configuration with HAVE_REPLICATION undefined, which causes the
*_rows_log_event_old classes to only have a default constructor. This
generates an error on some platforms, since the base classes does 
not have a default constructor defined.

Updating signatures of do_prepare_row() for classes above, since
signatures in base classes changed.
