Change in cvsps maintainership, abd a --fast-export option

Earlier today David Mansfield handed off to me the cvsps project. This
is the code used as an engine for reading CVS repositories by
git-cvsimport.

His reason (aside from general overwork and no longer having a strong
interest on the code) is that I have added a --fast-export option to
cvsps-3.0 that emits a git fast-import stream representing the CVS
history.
 
I did this so that reposurgeon could use cvsps as a front end.  But I
expect it will be of some interest to whoever is maintaining
git-cvsimport. That code can now become much, *much* smaller and
simpler.

The new --fast-export mode solves at least one bug mentioned on the
git-cvsimport man page; multiple tags pointing at the same CVS changeset
will be passed through correctly.

Possibly it fixes some other problems described there as well.  
I don't understand all the bug warnings on that page and would like to
discuss them with the author, whoever that is.  Possibly cvsps can be
further enhanced to address these problems; I'm willing to work on that.
