  Modified files:
    lib/libalias         alias_db.c alias_ftp.c alias_local.h 
  Log:
  - 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.
