Title: [Security][DBAL] Revert MySQL unsigned removal

Revert "Removed MySQL-exclusive usage of unsigned integer from table creation"

This reverts commit 57694aaa94ec0118f516e8962be2f018c36d2011.

The problem is underlying in Doctrine DBAL change tracking and should
either be fixed or ignored there.

I opened a ticket on Doctrine Jira http://doctrine-project.org/jira/browse/DBAL-322
