2748	[any] implement reset for direct constructing (adapt to noncopyable)	nowake@…	nasonov	"I modified boost::any to adapt noncopyable object.

(a) add reset members to construct content directory.
(b) modify boost::any::holder

Sample:
 {{{
   struct A {
      A() : v() {};
      A(unsigned int value) : v(value) {};
      unsigned int v;
   };

   BOOST_AUTO_TEST_CASE(test01)
   {
      any test;
      test.reset<A>(10);
      BOOST_CHECK_EQUAL(any_cast<A>(test).v, 10);
      test.reset();
      BOOST_CHECK_EQUAL(test.empty(), true);
   }


   struct B : boost::noncopyable {
      B() : v1(), v2() {};
      B(unsigned int value1, unsigned int value2)
         : v1(value1) ,v2(value2)
      {};
      unsigned int v1, v2;
   };

   BOOST_AUTO_TEST_CASE(test02)
   {
      any test;
      //test = B();                 // compile error
      //test.reset<B>(10, 20);      // compile error
      test.reset<B, false>(10, 20);
      //any test2(test);            // throw
      any test2;
      //test2 = test;               // throw
      BOOST_CHECK_EQUAL(any_cast<B&>(test).v1, 10);
      BOOST_CHECK_EQUAL(any_cast<B&>(test).v2, 20);
   }
}}}
