7652512976 - Added support for passive mode FTP by aliasing 227 replies.
It does mean that it is now possible to run passive-mode FTP
  server behind NAT.

- SECURITY: FTP aliasing engine now ensures that:
  o the segment preceding a PORT/227 segment terminates with a \r\n;
  o the IP address in the PORT/227 matches the source IP address of
    the packet;
  o the port number in the PORT command or 277 reply is greater than
    or equal to 1024.

3b160b8b6e Create the alias library. This is currently only used by
ppp (or will be shortly).  Natd can now be updated to use
this library rather than carrying its own version of the code.
