pam-krb5 2.4

The main changes in this version are again Heimdal compilation fixes, but I also refactored the code to parse options and extract information from krb5.conf to make it much more readable. Error logging has also been improved, and pam-krb5 now complains about unknown options in the PAM configuration, which will hopefully make it easier to catch typos.

There are a few new features I want to add (my TODO file for the package is small enough it's tempting to knock everything off of it), but that will have to wait until after vacation. I don't want to do a lot of feature development right before the Debian freeze.

You can get the latest version from the pam-krb5 distribution page.
