export bsg.h header to user-mode

[Boaz Harrosh <bharrosh@panasas.com>]

Hi TOMO.

I'm using bsg.ko to submit SG_IO version-4 commands to scsi devices
from user-mode application. (version-4 for use of bidi and varlen).

I have not found a bsg.h header in my fedora-10 distribution. Is
bsg.h exported in kernel-headers-package in latest Kernels? If not
should we, and how to do it?

Meanwhile I will manually copy it to /usr/include/linux/bsg.h and see
if I need to fix any thing so it can be compiled from user-mode.

Also do you have a small libbsg or something to make it easier for
use by application? should we maintain such a package?

Pete from the OSC osd project has his set of headers and library
which I used now. Should I clean it up and send it? Or should I just 
keep it as part of the osd project for now? what are the sas and fc
guys using?

Thanks
Boaz
