  Log:
  MFC of jail fixes regarding INADDR_LOOPBACK.  -CURRENT commit message:
  
    Anton kindly pointed out (and fixed) a bug in the Jail handling of the
    bind() call on IPv4 sockets:
  
      Currently, if one tries to bind a socket using INADDR_LOOPBACK inside a
      jail, it will fail because prison_ip() does not take this possibility
      into account.  On the other hand, when one tries to connect(), for
      example, to localhost, prison_remote_ip() will silently convert
      INADDR_LOOPBACK to the jail's IP address.  Therefore, it is desirable to
      make bind() to do this implicit conversion as well.
  
      Apart from this, the patch also replaces 0x7f000001 in
      prison_remote_ip() to a more correct INADDR_LOOPBACK.
