- Remove as many IGNITE_ parameters as possible from IgniteSystemProperties.
- Remove deprecated methods, fields and classes marked with `@deprecated`.
- Make 'pairedConnections' on by default in TcpCommunicationSpi?
- Implement new BinaryObject with field type changes and constant-time access to constant-length fields.
