Since the tailscaled binaries that we distribute are static and don't
link cgo, we previously wouldn't fetch group IDs that are returned via
NSS. Try shelling out to the 'id' command, similar to how we call
'getent', to detect such cases.

There is an undocumented 16KiB limit for text log messages.
However, the limit for JSON messages is 256KiB.
Even worse, logging JSON as text results in significant overhead
since each double quote needs to be escaped.
Instead, use logger.Logf.JSON to explicitly log the info as JSON.
We also modify osdiag to return the information as structured data
rather than implicitly have the package log on our behalf.
This gives more control to the caller on how to log.

auto-updates are on.
Fix up those invalid prefs on profile reload, as a migration.

Creates new QNAP builder target, which builds go binaries then uses
docker to build into QNAP packages. Much of the docker/script code
here is pulled over from https://github.com/tailscale/tailscale-qpkg,
with adaptation into our builder structures.
The qnap/Tailscale folder contains static resources needed to build
Tailscale qpkg packages, and is an exact copy of the existing folder
in the tailscale-qpkg repo.
Builds can be run with:
```
sudo ./tool/go run ./cmd/dist build qnap
```

Since we already track active SSH connections, it's not hard to
proactively reject updates until those finish. We attempt to do the same
on the control side, but the detection latency for new connections is in
the minutes, which is not fast enough for common short sessions.
Handle a `force=true` query parameter to override this behavior, so that
control can still trigger an update on a server where some long-running
abandoned SSH session is open.

If this happens, it results in us pessimistically closing more
connections than might be necessary, but is more correct since we won't
"miss" a change to the default route interface and keep trying to send
data over a nonexistent interface, or one that can't reach the internet.

The Network Location Awareness service identifies networks authenticated against
an Active Directory domain and categorizes them as "Domain Authenticated".
This includes the Tailscale network if a Domain Controller is reachable through it.
If a network is categories as NLM_NETWORK_CATEGORY_DOMAIN_AUTHENTICATED,
it is not possible to override its category, and we shouldn't attempt to do so.
Additionally, our Windows Firewall rules should be compatible with both private
and domain networks.
This fixes both issues.

Containers are typically immutable and should be updated as a whole (and
not individual packages within). Deny enablement of auto-updates in
containers.
Also, add the missing check in EditPrefs in LocalAPI, to catch cases
like tailnet default auto-updates getting enabled for nodes that don't
support it.

Kubernetes cluster domain defaults to 'cluster.local', but can also be customized.
We need to determine cluster domain to set up in-cluster forwarding to our egress proxies.
This was previously hardcoded to 'cluster.local', so was the egress proxies were not usable in clusters with custom domains.
This PR ensures that we attempt to determine the cluster domain by parsing /etc/resolv.conf.
In case the cluster domain cannot be determined from /etc/resolv.conf, we fall back to 'cluster.local'.

Some editions of Windows server share the same build number as their
client counterpart; we must use an additional field found in the OS
version information to distinguish between them.
Even though "Distro" has Linux connotations, it is the most appropriate
hostinfo field. What is Windows Server if not an alternate distribution
of Windows? This PR populates Distro with "Server" when applicable.

Most of the magicsock tests fake the network, simulating packets going
out and coming in. There's no reason to actually hit your router to do
UPnP/NAT-PMP/PCP during in tests. But while debugging thousands of
iterations of tests to deflake some things, I saw it slamming my
router. This stops that.

This ensures that we close the underlying connection(s) when a major

between WiFi and cellular can result in leftover connections in the

This removes AWS and Kubernetes support from Linux binaries by default
on GOARCH values where people don't typically run on AWS or use
Kubernetes, such as 32-bit mips CPUs.
It primarily focuses on optimizing for the static binaries we
distribute. But for people building it themselves, they can set
ts_kube or ts_aws (the opposite of ts_omit_kube or ts_omit_aws) to
force it back on.
Makes tailscaled binary ~2.3MB (~7%) smaller.

When localAPI clients directly set ExitNodeID to "", the expected behaviour is that the prior exit node also gets zero'd - effectively setting the UI state back to 'no exit node was ever selected'
The IntenalExitNodePrior has been changed to be a non-opaque type, as it is read by the UI to render the users last selected exit node, and must be concrete. Future-us can either break this, or deprecate it and replace it with something more interesting.
