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.

0e3048d8e0 control/controlclient: support delta userprofiles from control 
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).

904a91038a tailcfg: add MapRequest.ReadOnly and OmitPeers; remove DebugForceDisco 
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.)

e6b84f2159 all: make client use server-provided DERP map, add DERP region support 
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.

Fixes #387 (Don't hard-code the DERP map)
Updates #388 (Add DERP region support)
Fixes #399 (wgengine: flaky tests)
