These patches do some gssd code clean-up and change the way keytabs are
selected to obtain machine credentials.

1) adds missing newlines to some seldom printed error messages
2) fixes a memory leak in the error path of limit_krb5_enctypes()
3) adds some macros to clean up differences between MIT and Heimdal interfaces
4) adds the new functions that change the way keytabs are selected.
   the new behavior is to search for particular keytab entries in a
   specified order:

   root/<fqdn>@<REALM>
   nfs/<fqdn>@<REALM>
   host/<fqdn>@<REALM>
   root/<any-name>@<REALM>
   nfs/<any-name>@<REALM>
   host/<any-name>@<REALM>

5) actually use the new functions added in the previous patch
6) does some cleanup in gssd_get_single_krb5_cred() and improves
   the debugging messages
7) removes the now obsolete routines
8) adds a debug message to indicate processing is beginning
