Bruce Evans ebedb5ad97 Cleaned up all headers that include <sys/ioctl.h> or <sys/ioccom.h>:
- don't include <sys/ioctl.h> in any header.  Include <sys/ioccom.h>
  instead.  This was already done in 4.4Lite for the most important
  ioctl headers.  Header spam currently increases kernel build
  times by 10-20%.  There are more than 30000 #includes (not counting
  duplicates) for compiling LINT.
- include <sys/types.h> if and only it is necessary to make the header
  almost self-sufficient (some ioctl headers still need structs from
  elsewhere).
- uniformized idempotency ifdefs.  Copied the style in the 4.4Lite
  ioctl headers.
