Ticket History #2772: krb4 APIs do not honor dns_fallback libdefault

The krb4 APIs do not honor dns_fallback libdefault. For example, krb_get_krbhst() makes dns
SRV record requests regardless of the value of dns_fallback in the libdefaults section of the
configuration file.

This is a problem if the reason you are trying to use "dns_fallback = no" is to avoid using a
busted res_ninit() .... :-)

* include/k5-int.h (struct _krb5int_access): Add function pointer field
use_dns_kdc.
* lib/krb5/os/accessor.c (krb5int_accessor): Set new field use_dns_kdc.
* lib/krb4/RealmsConfig-glue.c (krb_get_krbhst): Check if DNS should be used
for getting KDC names before actually using it.
