b87d1601b6 Some useful operational extensions to newfs_msdos, especially 
when preparing images for emulators or flash devices:

+ option '-C size' to create the underlying image file with given size.
  Saves doing a 'dd' before, and especially it creates a sparse file

+ option '-@ offset' to build the FAT image at the specified offset
  in the image file or device;

+ make the cluster size adaptive on the filesystem size.
  Previously the default was 4k which is really unconvenient with
  large media; now it goes from 512 bytes to 32k depending on
  filesystem size (i still need to check whether it makes sense
  to go further up, to 64k or above);

+ fix default geometry when not specified on the command line,
  use 63 sectors/255 heads by default.
  Also trim the size so it exactly a multiple of a track, to avoid
  complaints in some filesystem code.

+ document all the above, plus some manual page clarifications.

045651ec1e Create a fake geometry (16 heads, 64 sectors) when dealing with 
a plain file and a geometry is not explicitly supplied through
command line or disktab entry.

This way you can a FAT image on a file as simply as this:

	newfs_msdos ./some/file

(right now you need a much longer command

	newfs_msdos -h 32 -u 64 -S 512 -s $total_blocks -o 0 ./some/file

Will be merged after 7.1 and 6.4 are released.
See also the related PR which suggests a similar change.

93c26a8293 The newfs_msdos utility does not store the boot signature in the 
correct place on large sector disks.  The boot signature should be at
offset 0x1fe in the BPB; newfs_msdos currently stores it 2 bytes from
the end of the sector.

d4b442791d WARNS=6 cleanup: 
- Initialize everything in the struct array, not only the mentioned
   ones
 - Unconditionally initialize hs to 0 to avoid repeatly doing so
 - Cast to unsigned int when comparing to unsigned variables.

d702a8542a Bring newfs_msdos into the GEOM world. Totally rewrite and simplify 
getdiskinfo().  For the fixed-disk case, bpb->hid probably isn't
handled correctly, but I'm not sure if this is a serious problem since
the primary use of this program is to format floppy disks.
