-----------------------------------

Reviewed last patch on RB.  Everything looks good except for a change in the handling of [T1,Tn,NULL] types.

> Currently, the AvroSerde recursively copies all fields of a record from the GenericRecord to a List row object and provides the standard ObjectInspectors. Performance can be improved by providing ObjectInspectors to the Avro record itself.
