do things like:
camcontrol tur da5
or
camcontrol tur 1:2:0
or
camcontrol tur 1:2
These changes are fully backwards compatible with the original device
specification syntax (-n dev -u unit), so it is possible to use either
method to specify a device now.
The device specification changes do not affect the rescan, reset or debug
commands, since by design, those commands work on a bus or bus:target:lun
basis only.
Also, shorten the default usage statement so that it fits in a 24 column
terminal. The full usage statement is still available by using the "help"
"-h" or "-?" arguments to camcontrol.
