Messaging: (mock) in memory network implementation improvements.
...
- Now supports simulated restart of nodes
- Messages sent to non-running nodes are queued for delivery
- Messages received by a node that don't match any topics are queued until handlers are registered
These improvements help us unit test various robustness features and ensure things work in truly concurrent context where there can be race conditions like receiving a message before the node had a chance to register the right handlers.

First draft of a basic messaging module interface (VERY ROUGH). Ideally, is something that can have an e.g. Kafka backend, with a full P2P implementation later.

Delete a lot of Kryo/serialisation related boilerplate.
...
This is/was an attempt to be secure against malicious streams, but as Kryo is just a temporary bit of scaffolding and isn't intended to be actually used in any real product, it was just a waste of time and the registration requirement was getting increasingly awkward.

Misc fixes:
...
- Use the OpaqueBytes wrapper (a box for byte[]) inside TimestampedWireTransaction to avoid array comparison issues.
- Introduce a few utility functions to make OpaqueBytes less painful.
- Make StateAndRef serialisable
- Introduce the notion of an OwnedState which abstracts out the owner field.
