `<boost/functional/hash/extensions.hpp> self contained. * Move some of the extension implementation from the main hash header into the exensions header. * Remove BOOST_HASH_CHAR_TRAITS from `container_fwd.hpp`. * Other minor changes.
