-------------------------------------------------+--------------------------
 Patch removes support for comparing differing iterator types from
 ptr_container's void_ptr_iterator. The comparators in question are == != <
 <= > >=.

 Changes are:
 - Add container type template parameter to void_ptr_iterator. This is what
 ensures compared iterators of differing types are still for the same
 referenced container type.

 - Add self type as template argument to base class for containers
 ptr_array, ptr_circular_buffer, ptr_deque, ptr_list, ptr_set,
 ptr_multiset, ptr_unordered_set, ptr_unordered_multiset, and ptr_vector

 - Pass container type template parameter from sequence_config and
 set_config to iterator typedefs, from ptr_sequence_adapter to
 reversible_ptr_container, and from ptr_set_adapter and
 ptr_multiset_adapter through ptr_set_adapter_base to
 associative_ptr_container
