This may break some scripts, but with the number of ways users can damage
a system with this tool, it's important to make sure they specify which
device they want to talk to.

Allow stopping long-running commands with ^C (well, SIGINTR).
Previously this would stop the program.
directly off the drives.
This command shows a minor problem: it requires that the device nodes
exist, whereas kernel Vinum does not. Thus dumpconfig may show no
configuration for certain drives which are up and happily running.
This is documented in the man page.
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.
Describe -i option for start.
Update description of start command (will now work on plexes).
Update discussion of choice of stripe size (don't use power of 2).
Remove references to raw devices.
Add -i option to delay between blocks copied, to reduce performance
impact.
Remove -v option, things work now.
Rewrite parity maintenance functions.
Rebuildparity: Add -v option to check whether it was broken before
rebuilding each block.
