Add protocol versions to {Worker,Serve}Proto::*Conn

Browse source 
This will allow us to factor out logic, which is currently scattered
inline, into several reusable instances

The tests are also updated to support versioning. Currently all Worker
and Serve protocol tests are using the minimum version, since no
version-specific serialisers have been created yet. But in subsequent
commits when that changes, we will test individual versions to ensure
complete coverage.
