auth/auth_util.c:

- Fill in the 'backup' idea of a domain, if the DC didn't supply one.  This
   doesn't seem to occour in reality, hence why we missed the typo.

lib/charcnv.c:
lib/smbldap.c:
libads/ldap.c:
libsmb/libsmbclient.c:
printing/nt_printing.c:
 - all the callers to pull_utf8_allocate() pass a char ** as the first
   parammeter, so don't make them all cast it to a void **

nsswitch/winbind_util.c:
 - Allow for a more 'correct' view of when usernames should be qualified
   in winbindd.  If we are a PDC, or have 'winbind trusted domains only',
   then for the authentication returns stip the domain portion.
 - Fix valgrind warning about use of free()ed name when looking up our
   local domain.  lp_workgroup() is maniplated inside a procedure that
   uses it's former value.  Instead, use the fact that our local domain is
   always the first in the list.
