NT4 sp4, anyone working on it?

[Luke Kenneth Casson Leighton]

ok, the fix to get NT SP4 to talk to samba is really simple, and has been
confirmed as working, by tim winders (ta, tim!).  so, it looks like NT SP4
code is a little more robust (hooray).

in ipc.c, search for make_rpc_hdr:

    /***/
	/*** then do the header, now we know the length ***/
    /***/

	make_rpc_hdr(&p->hdr, RPC_BINDACK, RPC_FLG_FIRST | RPC_FLG_LAST,
				 p->hdr.call_id,
	             p->rdata.offset + p->rauth.offset + 0x10,
	                                               ^^^^^^
	             p->rauth.offset);

	smb_io_rpc_hdr("", &p->hdr, &p->rhdr, 0);
	mem_realloc_data(p->rhdr.data, p->rdata.offset);
