Tim Armstrong 081ecf0152 IMPALA-5618: buffered-tuple-stream-v2 fixes ...

This fixes two issues:
* AddRowCustom() caused a performance regression when the function
  was heap-allocated. This is solved by splitting the API into two
  separate calls. This imposes an additional burden on the caller
  but it is easier to reason about its performance.
* Allow re-reading streams with 'delete_on_read_' set so long as no rows
  were read from the stream. This is necessary for some spilling ExecNodes
  that prepare the stream for reading in order to acquire the buffer,
  but then need to spill the stream to free memory before they actually
  are able to read the stream.
