CONC-592: Register replica with host and port

Browse Source 
Added new option MARIADB_OPT_RPL_REGISTER_REPLICA which expects
two parameters, host and port. When this option was set, rpl_open
will send a COM_REGISTER_SLAVE command with server_id, host and
port to the connected server. This information can be retrieved
by "SHOW SLAVE STATUS" command.

Example:

rc= mysql_optionsv(mysql, MARIADB_OPT_RPL_REGISTER_REPLICA,
                   "myhost", 123);
