For now just checks that we can build cmd/tailscale/cli, will be
broadened once we can actually build more things.

Adds a stub for syscall.Exec when GOOS=js. We also had a separate branch
for Windows, might as well use the same mechanism there too.

Allows instances that are running with the same machine ID (due to
cloning) to be distinguished.
Also adds sequence numbers to detect duplicates.

Fixes https://github.com/tailscale/corp/issues/5198
The upstream forwarder will block indefinitely on `udpconn.ReadFrom` if no
reply is recieved, due to the lack of deadline on the connection object.
There still isn't a deadline on the connection object, but the automatic closing
of the context on deadline expiry will close the connection via `closeOnCtxDone`,
unblocking the read and resulting in a normal teardown.

This fixes the "tailscale up --authkey=... --ssh" path (or any "up"
path that used Start instead of EditPrefs) which wasn't setting the
bit.

Profiling identified this as a fairly hot path for growing a slice.
Given this is only used in control & when a new packet filter is received, this shouldnt be hot in the client.
The prefix is a signal to tsweb to treat this as a gauge metric when
generating the Prometheus version.

We were marking them as gauges, but they are only ever incremented,
thus counter is more appropriate.

statedir is passed, then state is statedir/tailscaled.state.

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.

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.

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.

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.
