Zheng Shao updated HIVE-136:
----------------------------

    Description: 
MetadataTypedColumnsetSerDe and DynamicSerDe should escape some special characters like '\n' or the column/item/key separator.
Otherwise the data will look corrupted.

We plan to deprecate MetadataTypedColumnsetSerDe and DynamicSerDe for the simple delimited format, and use LazySimpleSerDe instead.
So LazySimpleSerDe needs to have the capability of escaping and unescaping.
