Maisem Ali e67069550b ipn/ipnlocal,net/tstun,wgengine: create and plumb jailed packet filter
This plumbs a packet filter for jailed nodes through to the
tstun.Wrapper; the filter for a jailed node is equivalent to a "shields
up" filter. Currently a no-op as there is no way for control to
tell the client whether a peer is jailed.

Nick Khyl caa3d7594f ipn/ipnlocal, net/tsdial: plumb routes into tsdial and use them in UserDial
We'd like to use tsdial.Dialer.UserDial instead of SystemDial for DNS over TCP.
This is primarily necessary to properly dial internal DNS servers accessible
over Tailscale and subnet routes. However, to avoid issues when switching
between Wi-Fi and cellular, we need to ensure that we don't retain connections
to any external addresses on the old interface. Therefore, we need to determine
which dialer to use internally based on the configured routes.

This plumbs routes and localRoutes from router.Config to tsdial.Dialer,
and updates UserDial to use either the peer dialer or the system dialer,
depending on the network address and the configured routes.

It's deprecated and using it gets us the old slow behavior
according to https://go.dev/blog/randv2.

> back to the mutex-protected Go 1 generator.

Brad Fitzpatrick 96712e10a7 health, ipn/ipnlocal: move more health warning code into health.Tracker
In prep for making health warnings rich objects with metadata rather
than a bunch of strings, start moving it all into the same place.

We'll still ultimately need the stringified form for the CLI and
LocalAPI for compatibility but we'll next convert all these warnings
into Warnables that have severity levels and such, and legacy
stringification will just be something each Warnable thing can do.

Shaw Drastin 1fe073098c
Reset dial plan when switching profile (#11933)
When switching profile, the server URL can change (e.g.
because of switching to a self-hosted headscale instance).

If it is not reset here, dial plans returned by old
server (e.g. tailscale control server) will be used to
connect to new server (e.g. self-hosted headscale server),
and the register request will be blocked by it until
timeout, leading to very slow profile switches.

Brad Fitzpatrick 3672f29a4e net/netns, net/dns/resolver, etc: make netmon required in most places
The goal is to move more network state accessors to netmon.Monitor
where they can be cheaper/cached. But first (this change and others)
we need to make sure the one netmon.Monitor is plumbed everywhere.

Some notable bits:

* tsdial.NewDialer is added, taking a now-required netmon

* because a tsdial.Dialer always has a netmon, anything taking both
  a Dialer and a NetMon is now redundant; take only the Dialer and
  get the NetMon from that if/when needed.

* netmon.NewStatic is added, primarily for tests

Brad Fitzpatrick 723c775dbb tsd, ipnlocal, etc: add tsd.System.HealthTracker, start some plumbing
This adds a health.Tracker to tsd.System, accessible via
a new tsd.System.HealthTracker method.

In the future, that new method will return a tsd.System-specific
HealthTracker, so multiple tsnet.Servers in the same process are
isolated. For now, though, it just always returns the temporary
health.Global value. That permits incremental plumbing over a number
of changes. When the second to last health.Global reference is gone,
then the tsd.System.HealthTracker implementation can return a private
Tracker.

The primary plumbing this does is adding it to LocalBackend and its
dozen and change health calls. A few misc other callers are also
plumbed. Subsequent changes will flesh out other parts of the tree
(magicsock, controlclient, etc).

ipn/ipnlocal,ssh/tailssh: reject c2n /update if SSH conns are active (#11820)
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.

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.
