Improves memaslap UDP posix throughput on my laptop by 40% (from 73k to 105k). When item is created we cache flags and size part of the response so that there's no need to call expensive string formatting in get(). The down side is that this pollutes "item" object with protocol-specific field, but since ASCII is the only protocol which is supported now and it's not like we can't fix it later, I think it's fine.
