This is a fork of wireguard-windows's firewall package, with
the firewall rules adjusted to better line up with tailscale's
needs.
The package was taken from commit 3cc76ed5f222ec82748ef3bd8c41d4b059e28cdb
in our fork of wireguard-go.

Gets it out of wgengine so the Engine isn't responsible for being a
callback registration hub for it.
This also removes the Engine.LinkChange method, as it's no longer
necessary. The monitor tells us about changes; it doesn't seem to
need any help. (Currently it was only used by Swift, but as of
14dc790137 we just do the same from Go)

And add a --socks5-server flag.
And fix a race in SOCKS5 replies where the response header was written
concurrently with the copy from the backend.

Previously tailscaled on macOS was running "/sbin/route monitor" as a
child process, but child processes aren't allowed in the Network
Extension / App Store sandbox. Instead, just do what "/sbin/route monitor"
itself does: unix.Socket(unix.AF_ROUTE, unix.SOCK_RAW, 0) and read that.
We also parse it now, but don't do anything with the parsed results yet.
We will over time, as we have with Linux netlink messages over time.
Currently any message is considered a signal to poll and see what changed.

Currently it assumes exactly 1 registered callback. This changes it to
support 0, 1, or more than 1.
This is a step towards plumbing wgengine/monitor into more places (and
moving some of wgengine's interface state fetching into monitor in a
later step)

UIs need to see the full unedited netmap in order to know what exit nodes they

* move probing out of netcheck into new net/portmapper package
* use PCP ANNOUNCE op codes for PCP discovery, rather than causing
short-lived (sub-second) side effects with a 1-second-expiring map +
delete.
* track when we heard things from the router so we can be less wasteful
in querying the router's port mapping services in the future
* use portmapper from magicsock to map a public port

Importing the non-main package was missing some dependencies that
"go mod tidy" would then cleanup. Also added a non-ignore build tag to
avoid other tools getting upset about importing a main package.

"go mod tidy" did some unrelated work in go.sum, maybe because it was
not run with Go 1.16 before.
