[boost] Boost.Quaternion and Koenig lookup

Hello,

I noticed that the regression test of Boost.Quaternion did not compile in
Comeau non-strict (Microsoft) mode. Looking deeply, it seems that the
problem is only that it relieson Koenig lookup in several points. Since we
already define a macro to detect the presence of this feature, I fixed it
quickly.

quaternion.hpp, add at line 48:

#ifdef BOOST_NO_ARGUMENT_DEPENDENT_LOOKUP
  using    ::std::abs;  // for abs(valarray<>)
#endif

quaternion_test.cpp, add at line 32:

#ifdef BOOST_NO_ARGUMENT_DEPENDENT_LOOKUP
using    ::boost::math::real;
using    ::boost::math::unreal;
using    ::boost::math::sup;
using    ::boost::math::l1;
using    ::boost::math::abs;
using    ::boost::math::norm;
using    ::boost::math::conj;
using    ::boost::math::exp;
using    ::boost::math::pow;
using    ::boost::math::cos;
using    ::boost::math::sin;
using    ::boost::math::tan;
using    ::boost::math::cosh;
using    ::boost::math::sinh;
using    ::boost::math::tanh;
#endif

Boost.Octonion requires a similar patch. If needed, I can provide the full
patch for it as well.
