Remove fybrik.io/crdoc dependency as it is causing issues for folks attempting
to vendor tailscale using GOPROXY=direct.
This means that the CRD API docs in ./k8s-operator/api.md will no longer
be generated- I am going to look at replacing it with another tool
in a follow-up.

Windows requires routes to have a nexthop. Routes created using the interface's local IP address or an unspecified IP address ("0.0.0.0" or "::") as the nexthop are considered on-link routes. Notably, Windows treats on-link subnet routes differently, reserving the last IP in the range as the broadcast IP and therefore prohibiting TCP connections to it, resulting in WSA error 10049: "The requested address is not valid in its context. This does not happen with single-host routes, such as routes to Tailscale IP addresses, but becomes a problem with advertised subnets when all IPs in the range should be reachable.
Before Windows 8, only routes created with an unspecified IP address were considered on-link, so our previous approach of using the interface's own IP as the nexthop likely worked on Windows 7.
This PR updates configureInterface to use the TailscaleServiceIP (100.100.100.100) and its IPv6 counterpart as the nexthop for subnet routes.

With this change, the error handling and request logging are all done in defers
after calling inner.ServeHTTP. This ensures that any recovered values which we
want to re-panic with retain a useful stacktrace. However, we now only
re-panic from errorHandler when there's no outside logHandler. Which if you're
using StdHandler there always is. We prefer this to ensure that we are able to
write a 500 Internal Server Error to the client. If a panic hits http.Server
then the response is not sent back.

StdHandler/retHandler would previously emit one log line for each request.
If there were multiple StdHandler in the chain, there would be one log line
per instance of retHandler.
With this change, only the outermost StdHandler/logHandler actually logs the
request or invokes OnStart or OnCompletion callbacks. The error-rendering part
of retHandler lives on in errorHandler, and errorHandler passes those errors up
the stack to logHandler through a callback that logHandler places in the
request.Context().

We were printing some leftover debug logs within a callback function that would be executed after the test completion, causing the test to fail. This change drops the log calls to address the issue.

If we get an non-disco presumably-wireguard-encrypted UDP packet from
an IP:port we don't recognize, rather than drop the packet, give it to
WireGuard anyway and let WireGuard try to figure out who it's from and
tell us.
This uses the new hook added in https://github.com/tailscale/wireguard-go/pull/27

Some operations cannot be implemented with the prior API:
* Iterating over the map and deleting keys
* Iterating over the map and replacing items
* Calling APIs that expect a native Go map
Add a Map.WithLock method that acquires a write-lock on the map
and then calls a user-provided closure with the underlying Go map.
This allows users to interact with the Map as a regular Go map,
but with the gaurantees that it is concurrent safe.

This adds support for generic types and interfaces to our cloner and viewer codegens.
It updates these packages to determine whether to make shallow or deep copies based
on the type parameter constraints. Additionally, if a template parameter or an interface
type has View() and Clone() methods, we'll use them for getters and the cloner of the
owning structure.

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).
