658029e0d8 Use __packed to prevent alignment from taking place, which otherwise may
change the on-disk format in an incompatible way.  Without this change,
msdosfs created on FreeBSD/arm would not be mountable.

fb95e056a5 Some cleanups from NetBSD:
- C99 initializers.
- Change the default volume label from "NO NAME" to "NO_NAME".
- Set OEM String to "BSD4.4 " following the unnamed spacing convention
  in that other OS that suggests "MSWIN4.1"
Also, David Naylor's changes for Clang, mostly changing the signess
of constants.

d461b46dd5 newfs_msdos: allow to work with media that doesn't have any CHS params
Either use parameters provided by user or make them up.
The code for faking CHS params is borrowed from disklabel code.
The logic for using user-provided and auto-guessed parameters is not
perfect, so to speak.

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.

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.
