	* bits/cpp_type_traits.h: Changed __is_pod completely. Now, it
	does not use any of the previous type_traits to detect the pod
	types, and it also detects function pointers as POD types.

	* bits/stl_tree.h: Introduced a new class _Rb_tree_impl, which
	encapsulates the internal implementation of an rb_tree. Made
	the allocator a base class of this class instead of the
	rb_tree, which was not conforming. This _Rb_tree_impl class is
	also specialized on whether the _Compare parameter is a POD
	type or not. If so, then it maintains the comparison function
	as a data member, otherwise it makes the _Compare parameter a
	base class of itself. Also, _M_key_compare is now a function
	instead of a data member, so that the above trick can work
	properly. Delegated the initialization of the other data members to
	this newly created class. Also, now other member functions of rb_tree
	must refer to _M_key_compare as _M_impl._M_key_compare(). The
	other data members (*) can be referenced to as _M_impl.(*), where
	(*) includes _M_header, and _M_node_count.

	* bits/stl_list.h: Created a _List_impl class and made it
	derive from the allocator, instead of the list deriving from the
	allocator class, which was not conformant. Changed all references
	from this->_M_node to this->_M_impl._M_node

	* bits/list.tcc: Same as above (changed all references to
	the concerned variables).

	* bits/stl_deque.h: Created a _Deque_impl class and made it
	derive from the allocator, instead of the deque deriving from the
	allocator class, which was not conformant. Changed all references
	to the _M_start, _M_finish, _M_map, and _M_map_size to
	_M_impl.*.
	(_Deque_base<_Tp,_Alloc>::~_Deque_base()): Added this->
	qualification in 2 places where it was missing.
	(_Deque_base<_Tp,_Alloc>::_M_initialize_map(size_t)): Same as
	above.

	* bits/deque.tcc: Same as above (changed all references to
	the concerned variables).

	* bits/stl_vector.h: Created a _Vector_impl class and made it
	derive from the allocator, instead of the _Vector_base class,
	deriving from the allocator which was not conformant. Changed
	all references to the _M_start, _M_finish, and
	_M_end_of_storage to _M_impl.*.

	* bits/vector.tcc: Same as above (changed all references to
	the concerned variables).
