A new package can also later record/report which knobs are checked and
set. It also makes the code cleaner & easier to grep for env knobs.

* Revert "Revert "types/key: add MachinePrivate and MachinePublic.""

* types/key: add ControlPrivate, with custom serialization.
ControlPrivate is just a MachinePrivate that serializes differently
in JSON, to be compatible with how the Tailscale control plane
historically serialized its private key.

Plumb throughout the codebase as a replacement for the mixed use of
tailcfg.MachineKey and wgkey.Private/Public.

It was useful early in development when disco clients were the
exception and tailscale logs were noisier than today, but now
non-disco is the exception.

The netmaps can get really large.
Printing, processing, and uploading them is expensive.
Only print the header on an ongoing basis.

Add in UPnP portmapping, using goupnp library in order to get the UPnP client and run the
portmapping functions. This rips out anywhere where UPnP used to be in portmapping, and has a
flow separate from PMP and PCP.
RELNOTE=portmapper now supports UPnP mappings

Turns out we never reliably log the control plane URL a client connects
to. Do it here, and include the server public key, which might
inadvertently tell us something interesting some day.

So the NetworkMap-from-incremental-MapResponses can be tested easily.
And because direct.go was getting too big.
No change in behavior at this point. Just movement.

And fix PeerSeenChange bug where it was ignored unless there were
other peer changes.

Track endpoints internally with a new tailcfg.Endpoint type that
includes a typed netaddr.IPPort (instead of just a string) and
includes a type for how that endpoint was discovered (STUN, local,
etc).
Use []tailcfg.Endpoint instead of []string internally.
At the last second, send it to the control server as the existing
[]string for endpoints, but also include a new parallel
MapRequest.EndpointType []tailcfg.EndpointType, so the control server
can start filtering out less-important endpoint changes from
new-enough clients. Notably, STUN-discovered endpoints can be filtered
out from 1.6+ clients, as they can discover them amongst each other
via CallMeMaybe disco exchanges started over DERP. And STUN endpoints
change a lot, causing a lot of MapResposne updates. But portmapped
endpoints are worth keeping for now, as they they work right away
without requiring the firewall traversal extra RTT dance.
End result will be less control->client bandwidth. (despite negligible
increase in client->control bandwidth)

Instead of having the CLI check whether IP forwarding is enabled, ask
tailscaled. It has a better idea. If it's netstack, for instance, the
sysctl values don't matter. And it's possible that only the daemon has
permission to know.
