1. Breaks up functionality within `ProcState` into several other structs to break out the responsibilities (`ProcState` is only a data struct now). 2. Moves towards being able to inject dependencies more easily and have functionality only require what it needs. 3. Exposes `Arc<T>` around the "service structs" instead of it being embedded within them. The idea behind embedding them was to reduce the verbosity of needing to pass around `Arc<...>`, but I don't think it was exactly working and as we move more of these structs to be more injectable I don't think the extra verbosity will be a big deal.
