rpc_client/cli_lsarpc.c:

rpc_parse/parse_lsa.c:
nsswitch/winbindd_rpc.c:
nsswitch/winbindd.h:
 - Add const

libads/ads_ldap.c:
-  Add ads_sid_to_dn utility function

nsswitch/winbindd_ads.c:
 - Use new utility function ads_sid_to_dn
 - Don't search for 'dn=', rather call the ads_search_retry_dn()

nsswitch/winbindd_ads.c:
include/rpc_ds.h:
rpc_client/cli_ds.c:
 - Fixup braindamage in cli_ds_enum_domain_trusts():
    - This function was returning a UNISTR2 up to the caller, and
      was doing nasty (invalid, per valgrind) things with memcpy()
    - Create a new structure that represents this informaiton in a useful way
      and use talloc.
