Add BOOST_NO_TYPEID

[Peter Dimov]

//  MACRO:         BOOST_NO_TYPEID
//  TITLE:         typeid unavailable
//  DESCRIPTION:   The compiler does not support typeid in this mode

#include <typeinfo>

namespace boost_no_typeid
{

int test()
{
   typeid(int);
   return 0;
}

}

Note that this is not the same as "no RTTI". RTTI only comes into play when typeid is used on an expression of a polymorphic type. Compilers may (and do) still support typeid in "no RTTI" mode.

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.
