6342	c++11 compliance:  Adapt the one_flag to the c++11 interface	viboes	viboes	"The current implementation is doesn't complies completely with c++11 standard 30.4.4	Call once.


{{{
struct once_flag { 
  constexpr once_flag() noexcept;
  once_flag(const once_flag&) = delete; 
  once_flag& operator=(const once_flag&) = delete;
};
}}}

E.g.

{{{
boost::once_flag once;
}}}

fails

and needs

boost::once_flag once=BOOST_ONCE_INIT;

In addition one_flag in not copyable.
