tstest/integration/vms: use hujson.Standardize instead of hujson.Unmarshal (#4520)
The hujson package transition to just being a pure AST
parser and formatter for HuJSON and not an unmarshaler.

Thus, parse HuJSON as such, convert it to JSON,
and then use the standard JSON unmarshaler.

words: after a Series of discussions, Bees should be included (#4606)
There has been a lot of talk about Bees at Tailscale recently, and
naturally, with it being Tailscale, we thought to ourselves:

Do Bees have a tail and/or scales?

Tailscale has a long track record of scientific rigor around the
validity of the inclusions on the tails and scales list, and this time
will be no exception.

Our research has found that Bees, in particular the Honey Bee, produces
wax scales on their abdomens and thus should be included. As for tails;

'Stabby-tails' - Tailscale Employee, 2022

No further justification needed, it will be included.

This change includes Bee in both tails.txt and scales.txt.

Maisem Ali c60cbca371 control/controlclient: store netinfo and hostinfo separately
Currently, when SetNetInfo is called it sets the value on
hostinfo.NetInfo. However, when SetHostInfo is called it overwrites the
hostinfo field which may mean it also clears out the NetInfo it had just
received.
This commit stores NetInfo separately and combines it into Hostinfo as
needed so that control is always notified of the latest values.

Also, remove unused copies of Hostinfo from ipn.Status and
controlclient.Auto.

Tom DNetto 9e77660931 net/tstun,wgengine/{.,netstack}: handle UDP magicDNS traffic in netstack
This change wires netstack with a hook for traffic coming from the host
into the tun, allowing interception and handling of traffic to quad-100.

With this hook wired, magicDNS queries over UDP are now handled within
netstack. The existing logic in wgengine to handle magicDNS remains for now,
but its hook operates after the netstack hook so the netstack implementation
takes precedence. This is done in case we need to support platforms with
netstack longer than expected.

Tom DNetto 5b85f848dd net/dns,net/dns/resolver: refactor channels/magicDNS out of Resolver
Moves magicDNS-specific handling out of Resolver & into dns.Manager. This
greatly simplifies the Resolver to solely issuing queries and returning
responses, without channels.

Enforcement of max number of in-flight magicDNS queries, assembly of
synthetic UDP datagrams, and integration with wgengine for
recieving/responding to magicDNS traffic is now entirely in Manager.
This path is being kept around, but ultimately aims to be deleted and
replaced with a netstack-based path.

This commit is part of a series to implement magicDNS using netstack.

Aaron Klotz d915e0054c cmd/tailscaled: change Windows service shutdown and add optional event logging
Once a stop request is received and the service updates its status to `svc.StopPending`,
it should continue running *until the shutdown sequence is complete*, and then
return out of `(*ipnService).Execute`, which automatically sends a `svc.Stopped`
notification to Windows.

To make this happen, I changed the loop so that it runs until `doneCh` is
closed, and then returns. I also removed a spurious `svc.StopPending` notification
that the Windows Service Control Manager might be interpreting as a request for
more time to shut down.

Finally, I added some optional logging that sends a record of service notifications
to the Windows event log, allowing us to more easily correlate with any Service
Control Manager errors that are sent to the same log.

ipn: remove enforceDefaults option from PrefsFromBytes
The Mac client was using it, but it had the effect of the `RouteAll`
("Use Tailscale subnets") pref always being enabled at startup,
regardless of the persisted value.

enforceDefaults was added to handle cases from ~2 years ago where
we ended up with persisted `"RouteAll": false` values in the keychain,
but that should no longer be a concern. New users will get the default
of it being enabled via `NewPrefs`.

There will be a corresponding Mac client change to stop passing in
enforceDefaults.
