8802	Add is_copy_constructible<T> trait	Antony Polukhin	Antony Polukhin	"Add an implementation of `is_copy_constructible<T>` trait. It must work with C++11 and in C++03 it must detect constructors assuming that if type is derived from `boost::noncopyable` or uses BOOST_MOVABLE_BUT_NOT_COPYABLE macro - it has no copy constructor.

Boost.Move requires the following patch applied to to BOOST_MOVE_IMPL_NO_COPY_CTOR_OR_ASSIGN in boost/move/core.hpp :
{{{
#ifdef BOOST_NO_CXX11_DELETED_FUNCTIONS
   #define BOOST_MOVE_IMPL_NO_COPY_CTOR_OR_ASSIGN(TYPE) \
      private:\
      TYPE(TYPE &);\
      TYPE& operator=(TYPE &);\
+      public: \
+      typedef int boost_move_no_copy_constructor_or_assign; \
+      private: \
   //
#else
