Reimplement ParseArgs() with getopt()
The command-line interface is intended to be equivalent. For example,
consider this command:
$ rascsi -ID0 zero.hda -ID1 one.hda
This is no longer two pairs (ID0, zero.hda), (ID1, one.hda), but a
sequence of commands:
* -I: next disk is SCSI (not SASI)
* -D 0: next disk is device 0
* zero.hda: set up disk
* -I: next disk is SCSI (not SASI)
* -D 1: next disk is device 1
* one.hda: set up disk
Since SCSI is [now] the default, this could equivalently be:
$ rascsi -d 0 zero.hda -d 1 one.hda
