- Dynamic management of LON-CAPA port 5663 compatible with firewalld
- &get_default_zone(() provides default zone
- Revert changes in rev. 1.17 to &uses_firewalld() -- now returns
1 if firewalld in use, but not the default zone.
- Additional arg, value = 1 if firewalld in use is passed to
&firewall_open_port(), &firewall_close_port(),
&firewall_is_port_open(), &firewall_close_anywhere()
