Fix bug where having one chunk can cause panic 
When we have only one chunk that is out of range, then we are returning
it unpopulated (w/o calling `Chunk(ref)`). This would cause a panic
downstream.

Fixes: prometheus/prometheus#2629

Fix #59 
Mutating the chunks can change their length. Hence referencing using
previous indices can cause panics.

Make blockQuerier return data in valid time-range 
Fixes #43

Added mint, maxt to chunkSeriesIterator. Adding a field there is
inevitable as something similar is required for ignoring deleted
time-ranges.

Fabian Reinartz e561c91d53 Implement proper buffered iterator 
This adds a proper duration based lookback buffer for series iterators
to allow advancing sequentially while remaining able to calculate time
aggregating functions such as `rate` backwards.

It uses an array ring buffer to minimize heap allocations for
potentially hundreds of thousands of series for a single query.
