parseopt: add OPT_NOOP_NOARG

Browse Source 
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.
