Review request for hive and Prasanth_J.

Bugs: HIVE-17611

Repository: hive-git


Create new LazyBinarySerDe2 class which derives from LazyBinarySerDe.
Avoid the ObjectInspector getCategory()/getPrimitiveCategory() calls for every row/column
by making those calls during initialization and creating serialization objects for each column.
Then serialization of the row is just a matter of calling serialize() on these pre-initialized
