Brad Fitzpatrick dda03a911e wgengine/monitor: change API to permit multiple independent callbakcks
Currently it assumes exactly 1 registered callback. This changes it to
support 0, 1, or more than 1.

This is a step towards plumbing wgengine/monitor into more places (and
moving some of wgengine's interface state fetching into monitor in a
later step)

Brad Fitzpatrick c64bd587ae 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

"go mod tidy" would then cleanup. Also added a non-ignore build tag to

Brad Fitzpatrick 2d96215d97 wgengine/router: make Linux delRoute idempotent, cidrDiff fail late as possible
This makes cidrDiff do as much as possible before failing, and makes a
delete of an already-deleted rule be a no-op. We should never do this
ourselves, but other things on the system can, and this should help us
recover a bit.

Also adds the start of root-requiring tests.

TODO: hook into wgengine/monitor and notice when routes are changed
behind our back, and invalidate our routes map and re-read from
kernel (via the ip command) at least on the next reconfig call.
