23e0012d02 Remove references to the second byte of a CCB containing the LUN, as this
is valid only for SCSI-2 and older devices.
Rename the second byte of the VERIFY CCB from 'lun' to 'byte2'.

96a93c63a8 Implement a new camcontrol function, 'camcontrol format'.
libcam/Makefile:	Add scsi_da.c to libcam for the new
			scsi_format_unit() function.

camcontrol.8:		Update the man page for the new format
			functionality, and take out the examples section
			describing how to do it with 'camcontrol cmd'.

camcontrol.c:		New format functionality.  Note that unlike the
			rest of the camcontrol subcommands, this one is
			interactive by default.  Because of the potential
			destructiveness of the format command, I thought
			it necessary to get confirmation from the user
			before spamming a disk.  You can disable the
			interactive behavior, and the status meter with
			command line arguments.

scsi_da.c:		Add the new scsi_format_unit() cdb building
			function and use #ifdef _KERNEL to make this file
			compile in both the kernel and userland.  The
			format unit function is currently only defined in
			the non-kernel case, because nothing in the kernel
			is using it.  If that changes, it should be
			un-ifdefed and compiled in both cases.

scsi_da.h:		New function declaration, CDB structure and format
			data structures.

Thanks to Nick Hibma for providing some valuable input on these changes.

0cdabce076 Various typo's.
One minor nit. The speed was displayed wrong when below 1Mb/s.

37b9efd37b Fix the CAM code so that people can compile kernels with the CD driver but
without the DA driver.

The problem was that the CD driver depended on scsi_read_write() and
scsi_start_stop(), which were defined in scsi_da.c.

I moved both functions, and their associated data structures and defines
from scsi_da.* to scsi_all.*.  This is technically the "wrong" thing to do
since those commands are really only for direct-access type devices, not
for all SCSI devices.  I think, though, that the advantage (allowing people
to compile kernels without the disk driver) outweighs any architectural
purity arguments.
