kadmin-remctl 2.3

I had intended for the examine command of kadmin-backend to let one see any Kerberos principal (at least that doesn't have a very strange name), but I'd messed up the code. I fixed it (after messing it up first in a different way) in this release, and now you can examine most principals even if that instance isn't otherwise managed. While I was there, I also improved the Kerberos v5 to Kerberos v4 principal conversion for examine, even though that code is frozen.

This release also has improved versions of my Autoconf macros for remctl, GSS-API, and Kerberos library detection, even though this package doesn't really need it. I wanted to do something else to improve the package since I was doing a release anyway.

You can get the latest version from the kadmin-remctl distribution page.
