Ippokratis Pandis 5c4486a2b2 Proper handling of NULL tuples by buffered-tuple-stream. 
Adding a bitstring at the head of each block in the TupleStream that indicates which
tuples of the appended rows in the block are NULLs. When reading the stream, through
GetNext() or GetTupleRow() calls, the NULL tuples are stitched back to their correct
position.

This fixes crashes in PHJ of bushy plans with NULLs on the build side(s) as well as
similar crashes in PAGG and the analytic node.
For example, it fixes IMPALA-1204, IMPALA-1223, and IMPALA-1249.
Also, adds regression tests for IMPALA-1175, IMPALA-1204, IMPALA-1223, IMPALA-1249
and IMPALA-1306.
