(_Hashtable<>::_M_before_begin): Rename into _M_bbegin and type
modified to __detail::_Before_begin<>.
(_Hashtable<>::_M_node_allocator()): New, get the node allocator
part of _M_bbegin.
(_Hashtable<>::_M_before_begin()): New, get the before begin node
part of _M_bbegin.
(_Hashtable<>): Adapt to use latter.
