Problem - The default port number shown in SHOW SLAVE HOSTS is always 3306
though the slave is actually listening on a different port number.
This is a problem as the user can not be sure whether this port
value can be trusted and so client trying to read replication
topology can get confused.
Fix - 3306 ceases to be the default value of report-port. Moreover report-port
does not have a static default any longer.
Instead we initialize report-port to 0 as the new default value and change
it based on two checks :
1) If report_port is not set, the slave reports the port number its listening
on. (i.e. if report-port is not set we get the actual value of the slave's
port number).
2) If report-port is set, we show the value report-port is set to, as the slave's
port number.
