(For those who don't want to look through git and the history: the
problem is that making the builds use old and new means you can build
client and server with different proto versions and not even notice.
That makes debugging all the harder because everything seems to be ok
but you're now taking untested paths on the client and/or server side
due to #ifdefs and protocol mismatches.)
