Refactor the message distribution process

To solve a major problem: when there are many devices connected,
the broker will blocked in processing messages.

By the way, I've rewritten and reorganized the entire code architecture,
improved performance.

Some new features has been added:
* support device grouping.
* support show device's IP address.
