Hello Taras Bobrovytsky, Dan Hecht,

I'd like you to reexamine a change.  Please visit

to look at the new patch set (#7).

IMPALA-3729: batch_size=1 coverage for avro scanner

Also fix a stale comment in the avro scanner header.

The main work here is to fix the handling of empty result sets in the
test result verifier. This is a problem because we wanted to verify
that the results in the test file were a superset of the rows
returned, and this was thrown off by superflous '' rows in the expected
and actual result sets.

The basic problem is that the way test file sections
was parsed conflated an empty result section with non-empty result
section that had a single empty string. I.e.:

---- RESULTS
====

vs
---- RESULTS

====

both got resolved to [''].
