conntrack refactor, no behavior changes

- Split connTrackForPacket into 2 functions instead of switching on flag
- Replace hash with struct keys.
- Remove prefixes where possible
- Remove unused connStatus, timeout
- Flatten ConnTrack struct a bit - some intermediate structs had no meaning
  outside of the context of their parent.
- Protect conn.tcb with a mutex
- Remove redundant error checking (e.g. when is pkt.NetworkHeader valid)
- Clarify that HandlePacket and CreateConnFor are the expected entrypoints for
  ConnTrack
