ccd component partition. Note that the ccd driver still allows partitions
of any types as components since an on-disk BSD disklabel isn't available
on some port.
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.

fields consistent. Not that it matters - a grep of syssrc shows that
these fields aren't actually used for anything and should probably be
GC'd.

According to disklabel.h, its LFS semantics are "segment shift" (log2(segment
size)), but in the code it is used nowhere, and there are even plans to
allow non-poweroftwo segment sizes, so it won't ever work.
While at this, simplify the disktab-like output routine... here, currently,
BSDFFS, BSDLFS, EX2FS and ADOS do the same, so don't duplicate the code.

to avoid clobbering the boot area when using -r, but the 4.4-Lite manual

of the old boot area so that 'disklabel -r -w' won't clobber anything,
be sure to seek to the offset of the boot area (like readlabel() does).
Otherwise, if the machine has code which looks up machine-dependent label
bits, the offset read from will be incorrect, and disklabel will end up
secretly replacing the boot area with other data (which probably doesn't
look like a boot block). The only port this currently affects is
NetBSD/arm32, because it's the only one of the three ports that use
NUMBOOT > 0 that has MD label grovelling code.
