c6fdffd932 firewall (#7355) - partially revert r21486, start firewall on init again - skip iface hotplug events if base fw is not up yet - get ifname and up state with uci_get_state() in iface setup since the values gathered by scan_interfaces() may be outdated when iface coldplugging happens (observed with pptp) - ignore up state when bringing down interfaces because ifdown reverts state vars before dispatching the iface event - bump package revision

de15765a37 firewall: - defer firewall start until the first interface is brought up by hotplug, fixes race conditions on slow devices - create a file lock during firewall start and wait for it in hotplug events, prevents race conditions between start and addif - start firewall actions in background from hotplug handler since the firewall itself fires further hotplug events which results in a deadlock if not forked off - get loaded state direcly from the uci binary since updated value is not recognized by config_get after uci_set_state - bump package revision to r2
