- Where agg_func is a SQL/SQL++ aggregate function

- Fix percent_rank() to always return 0 for the first tuple

- Fix ntile() to handle NULL argument

[ASTERIXDB-2286][COMP][FUN][HYR] Parallel Sort Optimization

- user model changes: yes

- storage format changes: no

- interface changes: yes

details:

- new plan for sort operation which includes sampling and

replicating the stream of data to be sorted. Sort-merge connector

is removed from the plan. The sorted result now is in multiple partitions.

- new optimization rule to check whether full parallel sort is applicable.

- new Forward operator to read the replicated sort input stream and

to receive the ouput of the sampling.

- new sequential merge connector to merge a globally ordered result residing

in multiple partitions (in addition to the connector's partition computer).

- "asterix-lang-aql/pom.xml" is changed as a result of refactoring

code related to the range map handling.

- new private sampling function to generate the range map object

(local & global functions) & their type computers.

user model changes:

- new compiler property is added to enable and disable parallel sort.

interface changes:

- "ILogicalOperatorVisitor.java" includes Forward Operator.

- "ITuplePartitionComputer.java" includes initialize() to enable partitioner

to do some initialization. FieldRangePartitionComputerFactory uses it to

pick a range map.

- "ITuplePartitionComputerFactory.java". createPartitioner() is changed to

createPartitioner(IHyracksTaskContext hyracksTaskContext). Context is needed

for transferring the range map throught the context.
