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.

35497a0400 firewall: link iptables extensions dynamically
Use shared libipt{,4,6}ext.so libraries instead of statically linking
the userspace matches into the fw3 executable.

As a side effect the match initialization is extremely simplified
compared to the weak function pointer juggling performed before.

This also fixes the initialization of the multiport match.

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.

c10d97484a Add more license tags with SPDX identifiers
Note, that licensing stuff is a nightmare: many packages does not clearly
state their licenses, and often multiple source files are simply copied
together - each with different licensing information in the file headers.

I tried hard to ensure, that the license information extracted into the OpenWRT's
makefiles fit the "spirit" of the packages, e.g. such small packages which
come without a dedicated source archive "inherites" the OpenWRT's own license
in my opinion.

However, I can not garantee that I always picked the correct information
and/or did not miss license information.

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."
