lots of tests failing on MS SQL Server due to reserved keyword usage

Lots of tests in Hibernate TS are using identifiers which are reserved keywords on MS SQL Server.
For example, most tests in org.hibernate.test.collection.* package, org.hibernate.test.annotations.query.QueryAndSQLTest, org.hibernate.test.annotations.entity.BasicHibernateAnnotationsTest,...

• ComponentTest: Invalid column name 'username'.
