[2.0] Refactored Doctrine\DBAL\Schema API a bit Table::createColumn() was inconsistent with all the other methods being add*

[2.0] DDC-313 - Removed abstracted trigger support, list functions, list users and the platform specific code to generate the queries for this stuff.

[2.0] DDC-312 -  Refactored View support of all platforms a little - Oracle now also supports the retrieval of the sql used to generate a view so that a common datastructure View is a viable option.

[2.0] DDC-302 - Drop convenience methods since their API is somewhat strange, have to think about something else. Dropped AbstractSchemaManager::listTableConstraints() support - since it only returns the names of all constraints, which are already returned much more nicely with listTableIndexes().

[2.0] DDC-302 - Fix failures occuring from Sqlite Tests in this regard - No test coverage for this features now.

[2.0] DDC-169 - Further refactorings, schema max identifier length is now used for asset generation. Added platform-wide test for unique index generation with create table.

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

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

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

[2.0] DDC-169 - Changed AbstractPlatform and AbstractSchemaManager and children to accept Sequences in their create and get sql methods.

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

[2.0] DC-169 - New method AbstractSchemaManager::createSchema() which creates a schema instance with full tables and sequences, additionally listTables() was rewritten to return a full Table instance instead of just the table names.

[2.0] DDC-169 - Fix build, Postgres, Oracle and Sqlite made some minor troubles with regards to sequences.

[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] Fixed DDC-63 and DDC-106. Oracle tests for SchemaManager need further tweeking, marked as skipped for now.

[2.0] DDC-91 - Enhanced SchemaManager::listTableIndexes() considerably. Add primary keys to the index list, add a bool flag primary to each index, add an array of columns to each index. Moved a test to SchemaFunctionalTestCase to check that every database (Mysql, Pgsql, Sqlite, Oracle) returns exactly the same data from this function.

[2.0] DBAL cleanups (DDC-46). Proxy class improvements (DDC-19, DDC-39). Started new UPGRADE_TO document for upgrade instructions between advancing Doctrine 2 versions.

[2.0] Added functionality to convert a Doctrine 1 schema to Doctrine 2 to help users with upgrading. Lots of other small bug fixes and changes.

[2.0] Introduced SQL logging facilities. Made Type constructor private to prevent instantiation and force use of the factory method getType().

[2.0] More general work on the SchemaManager and Platform classes. Making API more complete and adding sqlite and mysql test coverage.
