attempting to mark up 32 bit error codes, needed for NT domains.

separated out smb server-mode password validation into a separate file.
added called and calling netbios names to client gen state: referenced
section in rfc1002.txt.
created workstation trust account checking code in ntclient.c

there might be a bug in reply_session_setup_andX.  i indented and added { }
around single-line if statements: the lm password checking code now doesn't
look right (around the GUEST_SESSSETUP bits).  *no code semantics have been
changed by the indentation process*.
