parseopt: add OPT_NOOP_NOARG
Add OPT_NOOP_NOARG, a helper macro to define deprecated options in a standard way. The help text is taken from the no-op option -r of git revert. The callback could be made to emit a (conditional?) warning later. And we could also add OPT_NOOP (requiring an argument) etc. as needed.
