Fix for SQOOP-1097
Review Request #12342 - Created July 8, 2013 and updated
Fix for mysql export using procedure. While fixing this, found that Oracle export also has additional issues when using DB specific types that are not handled. Fixed both the issues and provided a generic implementation for future db tests.
All unit tests pass. Created a mysql and oracle specific test for testing both the functionality of doing procedure based export and handling db specific types
