Add Stream Batching Buffer (#916)

Browse source 
The difference between a stream buffer and a stream batching buffer is when
a task performs read on a non-empty buffer:
- The task reading from a non-empty stream buffer returns immediately
   regardless of the amount of data in the buffer.
- The task reading from a non-empty steam batching buffer blocks until the
   amount of data in the buffer exceeds the trigger level or the block time
   expires.
