libsmb/smbdes.c: #ifdef'ed out code prior to removal.

rpc_client/cli_pipe.c: Inlined code removed from smbdes.c
rpc_server/srv_samr.c: Fixed unused variable warning.
rpc_server/srv_util.c: Inlined code removed from smbdes.c

Luke - the above changes are the first part of the changes
you and I discussed as being neccessary at the CIFS conference.
*PLEASE REVIEW THESE CHANGES* - make sure I haven't broken
any of the authenticated DCE/RPC code.

smbd/nttrans.c: Fixed to allow NT5.0beta2 to use Samba shares
                with NT SMB support.
smbd/open.c: Fixed mkdir when called from nttrans calls.
smbd/server.c: Set correct size for strcpy of global_myworkgroup.

Jeremy.
