Brad Fitzpatrick 34d2f5a3d9 tailcfg: add Endpoint, EndpointType, MapRequest.EndpointType
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)

Brad Fitzpatrick db5e269463 client/tailscale/apitype: move local API types to new apitype package
They were scattered/duplicated in misc places before.

It can't be in the client package itself for circular dep reasons.

This new package is basically tailcfg but for localhost
communications, instead of to control.

Brad Fitzpatrick 9972c02b60 cmd/tailscale/cli: don't let up change prefs based on implicit flag values
This changes the behavior of "tailscale up".

Previously "tailscale up" always did a new Start and reset all the settings.

Now "tailscale up" with no flags just brings the world [back] up.
(The opposite of "tailscale down").

But with flags, "tailscale up" now only is allowed to change
preferences if they're explicitly named in the flags. Otherwise it's
an error. Or you need to use --reset to explicitly nuke everything.

Brad Fitzpatrick 4c3f7c06fc ipn/ipnlocal: be consistent in not logging when no notify registered
Some paths already didn't. And in the future I hope to shut all the
notify funcs down end-to-end when nothing is connected (as in the
common case in tailscaled).  Then we can save some JSON encoding work.

Brad Fitzpatrick d9ee9a0d3f ipn: set BackendServer's notify earlier; don't require Start
We've been slowly making Start less special and making IPN a

David Anderson da4cc8bbb4 net/dns: handle all possible translations of high-level DNS config.
With this change, all OSes can sort-of do split DNS, except that the
default upstream is hardcoded to 8.8.8.8 pending further plumbing.
Additionally, Windows 8-10 can do split DNS fully correctly, without
the 8.8.8.8 hack.

Part of #953.

David Anderson 90f82b6946 net/dns/resolver: add live reconfig, plumb through to ipnlocal.
The resolver still only supports a single upstream config, and
ipn/wgengine still have to split up the DNS config, but this moves
closer to unifying the DNS configs.

As a handy side-effect of the refactor, IPv6 MagicDNS records exist
now.
