To: JBottomley; +Cc: linux-scsi, hch
A great many SCSI codes and ioctl values can be made available to userspace
in a uapi header, while the kernel-only definitions stay in scsi/scsi.h.
scsi/scsi.h also includes uapi/scsi/scsi.h so kernel code need not update
includes.

To: JBottomley; +Cc: linux-scsi, hch
Now that we have uapi/scsi/scsi.h, that is the logical place for SCSI ioctl
definitions to go. The kernel-specific stuff that remains is so little that
it can be folded into scsi/scsi.h, and scsi_ioctl.h removed.
Remove all scsi_ioctl.h #includes since they all also include scsi/scsi.h,
except for ide-floppy_ioctl.c where we just replace it with including
scsi/scsi.h.
