Noticed these in MapResponses to clients.
MachineAuthorized was set true, but once we fix the coordination server
to zero out that field, then it can be omittted.
The cloner tool adds static checks that the Clone methods are up to
date, so failing to update Clone causes a compiler error.

These accidentally make the tag syntax more flexible than was intended,
which will create forward compatibility problems later. Let's go back
to the old stricter parser.
Revert "cmd/tailscale/cli: fix double tag: prefix in tailscale up"
Revert "cmd/tailscale/cli, tailcfg: allow tag without "tag:" prefix in 'tailscale up'"

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.

Also replaces the IPv6Overlay bool with use of DebugFlags, since
it's currently an experimental configuration.

I was going to make support for this advertised from the client, but
turns out only "tailscale status" even uses the UserProfiles field and
fails gracefully (omits that field) if a user profile for a user is
missing, so I think we can just reuse the DeltaPeers field from the
client to ask the control server to also delta encode the user
profiles.
For the few users running 1.1.x (unstable) versions between DeltaPeers
support (1.1.82) and this (~1.1.541), they'll just sometimes have
missing names in "tailscale status --json" or "tailscale status --web"
(the only places the UserProfile is used).
DebugForceDisco was a development & safety knob during the the transition
to discovery. It's no longer needed.
Add MapRequest.ReadOnly to prevent clients needing to do two
peer-spamming MapRequest at start-up.
This only adds the field, not the use of the field. (The control server
needs to support it first.)

We're beginning to reference DERP region names in the admin UI, so it's
best to consolidate this information in our DERP map.

If there's been 5 minutes of inactivity, stop doing STUN lookups. That
means NAT mappings will expire, but they can resume later when there's
activity again.
We'll do this for all platforms later.

Instead of hard-coding the DERP map (except for cmd/tailscale netcheck
for now), get it from the control server at runtime.
And make the DERP map support multiple nodes per region with clients
picking the first one that's available. (The server will balance the
order presented to clients for load balancing)
This deletes the stunner package, merging it into the netcheck package
instead, to minimize all the config hooks that would've been
required.
Also fix some test flakes & races.

Also stop logging data sent/received from nodes we're not connected to (ie all those `x`s being logged in the `peers: ` line)

These will be used for dynamically changing the identity of a node, so
its ACL rights can be different from your own.
Note: Not all implemented yet on the server side, but we need this so
we can request the tagged rights in the first place.

This depends on improved support from the control server, to send the
new subnet width (Bits) fields. If these are missing, we fall back to
assuming their value is /32.
Conversely, if the server sends Bits fields to an older client, it will
interpret them as /32 addresses. Since the only rules we allow are
"accept" rules, this will be narrower or equal to the intended rule, so
older clients will simply reject hosts on the wider subnet (fail
closed).
With this change, the internal filter.Matches format has diverged
from the wire format used by controlclient, so move the wire format
into tailcfg and convert it to filter.Matches in controlclient.

We still include them directly in the controlclient network map

* adds new packet "netcheck" to do the checking of UDP, IPv6, and
nearest DERP server, and the Report type for all that (and more
in the future, probably pulling in danderson's natprobe)
* new tailcfg.NetInfo type
* cmd/tailscale netcheck subcommand (tentative name, likely to
change/move) to print out the netcheck.Report.
