net/portmapper: add NAT-PMP client, move port mapping service probing * move probing out of netcheck into new net/portmapper package * use PCP ANNOUNCE op codes for PCP discovery, rather than causing short-lived (sub-second) side effects with a 1-second-expiring map + delete. * track when we heard things from the router so we can be less wasteful in querying the router's port mapping services in the future * use portmapper from magicsock to map a public port Fixes #1298 Fixes #1080 Fixes #1001 Updates #864 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com> 2021-02-20 06:15:41 +00:00			`// Copyright (c) 2021 Tailscale Inc & AUTHORS All rights reserved.`
