Edd Robinson 09da18c08e Add TSM batch key iterator 
The batch focussed TSM key iterator iterates TSM blocks, decoding and
merging blocks where appropriate using the the batch focussed
approaches.

Jason Wilder 16ece490ef Reduce allocation in tsmKeyIterator.Next 
The chunked slice is unnecessary and we can re-use k.blocks throughout
the compaction.

Jason Wilder 4fe81aeee6 Remove manual Gosched from compactions 
At higher cardinalities, this dramatically slows down compaction throughput.

Stuart Carnie eec80692c4 Taught tsm1 storage engine how to read and write uint64 values 
* introduced UnsignedValue type
  * leveraged existing int64 compression algorithms (RLE, Simple 8B)
* tsm and WAL can read and write UnsignedValue
* compaction is aware of UnsignedValue
* unsigned support to model, cursors and write points

NOTE: there is no support to create unsigned points, as the line
protocol has not been modified.

Jason Wilder 2f7d4995b4 Use typed values to avoid allocations 
This switches compactions to use type values (FloatValues) from the
generic Values type.  It avoids a bunch of allocations where each value
much be converted from a specific type to an interface{}.
