windows/svc: rewrite in Go
The old service management code was written in assembly and communicated
over Windows events, which resulted in non-obvious control flow.
NewCallback makes it possible to rewrite all of this in vanilla Go. This
also enables the service test on the Go builders, as modifying system
services shouldn't be an issue there.
