This fixes an infinite loop caused by the configuration of
systemd-resolved on Amazon Linux 2023 and how that interacts with
Tailscale's "direct" mode. We now drop the Tailscale service IP from the
OS's "base configuration" when we detect this configuration.

This package uses a count-min sketch and a heap to track the top K items
in a stream of data. Tracking a new item and adding a count to an
existing item both require no memory allocations and is at worst
O(log(k)) complexity.

Looking at profiles, we spend a lot of time in winipcfg.LUID.DeleteRoute
looking up the routing table entry for the provided RouteData.
But we already have the row! We previously obtained that data via the full
table dump we did in getInterfaceRoutes. We can make this a lot faster by
hanging onto a reference to the wipipcfg.MibIPforwardRow2 and executing
the delete operation directly on that.

* tsweb: update ServeMux matching to 1.22.0 syntax
Updates #cleanup
Go 1.22.0 introduced the ability to use more expressive routing patterns
that include HTTP method when constructing ServeMux entries.
Applications that attempted to use these patterns in combination with
the old `tsweb.Debugger` would experience a panic as Go would not permit
the use of matching rules with mixed level of specificity. We now
specify the method for each `/debug` handler to prevent
incompatibilities.

* cmd/k8s-operator,k8s-operator: introduce proxy configuration mechanism via ProxyClass custom resource.
ProxyClass custom resource can be used to specify customizations
for the proxy resources created by the operator.
Add a reconciler that validates ProxyClass resources
and sets a Ready condition to True or False with a corresponding reason and message.
This is required because some fields (labels and annotations)
require complex validations that cannot be performed at custom resource apply time.
Reconcilers that use the ProxyClass to configure proxy resources are expected to
verify that the ProxyClass is Ready and not proceed with resource creation
if configuration from a ProxyClass that is not yet Ready is required.
If a tailscale ingress/egress Service is annotated with a tailscale.com/proxy-class annotation, look up the corresponding ProxyClass and, if it is Ready, apply the configuration from the ProxyClass to the proxy's StatefulSet.
If a tailscale Ingress has a tailscale.com/proxy-class annotation
and the referenced ProxyClass custom resource is available and Ready,
apply configuration from the ProxyClass to the proxy resources
that will be created for the Ingress.
Add a new .proxyClass field to the Connector spec.
If connector.spec.proxyClass is set to a ProxyClass that is available and Ready,
apply configuration from the ProxyClass to the proxy resources created for the Connector.
Ensure that when Helm chart is packaged, the ProxyClass yaml is added to chart templates. Ensure that static manifest generator adds ProxyClass yaml to operator.yaml. Regenerate operator.yaml

FileSystemForLocal was listening on the node's Tailscale address,
which potentially exposes the user's view of TailFS shares to other
Tailnet users. Remote nodes should connect to exported shares via
the peerapi.
This removes that code so that FileSystemForLocal is only avaialable
on 100.100.100.100:8080.

The new math/rand/v2 package includes an m-local global random number
generator that can not be reseeded by the user, which is suitable for
most uses without the RNG pools we have in a number of areas of the code
base.
The new API still does not have an allocation-free way of performing a
seeded operations, due to the long term compiler bug around interface
parameter escapes, and the Source interface.
This change introduces the two APIs that math/rand/v2 can not yet
replace efficiently: seeded Perm() and Shuffle() operations. This
implementation chooses to use the PCG random source from math/rand/v2,
as with sufficient compiler optimization, this source should boil down
to only two on-stack registers for random state under ideal conditions.

authURLs returned by control expire after 1 hour from creation. Customer reported that the Tailscale client on macOS would sending users to a stale authentication page when clicking on the `Login...` menu item. This can happen when clicking on Login after leaving the device unattended for several days. The device key expires, leading to the creation of a new authURL, however the client doesn't keep track of when the authURL was created. Meaning that `login-interactive` would send the user to an authURL that had expired server-side a long time before.
This PR ensures that whenever `login-interactive` is called via LocalAPI, an authURL that is too old won't be used. We force control to give us a new authURL whenever it's been more than 30 minutes since the last authURL was sent down from control.

The new read-only mode is only accessible when running `tailscale web`
by passing a new `-readonly` flag. This new mode is identical to the
existing login mode with two exceptions:
- the management client in tailscaled is not started (though if it is
already running, it is left alone)
- the client does not prompt the user to login or switch to the
management client. Instead, a message is shown instructing the user
to use other means to manage the device.

* cmd/containerboot,cmd/k8s-operator/deploy/manifests: optionally forward cluster traffic via ingress proxy.
If a tailscale Ingress has tailscale.com/experimental-forward-cluster-traffic-via-ingress annotation, configure the associated ingress proxy to have its tailscale serve proxy to listen on Pod's IP address. This ensures that cluster traffic too can be forwarded via this proxy to the ingress backend(s).
In containerboot, if EXPERIMENTAL_PROXY_CLUSTER_TRAFFIC_VIA_INGRESS is set to true
and the node is Kubernetes operator ingress proxy configured via Ingress,
make sure that traffic from within the cluster can be proxied to the ingress target.
