lib/util_unistr.c:

        rewrote unistr2_to_ascii() to correct a bug seen on SGI boxes.

rpc_parse/parse_misc.c:
rpc_parse/parse_prs.c:
        rewrote of BUFFER5 handling to NOT byteswap when it was already in
        network byte order.

rpc_parse/parse_samr.c:
        cleanup of samr_io_q_lookup_domain(), remove the over-parsing by 2
        bytes.

rpc_server/srv_lsa.c:
        UNISTR2 strings need to be NULL terminated to pleased W2K.

rpc_server/srv_spoolss_nt.c:
        use snprintf instead of safe_strcpy as we want the string
        truncated at 32 chars.


That should fix SUN and SGI box not able to act as printserver and the
problem with joining from a W2K wks.

        J.F.
