        these routines provide a way of transferring the information
        in the "header" structure between machines.
        Programs calling these routines either read or write
        their information into the header structure.
        These procedures format the info in a way that is acceptable.
        Called by net.c, netdaemon.c, and netq.c.

        generate a variable parameter list
        the format is:
                (name value, name value, ..., name value)
        where names are unquoted single words and values
        are unquoted if a single alphanumeric word, and are
        surrounded by {} otherwise. \ quotes { and }.
        the values are escape-processed, e.g. \n becomes 012.
        this function returns such a list.
        Returns the null parm list if nothing to give, i.e. "()"

        Should also default so single keywords can have on/off
        states, and so do not require a value.

        Things this variable protocol should specify:
                EPASSWD         encrypted passwd
                FILEMODE        file mode
                FROMUID         from users' uid
                FROMGID         from users' gid
                COMPRESS        use colin's compression
                ACCTPAIR        handle acct pairs
                MESSAGEID       unique number identifying this request.
                FILENAME        when omitted by netcp, will use FILENAME ext.
                REPLYTO         the person the response should be sent to

                 --- possibly ---
                MACHINE2        a second machine (e.g. 3way netcp)
                LOGIN2          a second login name
                PASSWD2         a second passwd
