Import miniupnpd from routing repo and bump to 20180422.
Drop 102-ipv6-ext-port.patch as this looks upstreamed in the pinhole
code to me.
Consolidate all other patches & update with a view to sending upstream.
Add support for runtime IGDv1 mode switch (default to IGDv2)
(not extensively) Tested-on: ar71xx Archer C7 v2 in IGDv1 compatibility
mode. A variety of devices/applications appear to be able to create
mappings.
Have an attempt at resolving https://github.com/openwrt-routing/packages/issues/286
TL;DR miniupnpd rules get processed before fw3 rules and thus can
override existing/intended redirects. Ideally the miniupnpd rules would
be last in the relevant chains, unfortunately fw3 can sometimes use the
last rule as a REJECT. Put miniupnpd rules as penultimate.
