Provide a UAPI version of the header in the kernel, making it easier
for interested projects to use an up-to-date version of the header.
The new headers are placed under uapi/linux/ so as not to conflict
with the glibc-provided headers in /usr/include/scsi.
/dev/sgN default values are implementation aspects, and are moved to
drivers/scsi/sg.c instead (together with e.g. SG_ALLOW_DIO_DEF).
However, SG_SCATTER_SZ is used by Wine so it is kept in linux/sg.h
SG_MAX_QUEUE could also be useful.
struct scsi_ioctl_command and struct scsi_idlun used to be under
"#ifdef __KERNEL__", but they are actually useful for userspace as
well. Add them to the new header.
