Current sbp_targ diff

[Sean Bruno]

I've been quiet lately but I had some time at BSDCAN to cleanup some of 
my firewire sbp_targ diffs and would like to get them out for review.

1.  I've added a new XPORT_FW type to sys/cam/cam_ccb.h for firewire.  I 
have added a couple of patches from RELENG_7 to my tree, but they can be 
ignored:

 } cam_xport;

2.  I've added a new file to sbp_targ(fwcsr.c) that currently only 
handles the Busy Timeout register, but will undoubtably handle more in 
the future:

3.  Finally, the code.  I'm attaching a diff, however it's pretty 
intrusive so I'm also placing a tar ball of the code on my web server at:
http://www.consultcsg.com/firewire_sbp-targ.tgz so you can review the 
entirety of the code at your leisure.


I am still working on the code at this time and will be generating even 
more intrusive patches to support SBP-2 and possibly SBP-3 soon-ish.
