Commit Message

Port Stream framework from Dgraph to Badger (#653)

This PR ports over a Stream framework from Dgraph to Badger. This framework allows users to concurrently iterate over Badger, converting data to key-value lists, which then get sent out serially. In Dgraph we use this framework for shipping snapshots from leader to followers, doing periodic delta merging of updates, moving predicates from one Alpha group to another, and so on.

However, the framework is general enough that it could lie within Badger, and that's what this PR achieves. In addition, the Backup API of Badger now uses this framework to make taking backups faster.

Changes:
* Port Stream from Dgraph to Badger.
* Switch Backup to use the new Stream framework.
* Update godocs.
* Remove a t.Logf data race.
* Self-review
