to be able to make OCI8 derived classes

DDC-515 - Enhanced Validate-Schema-Command, integrated it with CLI and besides mapping<->database checks also do consistency checks of the mapping files

Removed EntityTransaction until it has a real purpose. Added the affected entity to OptimisticLockException. Updated functional optimistic locking tests accordingly.

Revertd partially the support to DBAL\Transaction, it was wrong. Fixed implementation of ORM\EntityTransaction and fixed tests.

Fixed svn dependency in build file and some weird issues where the oci8 driver loses spaces in the sql while transforming positional to named parameters.

Fixed pecl/ibm_db2 Driver and Connection to run smoothly against the complete test-suite (depending on a c-patch to the extension though)

DDC-496 Finished first versions of platform and schema manager for DB2, DDC-528 Added support for PDO_IBM driver, passing all but 3 tests that are related to CLOB fields

[2.0][DDC-354][DDC-425] Fixed. Encapsulated SQL logging better in the DBAL. Added binding types to DBAL mapping types as well as using these binding types in the persisters. Query and NativeQuery now support PDO binding types as well as DBAL mapping types when binding parameters.

[2.0] DDC-321, DDC-323, DDC-324 - Implemented way to define UDFs from PHP in Sqlite Driver and registered to required default callbacks for SQRT and MOD, allowing functional tests for DQL MOD and SQRT to pass for all platforms.
