Description

Define new core interfaces and classes, stealing where appropriate from current trunk.

Interfaces and classes considered "core:"

• Event, event builder
• Source / sink interfaces, abstract classes, and registries
• Lifecycle support interfaces and classes
• Trivial sources and sinks with NO external dependencies beyond what Flume itself needs (i.e. NullSink, LoggerSink, SequenceGeneratorSource).
