phk 91ca22f3a3 Swing the axe and remove some archaic features from newfs which modern
diskdrives do neither need nor want:

	-O create a 4.3BSD format filesystem
	-d rotational delay between contiguous blocks
	-k sector 0 skew, per track
	-l hardware sector interleave
	-n number of distinguished rotational positions
	-p spare sectors per track
	-r revolutions/minute
	-t tracks/cylinder
	-x spare sectors per cylinder

No change in the produced filesystem image unless one or more of
these options were used.
