David Anderson cf361bb9b1 net/dns: remove PerDomain from Config.
It's currently unused, and no longer makes sense with the upcoming
DNS infrastructure. Keep it in tailcfg for now, since we need protocol
compat for a bit longer.

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
value so we were unable to remove this field before.

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.

The code is not obviously better or worse, but this makes the little warning
triangle in my editor go away, and the distraction removal is worth it.

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 0a84359d2d tailcfg, net/netcheck: let control mark "Avoid" bit on DERP regions
So a region can be used if needed, but won't be STUN-probed or used as
its home.

This gives us another possible debugging mechanism for #1310, or can
be used as a short-term measure against DERP flip-flops for people
equidistant between regions if our hysteresis still isn't good enough.

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.

Josh Bleecher Snyder 56a7652dc9 wgkey: new package
This is a replacement for the key-related parts
of the wireguard-go wgcfg package.

This is almost a straight copy/paste from the wgcfg package.
I have slightly changed some of the exported functions and types
to avoid stutter, added and tweaked some comments,
and removed some now-unused code.

To avoid having wireguard-go depend on this new package,
wgcfg will keep its key types.

We translate into and out of those types at the last minute.
These few remaining uses will be eliminated alongside
the rest of the wgcfg package.

Brad Fitzpatrick d21956436a ipn, tailcfg: change Windows subnet disabling behavior w/ WPAD
In 1.0, subnet relays were not specially handled when WPAD+PAC was
present on the network.

In 1.2, on Windows, subnet relays were disabled if WPAD+PAC was
present. That was what some users wanted, but not others.

This makes it configurable per domain, reverting back to the 1.0
default state of them not being special. Users who want that behavior
can then enable it.
