Please rebase against upstream

[jperkin]

This fork is a little behind upstream, and in particular is missing 42ec952 which will hopefully fix the build against Go 1.21.

Go 1.21 is now the default in pkgsrc, and this causes wireguard-go to fail in gvisor:

https://us-central.manta.mnx.io/pkgsrc/public/reports/trunk/tools/20231031.0849/wireguard-go-0.0.20220316/build.log

due to the following constraints in gvisor@v0.0.0-20221203005347-703fd9b7fbc0/pkg/gohacks/gohacks_unsafe.go:

//go:build go1.13 && !go1.21
// +build go1.13,!go1.21

Thanks!

A quick-and-dirty rebase of https://github.com/nshalman/wireguard-go/tree/tailscale-1.40
is up at

https://github.com/nshalman/wireguard-go/tree/20231031
98037d6

I need to do some testing to see if it's working correctly.

It seems off.

[jperkin]

Just to confirm that this builds fine, but if it's off then I'll wait for your ok before committing.

I don't know what was wrong with that branch, but I rebased against a release tag from upstream and that seems to behave. Please try https://github.com/nshalman/wireguard-go/releases/tag/0.0.20230223-sunos
