Registering a new store is cheap, it just adds a map entry. No need to
lazy-init it with sync.Once and an intermediate slice holding init
functions.

This type improves code clarity and reduces the chance of heap alloc as
we pass it as a non-pointer. VNI being a 3-byte value enables us to
track set vs unset via the reserved/unused byte.

Taildrop wasn't working on iOS since #15971 because GetExt didn't work
until after init, but that PR moved Init until after Start.
This makes GetExt work before LocalBackend.Start (ExtensionHost.Init).

The same message was used for "up" and "down" permission failures, but
"set" works better for both. Suggesting "up --operator" for a "down"
permission failure was confusing.
It's not like the latter command works in one shot anyway.

This fixes the implementation and test from #15208 which apparently
never worked.
Ignore the metacert when counting the number of expected certs
presented.
And fix the test, pulling out the TLSConfig setup code into something
shared between the real cmd/derper and the test.

This reconciler allows users to make applications highly available at L3 by
leveraging Tailscale Virtual Services. Many Kubernetes Service's
(irrespective of the cluster they reside in) can be mapped to a
Tailscale Virtual Service, allowing access to these Services at L3.

cmd/containerboot,kube/ingressservices: proxy VIPService TCP/UDP traffic to cluster Services
This PR is part of the work to implement HA for Kubernetes Operator's
network layer proxy.
Adds logic to containerboot to monitor mounted ingress firewall configuration rules
and update iptables/nftables rules as the config changes.
Also adds new shared types for the ingress configuration.
The implementation is intentionally similar to that for HA for egress proxy.

Currently, LocalBackend/ExtensionHost doesn't invoke the profile change callback for the initial profile.
Since the initial profile may vary depending on loaded extensions and applied policy settings,
it can't be reliably determined until all extensions are initialized. Additionally, some extensions
may asynchronously trigger a switch to the "best" profile (based on system state and policy settings) during
initialization.
We intended to address these issues as part of the ongoing profileManager/LocalBackend refactoring,
but the changes didn't land in time for the v1.84 release and the Taildrop refactoring.
In this PR, we update the Taildrop extension to retrieve the current profile at initialization time
and handle it as a profile change.
We also defer extension initialization until LocalBackend has started, since the Taildrop extension
already relies on this behavior (e.g., it requires clients to call SetDirectFileRoot before Init).

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.
