* Fix some problems with building the Kerberos IV and 5 mechs.
* Made the port to optionally not build the mechs, define
* The Kerberos IV case is special, as we can use the base kerberos 4x
(<=5.0-RELEASE), or use the security/krb4 port.
WITH_KERBEROS4 - use security/krb4 port
if <=5.0-RELEASE, use krb4 port only if /usr/lib/libkrb.a
WITHOUT_KERBEROS4 - disables using the base systems /usr/lib/libkrb.a
(<=5.0), if it exists and MAKE_KERBEROS4 defined in /etc/make.conf
* Changed the combined rcNG/rcOG scripts, so that the defaults are at the top
of the rc.d script and not in an external file to the script.
