Commit Message

Speed up StreamWriter (#825)

Use a goroutine to split up the serial part of writing in StreamWriter to allow another core to work on the table encoding. On my desktop, this can write at the rate of 200MBps (1.6Gbps), finishing 1B keys (16B keys, 16B values) in around 3m20s.

Changes:
* Use a goroutine to split up the serial part of writing in StreamWriter to speed things up.
* Limit to 3 pending requests at a time.
* Use as many goroutines to process requests as the number of streams.
* Update badger.fill tool to send writes to streamwriter concurrently.
* Do batching based on size instead of count.
* Set the value log head correctly.
