`cmd/derpprobe --once` didn’t respect the convention of non-zero exit
status for a failed run. It would always exit zero (i.e. success),
even. This patch fixes that, but only for `--once` mode.

In this PR, we make DNS registration behavior configurable via the EnableDNSRegistration policy setting.
We keep the default behavior unchanged, but allow admins to either enforce DNS registration and dynamic
DNS updates for the Tailscale interface, or prevent Tailscale from modifying the settings configured in
the network adapter's properties or by other means.

Add new rules to update DNAT rules for Kubernetes operator's
HA ingress where it's expected that rules will be added/removed
frequently (so we don't want to keep old rules around or rewrite
existing rules unnecessarily):
- allow deleting DNAT rules using metadata lookup
- allow inserting DNAT rules if they don't already
exist (using metadata lookup)

In tailssh.go:1284, (*sshSession).startNewRecording starts a fire-and-forget goroutine that can
outlive the test that triggered its creation. Among other things, it uses ss.logf, and may call it
after the test has already returned. Since we typically use (*testing.T).Logf as the logger,
this results in a data race and causes flaky tests.
Ideally, we should fix the root cause and/or use a goroutines.Tracker to wait for the goroutine
to complete. But with the release approaching, it's too risky to make such changes now.
As a workaround, we update the tests to use tstest.WhileTestRunningLogger, which logs to t.Logf
while the test is running and disables logging once the test finishes, avoiding the race.
While there, we also fix TestSSHAuthFlow not to use log.Printf.

The event loop removes the need for growing locking complexities and
synchronization. Now we simply use channels. The event loop only runs
while there is active work to do.
relayManager remains no-op inside magicsock for the time being.
endpoints are never 'relayCapable' and therefore endpoint & Conn will
not feed CallMeMaybeVia or allocation events into it.
A number of relayManager events remain unimplemented, e.g.
CallMeMaybeVia reception and relay handshaking.

Commit 4b525fdda (ssh/tailssh: only chdir incubator process to user's
homedir when necessary and possible, 2024-08-16) defers changing the
working directory until the incubator process drops its privileges.
However, it didn't account for the case where there is no incubator
process, because no tailscaled was found on the PATH. In that case, it
only intended to run `tailscaled be-child` in the root directory but
accidentally ran everything there.

This is an integration test that covers all the code in Direct, Auto, and

tsnet as a convenient proxy for setting up all the client pieces correctly,
but is not actually a test specific to tsnet.

Until we turn on AAAA by default (which might make some people rely on
Happy Eyeballs for targets without IPv6), this lets people turn it on
explicitly if they want.
We still should add a peer cap as well in the future to let a peer
explicitly say that it's cool with IPv6.

relayManager will eventually be responsible for handling the allocation
and handshaking of UDP relay server endpoints.
relay servers are endpoint-independent, and Conn must already maintain
handshake state for all endpoints. This justifies a new data structure
to fill these roles.

Previously all tests shared their tailscale+tailscaled binaries in
system /tmp directories, which often leaked, and required TestMain to
clean up (which feature/taildrop didn't use).
This makes it use testing.T.TempDir for the binaries, but still only
builds them once and efficiently as possible depending on the OS
copies them around between each test's temp dir.
