f30ccc8991 firewall: allow DHCPv6 traffic to/from fc00::/6 instead of fe80::/10
There is no RFC requirement that DHCPv6 servers must reply with a link local
address and some ISP servers in the wild appear to using addresses in the ULA
range to send DHCPv6 offers.

d534883a52 firewall: Allow IGMP and MLD input on WAN
The WAN port should at least respond to IGMP and MLD queries as
otherwise a snooping bridge/switch might drop traffic.

RFC4890 recommends to leave IGMP and MLD unfiltered as they are always
link-scoped anyways.

2ae05c57f8 package/*: remove useless explicit set of function returncode
somebody started to set a function returncode in the validation
stuff and everybody copies it, e.g.

myfunction()
{
	fire_command

	return $?
}

a function automatically returns with the last returncode,
so we can safely remove the command 'return $?'. reference:

http://tldp.org/LDP/abs/html/exit-status.html
"The last command executed in the function or script determines the exit status."

bb699867e0 firewall: Improve ubus support
* Use network.interface dump call instead of individual status calls
  to reduce overall netifd lookups and invokes to 1 per fw3 process.

* Allow protocol handlers to assign a firewall zone for an interface
  in the data section to allow for dynamic firewall zone assignment.

e106f25ee7 firewall: various enhancements
- reduce mssfix related log spam (#10681)
	- separate src and dest terminal chains (#11453, #12945)
	- disable per-zone custom chains by default, they're rarely used

Additionally introduce options "device", "subnet", "extra", "extra_src" and "extra_dest"
to allow defining zones not related to uci interfaces, e.g. to match "ppp+" or any tcp
traffic to and from a specific port.
