David Anderson 8f5b52e571 net/netns: add windows support.
Also remove rebinding logic from the windows router. Magicsock will
instead rebind based on link change signals.

Josh Bleecher Snyder 7bd89359c9 cmd/cloner: generate a package-level Clone function
This Clone function knows how to clone any types
for which it has generated Clone methods.
This allows callers to efficiently clone
an inbound interface{} that might contain one of these types.

Josh Bleecher Snyder 2352690bde cmd/cloner: ensure cloner gets re-run when structs change
If you change a struct and don't re-run cloner,
your Cloner method might be inaccurate, leading to bad things.

To prevent this, write out the struct as it is at the moment that
cloner is caller, and attempt a conversion from that type.
If the struct gets changed in any way, this conversion will fail.

This will yield false positives: If you change a non-pointer field,
you will be forced to re-run cloner, even though the actual generated
code won't change. I think this is an acceptable cost: It is a minor
annoyance, which will prevent real bugs.

Brad Fitzpatrick e415991256 derp, derp/derphttp: remove one RTT from DERP setup
* advertise server's DERP public key following its ServerHello
* have client look for that DEPR public key in the response
  PeerCertificates
* let client advertise it's going into a "fast start" mode
  if it finds it
* modify server to support that fast start mode, just not
  sending the HTTP response header

Cuts down another round trip, bringing the latency of being able to
write our first DERP frame from SF to Bangalore from ~725ms
(3 RTT) to ~481ms (2 RTT: TCP and TLS).

Fixes #693

in profiles or panics to corresponding source code.

It'll also let us observe version changes in prometheus.

Brad Fitzpatrick 4aba86cc03 ipn/ipnserver: make Engine argument a func that tries again for each connection
So a backend in server-an-error state (as used by Windows) can try to
create a new Engine again each time somebody re-connects, relaunching
the GUI app.

(The proper fix is actually fixing Windows issues, but this makes things better
in the short term)
