Description:
add boltdb implement for db interface.
The boltdb is safe and high performence embedded KV database. It is based on B+tree and Mmap.
Now it is maintained by etcd-io org. https://github.com/etcd-io/bbolt
It is much better than LSM tree (levelDB) when RANDOM and SCAN read.
Replaced #3604
Refs #1835

* some modifies
* address my own comments
* fix most of the Iterator tests for boltdb
* bolt does not support concurrent writes while iterating
* add WARNING word
