Clean up BufferHubQueue API and internal bookkeeping.
- Simplify buffer hangup accounting.
- Add extra checks to gracefully handle the epoll set and slots array
being out of sync.
- Add tests for detaching buffers.
- Switch to using Status<T> for all return/error values.
- Fix minor bug in BufferHubQueueProducer from earlier Status<T>
return value change.
