These changes are largely useless, because most of them are simply
allowing 'reference' and 'const_reference' types to be obtained from an
allocator, and since C++11 allocators don't define reference types (they
just use plain lvalue references. Pretending to support C++98 allocators
with user-defined reference types is a waste of time (especially as
several of the pb_ds types appear to use a static allocator object which
means stateful allocators are not supported).
