Removed direct ip -6 use from pm_v6_route (it was spurious - if_table provides the interface we should use).
Removed unused linux_if require.
Made separate function or two out of dns config.
Added PIL-style multiple inheritance and fixed strict module usage.
Fixed two undefined references (thanks, strict) in debug messages.
Added multiple inherited init/unint too, yay.
Converted mdns_core to use multiple inheritance + avoiding mcastjoiner uninit as it would call detach_skv, without attach done.
Instead of v, use descriptive lap.
Added support for deriving upstream server from OSPF (prefer v6, then v4, and finally Google as fallback).
Preliminary integration with hybrid proxy.
