C++11 allocator support for std::list.

        PR libstdc++/55409
        * include/bits/list.tcc (_List_base::_M_clear()): Use allocator traits.
        (list::list(const list&)): Use allocator propagation trait. Use
        _M_assign_dispatch to copy elements.
        * include/bits/stl_list.h (_List_node): Use __aligned_membuf in C++11.
        (_List_node::_M_valptr()): Add accessor for stored value.
        (_List_iterator, _List_const_iterator, _List_base): Use _M_valptr().
        (_List_base, list): Use allocator traits.
        (_List_base::_M_get_Tp_allocator, _List_base::get_allocator): Remove.
        (_List_base::_M_move_nodes): New function.
        (_List_base(_List_base&&)): Use _M_move_nodes.
        (_List_base(_List_base&&, _Node_alloc_type&&)): New constructor.
        (list::_M_create_node, list::_M_erase, list::max_size): Use allocator
        traits.
        (list(size_type)): Add allocator parameter.
        (list(const list&)): Use allocator propagation trait.
        (list(const list&, const allocator_type&)): New constructor.
        (list(list&&, const allocator_type&)): Likewise.
        (list::operator=(list&&), list::swap(list&)): Use allocator
        propagation traits.
        (list::_M_move_assign): New functions.
        * include/debug/list: Add allocator-extended constructors.
        * include/profile/list: Likewise.
        * python/libstdcxx/v6/printers.py (get_value_from_list_node): New
        function to get value from _List_node.
        (StdListPrinter): Use get_value_from_list_node.
        * testsuite/23_containers/list/allocator/copy.cc: New.
        * testsuite/23_containers/list/allocator/copy_assign.cc: New.
        * testsuite/23_containers/list/allocator/minimal.cc: New.

        * testsuite/23_containers/list/allocator/noexcept.cc: New.
        * testsuite/23_containers/list/allocator/swap.cc: New.
        * testsuite/23_containers/list/requirements/dr438/assign_neg.cc:
        Adjust dg-prune-output line number.
        * testsuite/23_containers/list/requirements/dr438/constructor_1_neg.cc:
        Likewise.
        * testsuite/23_containers/list/requirements/dr438/insert_neg.cc:
        Likewise.
