Switch from sync.Once to sync.OnceFunc and sync.OnceValues. Keep Root a function (rather than a variable) because godoc renders function doc better than a variable doc. Switch to using internal function root internally. Modify tests accordingly (and simplify NewIntelRdtTestUtil to fakeRoot). Signed-off-by: Kir Kolyshkin <kolyshkin@gmail.com>
