Tim Armstrong bc8c55afcd 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 [''].
