r10337: This grubby little hack is the implementation of a concept discussed
on the kerberos mailing lists a couple of weeks ago: Don't use DNS at
all for expanding short names into long names.
Using the 'override krb5_init_context' code already in the tree, this
removes the DNS lag on a kerberos session setup/connection.
