- associated properties of the completion handler are correctly propagated.
Removed buffer from packet interface except the infterface for adcanced user. #195, #262
- For example, create PUBLISH packet using "topic1", and get the filed as string by topic().
  - No allocate_buffer("topic1") is required.

2.0.0

breaking changes

endpoint

Made endpoint non movable. #79.
- It is designed non copyable and non movable but the code was able to movable invalidly, so this is a bug fix. However some of test, broker, and bench code had been used move constructor. Hence I categolize the fix to breaking changes.
