Previously: *036f70b7b4for linux *35bee36549for windows This does macOS. And removes all the compat code for the old style. (e.g. iOS, js are no longer mentioned; all platforms without implementations just default to not doing anything) One possible regression is that platforms without explicit implementations previously tried to do the "netstat -na" style to get open ports (but not process names). Maybe that worked on FreeBSD and OpenBSD previously, but nobody ever really tested it. And it was kinda useless without associated process names. So better off removing those for now until they get a good implementation. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>
