- update to 1.4
    - v1.4 kadmin client requires a v1.4 kadmind on the server, or use the "-O"
        flag to specify that it should communicate with the server using the
        older protocol
    - new libkrb5support library
    - v5passwdd and kadmind4 are gone
    - versioned symbols
    - pick up $KRB5KDC_ARGS from /etc/sysconfig/krb5kdc, if it exists, and pass
        it on to krb5kdc
    - pick up $KADMIND_ARGS from /etc/sysconfig/kadmin, if it exists, and pass
        it on to kadmind
    - pick up $KRB524D_ARGS from /etc/sysconfig/krb524, if it exists, and pass
        it on to krb524d *instead of* "-m"
    - set "forwardable" in [libdefaults] in the default krb5.conf to match the
        default setting which we supply for pam_krb5
    - set a default of 24h for "ticket_lifetime" in [libdefaults], reflecting
        the compiled-in default
