[2.0] DDC-169 - Changed AbstractPlatform and AbstractSchemaManager and children to accept Table, Index and ForeignKey instances for the respective create*() methods.

[2.0] DDC-169 - Converted introspection queries of all platforms to return Column, Sequence, Index, ForeignKey Schema Instances instead of arrays, heavily pimped Oracle support thereby.

[2.0] - DDC-169 - Completed refactoring of SchemaTool::getCreateSql() to use new DBAL Schema API, several internal optimizations in SchemaTool are now possible. Stripped out shared functionality with getUpdateSql() so that this part of SchemaTool is still completly working with the old API.

[2.0][DDC-164][DDC-165] Fixed. Cleaned up ManyToManyMapping. Cleaned up identifier handling and handling of composite identifiers in some places.

DDC-126 - Make Query, NativeQuery Fluent-Interfaces for all their set Methods, renamed setExpireQueryCache() and setExpireResultCache() to expireQueryCache() and expireResultCache(). Updated UPGRADE_TO_2_0 document accordingly.

DDC-127 - Enhance IterableResult by making it implement the Iterator interface, wrote a unit-test for this scenario, also added some additional tests for special cases in the query api that lead to exceptions.

[2.0][DDC-158] Fixed. Collections did not take snapshots after lazy initialization leading to wrong change sets.

[2.0] Fix Tab Formating in ParserResult class, added doc-comments and fixed a missing variable initialization error for certain query special cases.

[2.0] DDC-115 - Proper fix of global namespace problem was in the ClassMetadataInfo, a namespace plus seperator was appended for reasons of shortcuts. However this broke associations in global namespace. Changes to ClassMetadataFactory were reverted and fix plus tests applied to ClassMetadataInfo.

[2.0] DDC-115 - Fix for multiple class metadata instances because of classes being addressed with or without prepending namespace separator.

[2.0] More refactorings in Annotations parser and DQL parser. Now they only use constants instead of string processment

[2.0] DDC-84 - Added increment alter table / update schema tests for Oracle Platform - Fixed a simple bug in Postgres Tests.

[2.0] DDC-84 - Added increment alter table / update schema tests for Postgres Platform - Fixed several bugs in Doctrine\DBAL\Platforms\PostgreSqlPlatform

[2.0] Fixed DDC-101, DDC-102 - Ensure defaults for string length and field nullability are handled consistently in both update and create schema commands of SchemaTool.

[2.0] DDC-84 - Add Mysql Platform unittests for incremental changes of the metadata for the schematool update function. Fixed some quirks in the Unit-Test suite alongside, Fixed changes of length in SchemaTool update.

[2.0][DDC-22] Fixed. Also cleaned up association handling. More to come: exception refactorings, proxy simplifications (single proxy class, not two).
