It also updates nrptRuleDatabase to use the new package instead of its own gpNotificationWatcher implementation.

While `clientupdate.Updater` won't be able to apply updates on macsys,
we use `clientupdate.CanAutoUpdate` to gate the EditPrefs endpoint in
localAPI. We should allow the GUI client to set AutoUpdate.Apply on
macsys for it to properly get reported to the control plane. This also
allows the tailnet-wide default for auto-updates to propagate to macsys
clients.

cmd/k8s-operator,ssh/tailssh,tsnet: optionally record kubectl exec sessions
The Kubernetes operator's API server proxy, when it receives a request
for 'kubectl exec' session now reads 'RecorderAddrs', 'EnforceRecorder'
fields from tailcfg.KubernetesCapRule.
If 'RecorderAddrs' is set to one or more addresses (of a tsrecorder instance(s)),
it attempts to connect to those and sends the session contents
to the recorder before forwarding the request to the kube API
server. If connection cannot be established or fails midway,
it is only allowed if 'EnforceRecorder' is not true (fail open).

The DERP Return Path Optimization (DRPO) is over four years old (and
on by default for over two) and we haven't had problems, so time to
remove the emergency shutoff code (controlknob) which we've never
used. The controlknobs are only meant for new features, to mitigate
risk. But we don't want to keep them forever, as they kinda pollute
the code.

cmd/containerboot,cmd/k8s-operator: enable IPv6 for fqdn egress proxies
Don't skip installing egress forwarding rules for IPv6 (as long as the host
supports IPv6), and set headless services `ipFamilyPolicy` to
`PreferDualStack` to optionally enable both IP families when possible. Note
that even with `PreferDualStack` set, testing a dual-stack GKE cluster with
the default DNS setup of kube-dns did not correctly set both A and
AAAA records for the headless service, and instead only did so when
switching the cluster DNS to Cloud DNS. For both IPv4 and IPv6 to work
simultaneously in a dual-stack cluster, we require headless services to
return both A and AAAA records.
If the host doesn't support IPv6 but the FQDN specified only has IPv6
addresses available, containerboot will exit with error code 1 and an
error message because there is no viable egress route.

This change expands the `exit-node list -filter` command to display all
location based exit nodes for the filtered country. This allows users
to switch to alternative servers when our recommended exit node is not
working as intended.
This change also makes the country filter matching case insensitive,
e.g. both USA and usa will work.

High severity health warning = a system notification will appear, which can be quite disruptive to the user and cause unnecessary concern in the event of a temporary network issue.
Per design decision (@sonovawolf), the severity of all warnings but "network is down" should be tuned down to medium/low. ImpactsConnectivity should be set, to change the icon to an exclamation mark in some cases, but without a notification bubble.
I also tweaked the messaging for update-available, to reflect how each platform gets updates in different ways.

Fix regression from #8108 (Mar 2023). Since that change, gocross has
always been rebuilt on each run of ./tool/go (gocross-wrapper.sh),
adding ~100ms. (Well, not totally rebuilt; cmd/go's caching still
ends up working fine.)
The problem was $gocross_path was just "gocross", which isn't in my
path (and "." isn't in my $PATH, as it shouldn't be), so this line was
always evaluating to the empty string:
gotver="$($gocross_path gocross-version 2>/dev/null || echo '')"
The ./gocross is fine because of the earlier `cd "$repo_root"`

Detection of duplicate Network Lock signature chains added in
01847e0123 failed to account for chains
originating with a SigCredential signature, which is used for wrapped
auth keys. This results in erroneous removal of signatures that
originate from the same re-usable auth key.
This change ensures that multiple nodes created by the same re-usable
auth key are not getting filtered out by the network lock.
