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 c25ecddd1b tailcfg: remove UserProfile.Roles field, add tests for legacy behavior
Old macOS clients required we populate this field to a non-null

Instead, keep the field but change its type to a custom empty struct
that can marshal/unmarshal JSON. And lock it in with a test.

control/controlclient: sign RegisterRequest (#1549)
control/controlclient: sign RegisterRequest

Some customers wish to verify eligibility for devices to join their
tailnets using machine identity certificates. TLS client certs could
potentially fulfill this role but the initial customer for this feature
has technical requirements that prevent their use. Instead, the
certificate is loaded from the Windows local machine certificate store
and uses its RSA public key to sign the RegisterRequest message.

There is room to improve the flexibility of this feature in future and
it is currently only tested on Windows (although Darwin theoretically
works too), but this offers a reasonable starting place for now.

Brad Fitzpatrick 4145bb7148 tailcfg: bump CurrentMapRequestVersion, forgotten earlier
In f45a9e291b (2021-03-04), I tried to bump CurrentMapRequestVersion
to 12 but only documented the meaning of 12 but forgot to actually
increase it from 11.

Mapver 11 was added in ea49b1e811 (2021-03-03).

Fix this in its own commit so we can cherry-pick it to the 1.6 release
branch.

Brad Fitzpatrick f45a9e291b tailcfg, control/controlclient: add MapResponse.PingRequest
So the control server can test whether a client's actually present.

Most clients are over HTTP/2, so these pings (to the same host) are
super cheap.

This mimics the earlier goroutine dump mechanism.

ipn: delete domainsForProxying, require explicit DNS search domains (mapver 9) (#1078)
Previously the client had heuristics to calculate which DNS search domains
to set, based on the peers' names. Unfortunately that prevented us from
doing some things we wanted to do server-side related to node sharing.

So, bump MapRequest.Version to 9 to signal that the client only uses the
explicitly configured DNS search domains and doesn't augment it with its own
list.

the remaining bandwidth for streamed MapResponses were redundant,
unchanged PacketFilters. So make MapRequest.Version 6 mean that nil
means unchanged from the previous value.
