* Robust startup: if iptables module gets fully initialized after
startup of fail2ban, fail2ban will do "maxreinit" attempts to
initialize its own firewall. It will sleep between attempts for
"polltime" number of seconds (closes: #334272).
* To overcome possible conflict with other firewall solutions and as a
secondary solution for the bug 334272, fail2ban startup is moved
during bootup to the latest (S99) sequenece position. That should not
cause any discomfort I believe.
