MIT Kerberos support in Windows builds

Just a heads-up really - following discussion with Magnus and other
people involved in building our Windows packages, I intend to stop
including MIT Kerberos support from 9.0 onwards. This is largely due
to the fact that most (maybe all) users are more likely to use SSPI on
Windows, and more importantly, due to the lack of timely releases of
the Kerberos for Windows builds, as noted here:
