Unnest Positional Type Is A Constant

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Use VXQuery. See issue #115. 
https://issues.apache.org/jira/browse/VXQUERY-115
2. Basically any system that does not represent INT32 typed variable with the 
tag value of 3.
3.

What is the expected output? What do you see instead?

The system should use the UNNEST position variable type specified when creating 
an UNNEST or provide another method to set this type value. Currently the type 
is hard coded to 3, presumably for AsterixDB.

Side note: Is an int the best size for this value? Long?

// Problem code
if (hasPositionalVariable) {
  // Write the positional variable as an INT32
  tupleBuilder.getDataOutput().writeByte(3);
  tupleBuilder.getDataOutput().writeInt(offset + positionIndex++);
  tupleBuilder.addFieldEndOffset();
}

Please use labels and text to provide additional information.

The new interface has been committed and new supports new position writer.
