This reverts commit c4628a0b.
It looks like pkg can't handle php70 to php71 at all.

filter, rule generation. don't wrap aliases in curly brackets, it seems to crash when a to port is written like {$portalias}

We added the former, but it basically says the same thing.  ;)

firewall, plugin. Add schedules back again, move state kill to end of processing and out of the rule registration.

firewall, plugin. move filter_generate_ipsec_rules() out of the way, move to plugin type rules later.

firewall, plugin. start moving user generated rules into the same logic as the plugins. step by step.

First enable our gateways and gatewaygroups on our plugin system and setup reply-to attributes in interface metadata (could be temporary, but good enough for now)

firewall / plugin, add getInterfaceGateways() and additional metadata to fetch all related gateways. Needed for some of the current internal rules.
