Do not reload twice carp and vips in general during an interface reload.

Correct code to reconfigure an interface for groups/gre/gif tunnels to take into account that an interface might be part of many instances of this. Also reconfigure interface groups for every newwanip trigger on interfaces to make sure dynamic interfaces retain their membership on groups.

Ticket #491. Do not actually check for enable to exist but for host since enable might be unset explicitly by the user. This should re-enable configs to work.

Ticket #1073. Gray out the rules when they are disabled.

Use send_event since touch()'ing files does not work.

Do not call filter_configure here the caller does. Also remove old code of the times when check_reload_status used files as trigers.

The caller of this function is responsible for this and usually all the callers do this from what i can tell. Remove redundant call.

Make sure filter_configure() is not called during bootup since its harmful.

Do not spam filter reload at boot.

No need to call filter_reload from here.
