6337	support hashing thread::id	Kohei Takahashi <flast@…>	Anthony Williams	"I propose to be able to use thread::id as key type of unordered associative container, add hash_value free function under boost namespace.

Simple implementation is here.
{{{
// Should include boost/functional/hash.hpp
// and declare as friend of thread::id.
std::size_t
hash_value(const thread::id &v)
{
    return hash_value(v.thread_data.get());
