[2.0][DDC-171] Fixed (second attempt). Some other cleanups. Performance fix for mock Statement used in hydration performance tests for more accurate and better results.

[2.0] DDC-176 - Disallow iterate() over fetch-join collections by the means of an exception on parsing the DQL query.

[2.0] DDC-194 - Fixed infinite recursion issue with references and @PostLoad annotation by telling proxy to be loaded before calling EntityPersister->load...

[2.0] DDC-168 - Add test-case that proves that the order of reflFields matters for inserting, which causes problems with caching.

[2.0] Fixed more STRICT standards notices (only variables should be passed by reference...). @beberlei, error_reporting=E_ALL | E_STRICT

[2.0] Fixed PHP Notice in SchemaTest (only variables should be passed by reference...) and a few other cosmetics in various parts.

[2.0] DDC-197 - Extended CLOB Test-Case even more with additional update of the string, which still works on OCI8

[2.0] DDC-197 - Fix for OCI8 returning CLOBs as OCI-LOB instances, was it that easy? The test suggets that inserting clobs is not even requiring the temporary syntax anymore.. Great!

[2.0] DDC-169 - Finished ALTER Table TableDiff refactoring, adding code to handle index and FK changes. Added a general functional test for alter table against all platforms.

[2.0] DDC-169 - AbstractPlatform::getAlterTableSql() now accepts only a TableDiff instance as argument across all platforms.

[2.0] DDC-169 - Add functionality to detect that an add + drop column diff is actually just a rename column.

[2.0] DDC-169 - Stripped case handling since its just a load of complex crap and doesn't solve any problem! Idea: just implement case-insensitivity in the comparator.

[2.0] DDC-169 - Added possibility to control which case mode schema assets are created with in SchemaManager

[2.0] DDC-186 - Fixed DatabaseDriver to work with new Schema abstraction, added functional test-cases for database to yaml convertion.

[2.0] DDC-186 - Fixed SchemaTool indexes behaviour, changed a functional/integration model to use one index for test-coverage.

[2.0] DDC-191 - Added test that verifies mixed case identifier generation is default, when no case mode is set due to previous commit for DDC-169 ticket.

[2.0] DDC-169 - Introduced handling of schema / database case-sensitivity differences and to allow compability between different platforms.
