[patch] krb5_get_host_realm could try harder to get a default fqdn

[Michael B Allen <mba2000@ioplex.com>]

Hi Love,

Attached is a patch to lib/krb5/get_host_realm.c that replaces the call
to gethostname in krb5_get_host_realm with a call to a new function
dns_get_default_fqdn that calls gethostname and then, if necessary,
gethostbyname. Basically it tries harder to find a default domain name.

My problem case is Debian Linux which, by default, sets the hostname
to a non-FQDN name. And querying gethostbyname returns a name with a
'.' at the end:

# hostname
ubuntu32

# hostname --fqdn
ubuntu32.example.com.

Please consider this patch for inclusion in Heimdal.

Mike
