Don't make more superblock segments than we have a record of in
the superblock; and print these out as we go, like newfs.
Add am "-M" flag to specify the number of reserved segments, with a note
in the man page not to use it.

size is never a valid combination).
Updated the man page to include explicit reasonable values for fsize, bsize,
and sgs, at suggestion from Hubert Feyrer.
segment size from block size).
newfs_lfs now reads the disklabel to find segment, block, and fragment
sizes. Because reading this info from the wrong fs type could result in
very poor fs layout (e.g. ffs has "16" where the segshift would go,
resulting in 512-*megabyte* segments for 8K blocks), newfs_lfs refuses
to create a filesystem on a partition not labeled "4.4LFS".
Man pages for newfs_lfs updated to reflect this change.
also fix newfs_lfs to get rid of all sorts of useless options that applied
only to newfs_ffs. Corrected reference to the FFS paper to the reference
to the BSD-LFS paper.
