Daniel Black 915d951431 MDEV-4827 mysqldump --dump-slave=2 --master-data=2 doesn't record both
Recording both is useful on a replication relay when the backup
can be used to replace the server, or ack as a new replica to the
server.

If an option=2, commented is selected, allow the alternate option
to exist.

This still disables --dump-slave=1 --master-data=1 as having the
a CHANGE MASTER TO and START SLAVE on different positions would be
confusing and dangerious to the try to execute the output. The
previous behaviour of silently disabling --master-data occurs in
this case.

The commented code related to --dump-slave/--master-data is greatly
expanded for human consumption.

A redundant opt_slave_data= 0 was removed from get_opts. If
--dump-slave=1 or 2, then the only possible value of --master-data
is a valid one.

Re-order to preference gtid based replication.

Based of code from Elena Stepanova.
