Bug #44663 Unused replication options prevent server from starting.

Description:
There are some options that if set, prevent the server from starting, because they depend on other options that are not set. For example, "log-slave-updates", depends on "log-bin". Searching in mysqld.cc I find:

  if (opt_log_slave_updates && !opt_bin_log)
  {
    sql_print_error("You need to use --log-bin to make "
                    "--log-slave-updates work.");
    unireg_abort(1);
  }

The same happens with "binlog-format" which prevents the server from starting if "log-bin" is not set. However, this was already reported in BUG#42928.

How to repeat:
Inspect the code, or start server with --log-slave-updates without --log-bin enabled.

Suggested fix:
Maybe, printout a warning instead of an error and let the server proceed with startup.

Thank you for the report.

Verified as described.

Pushed into 5.4.4-alpha (revid:anozdrin@bk-internal.mysql.com-20090710111017-bnh2cau84ug1hvei) (version source revid:alfranio.correia@sun.com-20090709225859-kri2kkweytz6zex0) (merge vers: 5.4.4-alpha) (pib:11)

Documented bugfix in the 5.4.4 changelog as follows:

        The server failed to start when using the --log_slave_updates
        option without also using the --log_bin option. Now in such
        cases, only a warning message is generated.

Noted in 5.4.2 changelog because next 5.4 version will be 5.4.2 and not 5.4.4.

Ignore previous comment about 5.4.2.
