ioctl translation preliminary patch

[Richard Henderson]

Is the change in termios extension compatible with what the kernel
accepts now?  I.e. all the new stuff is at the end?  If so, just
take the approach Sparc did:

/* Oh well, this is necessary since the kernel data structure is
   different from the user-level version.  */
#undef  TCGETS
#undef  TCSETS
#undef  TCSETSW
#undef  TCSETSF
#define TCGETS  _IOR ('T', 8, char[36])
#define TCSETS  _IOW ('T', 9, char[36])
#define TCSETSW _IOW ('T', 10, char[36])
#define TCSETSF _IOW ('T', 11, char[36])
