New version of CVS access control patch available

[minyard]

I have ported the access control patch to the newest verson of CVS,
fixed some bugs, and added some new features.  It's available on my
web page at http://members.home.net/minyard.

The access control path adds per-directory access control lists to CVS
(pserver) and the ability to do full user management (password
changing, adding/deleting users) from the CVS command line.  It's
certainly not perfect, but it does a pretty good job.  If someone
(maybe me) adds an SSL implmentation based on this, it would be pretty
secure.

This release adds:
* Lots of bug fixes and cleanups.  The new CVS directory/repository
  stuff was cleaned up and made much better, this cleaned up some of
  my patch.
* The ability to specify a prefix for the repository that the server
  will tack on to the beginning of the root directory.  So if your
  repository is in /home/cvs/root, you can set the prefix to /home/cvs
  and the clients will only need to specify :pserver:address@hidden:/root.  
Plus,
  you can move the repository on the server's filesystem without
  affecting the users.
* For the access permissions, you can optionally allow them to
  propigate to subdirectories.  I don't personally like this very
  much, but a lot of other people do, so I added it.

If you use this patch, an upgrade is highly recommended.
