Migrate updatelog to abstract schema

And fixing the schema drift between mysql and postgres in this table by
changing field type of ul_key and ul_value from TEXT and TEXT to
VARCHAR(255) and BYTEA respectively.

The automatic generation is done with running generateSchemaSql.php
maintenance script. More info:
