Remove BOOST_NO_EXPLICIT_FUNCTION_TEMPLATE_ARGUMENT

This makes boost::config independent of boost::core in the
modularized repos.

(from Stephen Kelly)

Daniel James: The original patch included changes for several libraries.
I'll deal with them later, they shouldn't break since the changes were to
remove code that won't be activated any more.

-// Some compilers have problems with function templates whose template
-// parameters don't appear in the function parameter list (basically
-// they just link one instantiation of the template in the final
-// executable). These macros provide a uniform way to cope with the
-// problem with no effects on the calling syntax.
 
-// Example:
+// These macros are obsolete. Port away and remove.
-//
-//  #include <iostream>
-//  #include <ostream>
-//  #include <typeinfo>
-//
-//  template <int n>
-//  void f() { std::cout << n << ' '; }

-//    g<int>();
-//    g<double>();
-//  }

-// With VC++ 6.0 the output is:

-//   2 2 double double
