memory: Add Error** argument to .log_global_start() handler
Modify all .log_global_start() handlers to take an Error** parameter and return a bool. Adapt memory_global_dirty_log_start() to interrupt on the first error the loop on handlers. In such case, a rollback is performed to stop dirty logging on all listeners where it was previously enabled.
