This test is not regularly passing on CI, but seems to pass reliably
locally. Needs deeper debugging.

tsnet.Server.Close was calling listener.Close with the server mutex
held, but the listener close method tries to grab that mutex, resulting
in a deadlock.

Previously, it would accept all TCP connections and then close the ones
it did not care about. Make it only ever accept the connections that it
cares about.

Add a DNS server which always responds as its own IP addresses.
Additionally add a tsnet TailscaleIPs() function to return the
IP addresses, both IPv4 and IPv6.

Some languages do not give you any useful access to the sockets
underlying their networking packages. E.g. java.net.http.HttpClient
provides no official access to its dialing logic.
...but everyone supports proxies. So add a SOCKS5 proxy on the listener
we are already running.
(The function being revamped is very new,
I only added it in the last week and it wasn't part of any release,
so I believe it is fine to redo its function signature.)

No ListenPacket support yet, but Listen with a udp network type fit
easier into netstack's model to start.
Then added an example of using it to cmd/sniproxy with a little udp
:53 handler.
No tests in tsnet yet because we don't have support for dialing over
UDP in tsnet yet. When that's done, a new test can test both sides.

This is for use by LocalAPI clients written in other languages that
don't appear to be able to talk HTTP over a socket (e.g.
java.net.http.HttpClient).

This updates all source files to use a new standard header for copyright
and license declaration. Notably, copyright no longer includes a date,
and we now use the standard SPDX-License-Identifier header.
This commit was done almost entirely mechanically with perl, and then
some minimal manual fixes.

Allow callers to verify that a net.Listener is a tsnet.listener by type
asserting against this Server method, as well as providing access to the
underlying Server.
This is initially being added to support the caddy integration in
caddyserver/caddy#5002.
