For users that hold a reference to a pidfd procfs might not even be available nor is it desirable to parse through procfs just for the sake of getting namespace file descriptors for a process. Make it possible to directly retrieve namespace file descriptors from a pidfd. Pidfds already can be used with setns() to change a set of namespaces atomically.
