Remove restrictions on source and destination addresses, which aren't
specified on RFC8415, and for some reason in openwrt are configured
to allow both link-local and ULA addresses.
As cleared out in issue #5066 there are some ISPs that use Gloabal
Unicast addresses, so fix this rule to allow them.
Fixes: #5066

(cherry picked from commit 0d75aa27d4)
Running your firewall's "wan" zone in REJECT zone (1) exposes the
presence of the router, (2) depending on the sophistication of
fingerprinting tools might identify the OS and release running on
the firewall which then identifies known vulnerabilities with it
and (3) perhaps most importantly of all, your firewall can be
used in a DDoS reflection attack with spoofed traffic generating
ICMP Unreachables or TCP RST's to overwhelm a victim or saturate
his link.
This rule, when enabled, allows traceroute to work even when the
default input policy of the firewall for the wan zone has been
set to DROP.

509e673 firewall3: Improve ipset support
The enabled option did not work properly for ipsets, as it was not
checked on create/destroy of a set. After this commit, sets are only
created/destroyed if enabled is set to true.
Add support for reloading, or recreating, ipsets on firewall reload. By
setting "reload_set" to true, the set will be destroyed and then
re-created when the firewall is reloaded.
Add support for the counters and comment extensions. By setting
"counters" or "comment" to true, then counters or comments are added to
the set.

Firewall rules don't work as intended without conntrack support. The recent
cleanup removed the kmod-nf-conntrack6 dependency from the iptables
modules; add it to the firewall package instead.

Packets which are merely forwarded by the router and which are neither
involved in any DNAT/SNAT nor originate locally, are considered INVALID
from a conntrack point of view, causing them to get dropped in the
zone_*_dest_ACCEPT chains, since those only allow stream with state NEW
or UNTRACKED.
Remove the ctstate restriction on dest accept chains to properly pass-
through unrelated 3rd party traffic.
