The 'server' library has always been a catch-all and ideally only the hub links it in (far future goal). In line with this I move a list of files out of server into the utils lib. I choose 'utils' because all these are plain old data objects that many crypto apps will find useful. now in utils/primitives/ * CScript * CPubKey * CTransaction * CBlock * FastTransaction * FastBlock * CScript streams.h is now in utils/streaming/ hash.h is now in utils/
