Title: Only warn once when the deprecation warning wrapper is called multiple times

In response to https://github.com/joyent/node/commit/5403a8ce4cce83a13569b09ee5b2ba3d1ad8c176#commitcomment-913323

If a reference to the deprecation warning wrapper is kept and used it warns every time. This adds a flag so that the previous behavior of only ever warning once is followed in all circumstances.
