86aa0485a6 ipn/ipnlocal, util/syspolicy: make run exit node a preference option
Previously, the "RunExitNode" policy merely controlled the visibility of
the "run as exit node" menu item, not the setting itself. This migrates
that setting to a preference option named "AdvertiseExitNode".

f706a3abd0 ipn/ipnlocal, util/syspolicy: add auto update policy
Due to the Sparkle preference naming convention, macsys already has a
policy key named "ApplyUpdates" that merely shows or hides the menu
item that controls if auto updates are installed, rather than directly
controlling the setting.

For other platforms, we are going to use "InstallUpdates" instead
because it seemed better than the other options that were considered.

af32d1c120 ipn/ipnlocal: better enforce system policies
Previously, policies affected the default prefs for a new profile, but
that does not affect existing profiles. This change ensures that
policies are applied whenever preferences are loaded or changed, so a
CLI or GUI client that does not respect the policies will still be
overridden.

Exit node IP is dropped from this PR as it was implemented elsewhere
in #10172.

2dc0645368 ipn/ipnlocal,cmd/tailscale: persist tailnet name in user profile
This PR starts to persist the NetMap tailnet name in SetPrefs so that tailscaled
clients can use this value to disambiguate fast user switching from one tailnet
to another that are under the same exact login. We will also try to backfill
this information during backend starts and profile switches so that users don't
have to re-authenticate their profile. The first client to use this new
information is the CLI in 'tailscale switch -list' which now uses text/tabwriter
to display the ID, Tailnet, and Account. Since account names are ambiguous, we
allow the user to pass 'tailscale switch ID' to specify the exact tailnet they
want to switch to.

Now that 1.54 has released, and the new web client will be included in
1.56, we can remove the need for the node capability. This means that
all 1.55 unstable builds, and then eventually the 1.56 build, will work
without setting the node capability.

The web client still requires the "webclient" user pref, so this does
NOT mean that the web client will be on by default for all devices.

3496d62ed3 ipn/ipnlocal: add empty address to the app-connector localNets set
App connectors handle DNS requests for app domains over PeerAPI,
but a safety check verifies the requesting peer has at least permission
to send traffic to 0.0.0.0:53 (or 2000:: for IPv6) before handling the DNS
request. The correct filter rules are synthesized by the coordination server
and sent down, but the address needs to be part of the 'local net' for the
filter package to even bother checking the filter rules, so we set them here.

if the user pref and nodecap for the new web client are enabled, serve
the client over requests to 100.100.100.100.  Today, that is just a
static page that lists the local Tailcale IP addresses.

For now, this will render the readonly full management client, with an
"access" button that sends the user through check mode.  After
completing check mode, they will still be in the read-only view, since
they are not accessing the client over Tailscale.

Instead, quad100 should serve the lobby client that has a "manage"
button that will open the management client on the Tailscale IP (and
trigger check mode). That is something we'll fix in a subsequent PR in
the web client code itself.

95671b71a6 ipn, safesocket: use Windows token in LocalAPI
On Windows, the idiomatic way to check access on a named pipe is for
the server to impersonate the client on its current OS thread, perform
access checks using the client's access token, and then revert the OS
thread's access token back to its true self.

The access token is a better representation of the client's rights than just
a username/userid check, as it represents the client's effective rights
at connection time, which might differ from their normal rights.

This patch updates safesocket to do the aforementioned impersonation,
extract the token handle, and then revert the impersonation. We retain
the token handle for the remaining duration of the connection (the token
continues to be valid even after we have reverted back to self).

Since the token is a property of the connection, I changed ipnauth to wrap
the concrete net.Conn to include the token. I then plumbed that change
through ipnlocal, ipnserver, and localapi as necessary.

I also added a PermitLocalAdmin flag to the localapi Handler which I intend
to use for controlling access to a few new localapi endpoints intended
for configuring auto-update.
