Fix NH-2840 - SetFirstResult and SetMaxResults do not work correctly on Oracle (ODP.NET) (re-applied with corrected line endings)

Fixes the following tests on Oracle:

NHibernate.Test.Criteria.CriteriaQueryTest.SimplePagination
NHibernate.Test.Criteria.Lambda.IntegrationFixture.RowCount
NHibernate.Test.Legacy.FooBarTest.Limit
NHibernate.Test.Legacy.FooBarTest.PSCache
NHibernate.Test.Legacy.SQLFunctionsTest.SQLFunctions
NHibernate.Test.NHSpecificTest.NH1533.Fixture.Can_query_using_two_orderby_and_limit_altogether
NHibernate.Test.NHSpecificTest.NH2251.Fixture.FuturePagedHql
NHibernate.Test.NHSpecificTest.NH2251.Fixture.HqlWithOffsetAndLimit
NHibernate.Test.NHSpecificTest.NH2251.Fixture.MultiplePagingParametersInSingleQuery
NHibernate.Test.Pagination.PaginationFixture.PagTest
NHibernate.Test.QueryTest.DetachedQueryFixture.ExecutableQuery
