Jo-Philipp Wich 36a417a05f [package] 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	  since the values gathered by scan_interfaces() may be outdated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

Jo-Philipp Wich fa11019822 [package] 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
