OPNsense opnsense: /interfaces_vlan_edit.php: The command `/sbin/ifconfig 'em2_vlan1' vlandev 'em2' vlan '1' vlanpcp '0'' failed to execute
OPNsense opnsense: /interfaces_vlan_edit.php: The command '/usr/sbin/ngctl name 'vlan1': 'em2_vlan2'' returned exit code '71', the output was 'ngctl: send msg: No such file or directory'

interface_bring_down() doesn't use a real interface name as call argument, mwexecf('/usr/sbin/ngctl name %s: %s', array($tmpvlanif, $vlanif)) isn't used by my knowledge.

firewall_rules, keep category selection when changing tabs. closes https://github.com/opnsense/core/issues/1592

guiconfig.inc, add class to top_tab so we can find them easier, for https://github.com/opnsense/core/issues/1592

* Plug gateway fixup "feature" into filter_configure_sync(), the
  only point where it should matter as everything else is GUI
  trigger-happy disruption.

* Discourage the use of the "feature" by moving it into the firewall
  advanced settings, adding a deprecated note.

* Use the new system_default_route() call to avoid code drift.

As a side-note, IPv6 gateway switching is really discouraged,
especially with auto-address configuration techniques...

Discussed with: @adschellevis

filter, add "reply-to" to plugin model, disabled by default for bootstrapped rules. needs gateway/gatewayv6 registered in filter.inc before it can actually function.

filter plugin, work in progress. add systemDefaults to plugin and add disablereplyto tag in there, so we can set this tag globally without having to link the config in the filter parsing logic.
This shouldn't hurt our current deployment, it's needed to add "reply-to" parsing in the rule class.

missed the pfctl counters in www/widgets/api/plugins/interfaces.inc, for https://github.com/opnsense/core/issues/1662

regression, missing ipv4 address in get_interfaces_info(), for https://github.com/opnsense/core/issues/1662
