In 2.5 we added the ability to set per-pool default query
options. A string of key-value pairs can be specified with a
pool configuration. However, if any options fail to parse,
then all the options are ignored. We want that behavior (and
returning an error) when parsing the process-wide default
query options on startup and when parsing the options sent
from a client (e.g. in beeswax server) because an error can
be returned immediately for the triggering action at that
time (i.e. starting the impalad or submitting a query with
the options set). This behavior is bad for the pool default
query options because (a) the configuration is set by the
administrator and there's nothing we can do until a query is
submitted and (b) one invalid option shouldn't mean that
other valid options aren't set.

This change fixes two problems:
1. The query options OPTIMIZE_PARTITION_KEY_SCANS and
DISABLE_STREAMING_PREAGGREGATIONS are both boolean
so they should accept 'true' and '1' as input values.
Previously, these two options are treated as int and
value such as 'true' doesn't work with them.
2. The break statement in the case statement of the option
SCAN_NODE_CODEGEN_THRESHOLD was 'stolen' by the option
DISABLE_STREAMING_PREAGGREGATIONS when it was added.
This change adds the missing break statement back for
SCAN_NODE_CODEGEN_THRESHOLD.

A failed test case inside a test file will leave the rest of
the test cases in the file unexecuted. Some test cases may
modify some query options such as memory limit and then
restore them in the subsequent test cases in the same file.
The failure of those test cases will leave the query options
modified, causing cascading failures to other test cases
which aren't expected to be run with the modified query
options (e.g. lowered memory limit). This problem may lead
to broken builds which are recorded in IMPALA-2724 and
IMPALA-2824.
This change fixes the problem above by checking if a test
case modifies any query option and if so, restore those
modified query options to their default values. This change
makes the assumption that a test should not modify an option
specified in its test vector so it's safe to restore the
modified query options to their default values.

This patch makes the ownership of the memory backing the tuple pointers of
a RowBatch dependent on whether the legacy joins and aggs are enabled:
By default, the memory is malloc'd and owned by the RowBatch:
If enable_partitioned_hash_join=true and enable_partitioned_aggregation=true
then the memory is owned by the RowBatch and is freed upon its destruction.
This mode is more performant especially with SubplanNodes in the ExecNode tree
because the tuple pointers are not transferred and do not have to be re-created
in every Reset().
Memory is allocated from MemPool:
Otherwise, the memory is allocated from the RowBatch's tuple pool. As a result,
the pointer memory is transferred just like tuple data, and must be re-created
in Reset(). This mode is required for the legacy join and agg which rely on the
tuple pointers being allocated from the RowBatch's tuple pool, so they can
acquire ownership of the tuple pointers.
Performance impact for nested types:
Initial cluster runs and profiling on nested TPCH identified excessive
malloc/frees as a major performance bottleneck. This change paves the way
for further optimizations which yielded a 2x improvement in response time
for most nested TPCH queries.

The value of PARQUET_FILE_SIZE overflows when RoundUp() is called because this function
returns an int32. Even with this change, this value will still overflow when calling the
HDFS API since it is passed to hdfsOpenFile() as blocksize, which is an int32 parameter
(see HDFS-8949).
Changes:
- Return an error if PARQUET_FILE_SIZE is set to a value greater than or equal to 2GB.
- If PARQUET_FILE_SIZE is set in an Impala session to a value greater than or equal to
2GB, then every query will fail with an error message.
- If PARQUET_FILE_SIZE is changed to a value greater than or equal to 2GB as an impalad
argument, impalad will not start and log an error.
- Ceil(), RoundUp(), RoundDown() return int64.

Our .test file parser used to not abort tests when there
is a malformed test/section. This patch changes that behavior
to report an error and treat the test as failed.
Quite a few tests were not well-formed, and were not executed
as a result. This patch fixes those tests.
Arguably, the test file parser should be more flexible in which places
to accept comments, but this patch does not address that problem.

This supports both uncompressed and block compressed formats. Row compressed formats are
not supported. The type of compression is specified using a query parameter
COMPRESSION_CODEC with values NONE, GZIP, BZIP2, and SNAPPY.
Note: this patch only has basic testing. More extensive testing will be done when this
avro writer is used in data loading.

Also add support for "SET", which returns a table of query options and
their respective values.
The front-end parses the option into a (key, value) pair and then the
existing backend logic is used to set the option, or return the result
sets.
