We had an ordered set type (set.Slice) already but we occasionally want
to do the same thing with a map, preserving the order things were added,
so add that too, as mapsx.OrderedMap[K, V], and then use in ipnext.

QNAP now requires builds to be signed with an HSM.
This removes support for signing with a local keypair.
This adds support for signing with a Google Cloud hosted key.
The key should be an RSA key with protection level `HSM` and that uses PSS padding and a SHA256 digest.
The GCloud project, keyring and key name are passed in as command-line arguments.
The GCloud credentials and the PEM signing certificate are passed in as Base64-encoded command-line arguments.

In preparation for adding more parameters (and later, moving some away), rework
the portmapper constructor to accept its arguments on a Config struct rather
than positionally.
This is a breaking change to the function signature, but one that is very easy
to update, and a search of GitHub reveals only six instances of usage outside
clones and forks of Tailscale itself, that are not direct copies of the code
fixed up here.
While we could stub in another constructor, I think it is safe to let those
folks do the update in-place, since their usage is already affected by other
changes we can't test for anyway.

This feature is "registered" as an ipnlocal.Extension, and
conditionally linked depending on GOOS and ts_omit_relayserver build
tag.
The feature is not linked on iOS in attempt to limit the impact to
binary size and resulting effect of pushing up against NetworkExtension
limits. Eventually we will want to support the relay server on iOS,
specifically on the Apple TV. Apple TVs are well-fitted to act as
underlay relay servers as they are effectively always-on servers.
This skeleton begins to tie a PeerAPI endpoint to a net/udprelay.Server.
The PeerAPI endpoint is currently no-op as
extension.shouldRunRelayServer() always returns false. Follow-up commits
will implement extension.shouldRunRelayServer().

In this PR, we refactor the LocalBackend extension system, moving from direct callbacks to a more organized extension host model.
Specifically, we:
- Extract interface and callback types used by packages extending LocalBackend functionality into a new ipn/ipnext package.
- Define ipnext.Host as a new interface that bridges extensions with LocalBackend.
It enables extensions to register callbacks and interact with LocalBackend in a concurrency-safe, well-defined, and controlled way.
- Move existing callback registration and invocation code from ipnlocal.LocalBackend into a new type called ipnlocal.ExtensionHost,
implementing ipnext.Host.
- Improve docs for existing types and methods while adding docs for the new interfaces.
- Add test coverage for both the extracted and the new code.
- Remove ipn/desktop.SessionManager from tsd.System since ipn/desktop is now self-contained.
- Update existing extensions (e.g., ipn/auditlog and ipn/desktop) to use the new interfaces where appropriate.
We're not introducing new callback and hook types (e.g., for ipn.Prefs changes) just yet, nor are we enhancing current callbacks,
such as by improving conflict resolution when more than one extension tries to influence profile selection via a background profile resolver.
These further improvements will be submitted separately.

This flag is currently no-op and hidden. The flag does round trip
through the related pref. Subsequent commits will tie them to
net/udprelay.Server. There is no corresponding "tailscale up" flag,
enabling/disabling of the relay server will only be supported via
"tailscale set".
This is a string flag in order to support disablement via empty string
as a port value of 0 means "enable the server and listen on a random
unused port". Disablement via empty string also follows existing flag
convention, e.g. advertise-routes.
Early internal discussions settled on "tailscale set --relay="<port>",
but the author felt this was too ambiguous around client vs server, and
may cause confusion in the future if we add related flags.

`tailscale set` was created to set preferences, which used to be
overloaded into `tailscale up`. To move people over to the new
command, `up` was supposed to be frozen and no new preference flags
would be added. But people forgot, there was no test to warn them, and
so new flags were added anyway.
TestUpFlagSetIsFrozen complains when new flags are added to
`tailscale up`. It doesn’t try all combinations of GOOS, but since
the CI builds in every OS, the pull-request tests should cover this.

Ensure no services are advertised as part of shutting down tailscaled.
Prefs are only edited if services are currently advertised, and they're
edited we wait for control's ~15s (+ buffer) delay to failover.
Note that editing prefs will trigger a synchronous write to the state
Secret, so it may fail to persist state if the ProxyGroup is getting
scaled down and therefore has its RBAC deleted at the same time, but that
failure doesn't stop prefs being updated within the local backend,
doesn't affect connectivity to control, and the state Secret is
about to get deleted anyway, so the only negative side effect is a harmless
error log during shutdown. Control still learns that the node is no
longer advertising the service and triggers the failover.
Note that the first version of this used a PreStop lifecycle hook, but
that only supports GET methods and we need the shutdown to trigger side
effects (updating prefs) so it didn't seem appropriate to expose that
functionality on a GET endpoint that's accessible on the k8s network.

control strategies, proxying between them can really amplify TCP

Ensure that the upstream is always queried, so that if upstream is going
to NXDOMAIN natc will also return NXDOMAIN rather than returning address
allocations.
At this time both IPv4 and IPv6 are still returned if upstream has a
result, regardless of upstream support - this is ~ok as we're proxying.
Rewrite the tests to be once again slightly closer to integration tests,
but they're still very rough and in need of a refactor.
Further refactors are probably needed implementation side too, as this
removed rather than added units.

This adds netx.DialFunc, unifying a type we have a bazillion other
places, giving it now a nice short name that's clickable in
editors, etc.
That highlighted that my earlier move (03b47a55c7956) of stuff from
nettest into netx moved too much: it also dragged along the memnet
impl, meaning all users of netx.DialFunc who just wanted netx for the
type definition were instead also pulling in all of memnet.
So move the memnet implementation netx.Network into memnet, a package
we already had.
Then use netx.DialFunc in a bunch of places. I'm sure I missed some.
And plenty remain in other repos, to be updated later.

In this PR, we update ipnlocal.LocalBackend to allow registering callbacks for control client creation
and profile changes. We also allow to register ipnauth.AuditLogFunc to be called when an auditable
action is attempted.
We then use all this to invert the dependency between the auditlog and ipnlocal packages and make
the auditlog functionality optional, where it only registers its callbacks via ipnlocal-provided hooks
when the auditlog package is imported.
We then underscore-import it when building tailscaled for Windows, and we'll explicitly
import it when building xcode/ipn-go-bridge for macOS. Since there's no default log-store
location for macOS, we'll also need to call auditlog.SetStoreFilePath to specify where
pending audit logs should be persisted.

The default values for `tailscale up` and `tailscale set` are supposed
to agree for all common flags. But they don’t for `--accept-routes`
on Windows and from the Mac OS App Store, because `tailscale up`
computes this value based on the operating system:
user@host:~$ tailscale up --help 2>&1 | grep -A1 accept-routes
--accept-dns, --accept-dns=false
accept DNS configuration from the admin panel (default true)
user@host:~$ tailscale set --help 2>&1 | grep -A1 accept-routes
--accept-dns, --accept-dns=false
accept DNS configuration from the admin panel
Luckily, `tailscale set` uses `ipn.MaskedPrefs`, so the default values
don’t logically matter. But someone will get the wrong idea if they
trust the `tailscale set --help` documentation.
In addition, `ipn.Prefs.RouteAll` defaults to true so it disagrees
with both of the flags above.
This patch makes `--accept-routes` use the same logic for in both
commands by hoisting the logic that was buried in `cmd/tailscale/cli`
to `ipn.Prefs.DefaultRouteAll`. Then, all three of defaults can agree.
