Brad Fitzpatrick c4d0237e5c tstest/natlab: add dual stack with blackholed IPv4
This reproduces the bug report from
https://github.com/tailscale/tailscale/issues/13346

It does not yet fix it.

wgengine/netstack: implement netstack loopback (#13301)
When the TS_DEBUG_NETSTACK_LOOPBACK_PORT environment variable is set,
netstack will loop back (dnat to addressFamilyLoopback:loopbackPort)
TCP & UDP flows originally destined to localServicesIP:loopbackPort.
localServicesIP is quad-100 or the IPv6 equivalent.

Brad Fitzpatrick 0157000cab tstest/natlab: fix IPv6 tests, remove TODOs
The reason they weren't working was because the cmd/tta agent in the
guest was dialing out to the test and the vnet couldn't map its global
unicast IPv6 address to a node as it was just using a
map[netip.Addr]*node and blindly trusting the *node was
populated. Instead, it was nil, so the agent connection fetching
didn't work for its RoundTripper and the test could never drive the
node. That map worked for IPv4 but for IPv6 we need to use the method
that takes into account the node's IPv6 SLAAC address. Most call sites
had been converted but I'd missed that one.

Also clean up some debug, and prohibit nodes' link-local unicast
addresses from dialing 2000::/3 directly for now. We can allow that to
be configured opt-in later (some sort of IPv6 NAT mode. Whatever it's
called.) That mode was working on accident, but was confusing: Linux
would do source address selection from link local for the first few
seconds and then after SLAAC and DAD, switch to using the global
unicast source address. Be consistent for now and force it to use the
global unicast.

This adds a new NodeAgentClient type that can be used to
invoke the LocalAPI using the LocalClient instead of
handcrafted URLs. However, there are certain cases where
it does make sense for the node agent to provide more
functionality than whats possible with just the LocalClient,
as such it also exposes a http.Client to make requests directly.

Brad Fitzpatrick e968b0ecd7 cmd/tailscale,controlclient,ipnlocal: fix 'up', deflake tests more
The CLI's "up" is kinda chaotic and LocalBackend.Start is kinda
chaotic and they both need to be redone/deleted (respectively), but
this fixes some buggy behavior meanwhile. We were previously calling
StartLoginInteractive (to start the controlclient's RegisterRequest)
redundantly in some cases, causing test flakes depending on timing and
up's weird state machine.

We only need to call StartLoginInteractive in the client if Start itself
doesn't. But Start doesn't tell us that. So cheat a bit and a put the
information about whether there's a current NodeKey in the ipn.Status.
It used to be accessible over LocalAPI via GetPrefs as a private key but
we removed that for security. But a bool is fine.

So then only call StartLoginInteractive if that bool is false and don't
do it in the WatchIPNBus loop.

Maisem Ali af97e7a793 tailcfg,all: add/plumb Node.IsJailed
This adds a new bool that can be sent down from control
to do jailing on the client side. Previously this would
only be done from control by modifying the packet filter
we sent down to clients. This would result in a lot of
additional work/CPU on control, we could instead just
do this on the client. This has always been a TODO which
we keep putting off, might as well do it now.

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).

all: use zstdframe where sensible (#11491)
Use the zstdframe package where sensible instead of plumbing
around our own zstd.Encoder just for stateless operations.

This causes logtail to have a dependency on zstd,
but that's arguably okay since zstd support is implicit
to the protocol between a client and the logging service.
Also, virtually every caller to logger.NewLogger was
manually setting up a zstd.Encoder anyways,
meaning that zstd was functionally always a dependency.
