The fix is already in master at
https://github.com/doctrine/dbal/commit/387eb5457498781e24716286a2511f5d030d63fb
but because it has not been backported the functionnality is still broken
for symfony 2.5 for instance.

- Fixed docblocks
- Removed return statements on void methods
- Cleaned up unused private / local variables
- Fixed license issues
- Removed SVN leftovers
- Fixed doctrine-project.org links
- Added line breaks before return statements
