Add BOOST_NO_STD_TYPEINFO or inject ::type_info into std

[Peter Dimov]

//  MACRO:         BOOST_NO_STD_TYPEINFO
//  TITLE:         type_info not in namespace std
//  DESCRIPTION:   The <typeinfo> header declares type_info in the global namespace instead of std

#include <typeinfo>

namespace boost_no_std_typeinfo
{

int test()
{
   std::type_info * p = 0;
   return 0;
}

}

A better alternative to this macro may be to inject ::type_info into namespace std in suffix.hpp, but we still need a way to detect that the compiler needs the workaround. So it might be best to do both. Unfortunately this may interfere with config_test.

Added to SVN trunk, will leave open till it's merged with 1.35 release branch (when we have one).

Now that we have a release branch and we know that most libs will be merged to it, I'm closing this one down as fixed.
