erp5_core&erp5_mysql_innodb_catalog: move MySQL InnoDB SQL methods to erp5_mysql_innodb_catalog

In order to provide other catalog supports than MySQL for erp5

I'd like to make erp5_core independent of catalog because we have SQL methods in erp5_core that are mostly specific to MySQL InnoDB.

Let's move those SQL methods into the erp5_mysql_innodb_catalog bt5 to break this dependency and make it possible for ERP5 to work with different catalog storage.
