Clean up <sys/ioctl.h>.

Browse Source 
- Just use #error when including <sys/ioctl.h> in the kernel. Code
  hasn't used this header for years now and probably doesn't compile
  anyway, because of -Werror.

- Get rid of struct ttysize, TIOCGSIZE and TIOCSSIZE. All code nowadays
  use both TIOC[GS]SIZE and TIOC[GS]WINSZ. Because we have other popular
  systems that don't implement the first, it's of little use to support
  interfaces nowadays.
