darwin: Assign host address to the utun and route vpn explicitly ( #1931 )
...
Tailscale with an exit node treats every interface address prefix as an
attached LAN and either claims it or excludes it, and configd then rewrites
the matching route away from nebula's utun. Interfaces holding a single
address are skipped, so assign /32 and /128 and add the network route
ourselves for both families.

Let the darwin tun adopt an fd the host already configured ( #1890 )
...
newTunFromFd was a stub on darwin, so an embedder handed a utun by the OS had
no way to use it. A darwin network extension is given exactly that:
NEPacketTunnelProvider creates the device and applies addressing, mtu and
routes from its network settings, and a sandboxed extension cannot change them
afterwards. Adopting that fd means everything about moving packets is shared
with newTun and only the setup differs, so the tun tracks whether the host owns
it and leaves the system routing table and interface config alone when it does.

* upgrade to yaml.v3
The main nice fix here is that maps unmarshal into `map[string]any`
instead of `map[any]any`, so it cleans things up a bit.
* add config.AsBool
Since yaml.v3 doesn't automatically convert yes to bool now, for
backwards compat

fix unsafe routes darwin ( #610 )
...
With Nebula 1.4.0, if you create an unsafe_route that has a collision with an existing route on the system, the unsafe_route will be silently dropped (and the existing system route remains).
With Nebula 1.5.0, this same situation will cause Nebula to fail to start with an error (EEXIST).
This change restores the Nebula 1.4.0 behavior (but with a WARN log as well).

fix makeRouteTree allowMTU ( #611 )
...
With the previous implementation, we check if route.MTU is greater than zero,
but it will always be because we set it to the default MTU in
parseUnsafeRoutes. This change leaves it as zero in parseUnsafeRoutes so
it can be examined later.
