bcc56859af Add a unit test to check before/after processing by the dummy timestamper.
Tweak the timestamping API a bit.

784452ac50 Reorganise how time is handled: timestamping authorities are now oracles who sign the entire transaction.
As a result, TimestampedWireTransaction is gone. Timestamp fields are gone. Timestamp commands contain before/after fields. The notion of time tolerance is now a part of the timestamping interface and timestamp data.

TODO:
- Unit tests to verify the notBefore/notAfter logic
- Documentation update

6144ccc2c7 Small cleanup of commands.
1. Rename Command -> CommandData, WireCommand -> Command, PartialTransaction.addArg -> addCommand
2. Add some helper functions to PartialTransaction to make creation of transactions simpler.

65c5fa7502 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.

7881be07ed 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.

73cbd41a09 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.
