All the magic service names with virtual IPs will need IPv6 variants.
Pull this out in prep.

The natlab Test Agent (tta) still had its old log streaming hack in
place where it dialed out to anything on TCP port 124 and those logs
were streamed to the host running the tests. But we'd since added gokrazy
syslog streaming support, which made that redundant.
So remove all the port 124 stuff. And then make sure we log to stderr
so gokrazy logs it to syslog.
Also, keep the first 1MB of logs in memory in tta too, exported via
localhost:8034/logs for interactive debugging. That was very useful
during debugging when I added IPv6 support. (which is coming in future
PRs)

updates tailcale/corp#22371
For dgram mode, we need to store the write addresses of
the client socket(s) alongside the writer functions and
the write operation needs to use WriteToUnix.
Unix also has multiple clients writing to the same socket,
so the serve method is modified to handle packets from
multiple mac addresses.
Cleans up a bit of cruft from the initial tailmac tooling
commit.
Now all the macOS packets are belong to us.

We had a mix of 0-based and 1-based nodes and MACs in logs.

This is much lower latency than logcatcher, which is higher latency
and chunkier. And this is better than getting it via 'tailscale debug
daemon-logs', which misses early interesting logs.

In particular, tests showing that #3824 works. But that test doesn't
actually work yet; it only gets a DERP connection. (why?)

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.

And don't make guests under vnet/natlab upload to logcatcher,
as there won't be a valid cert anyway.
