The ftp daemon dups the control socket to stdin and uses that fd throughout the code. Clarify this usage slightly by changing from explicit use of "0" for the fd to a variable, to make it clear what the zero represents in the non-blacklist code. Make the blacklist_notify routine use STDIN_FILENO so as to have less of a "magic number" feel to the code.
