Removed sfdisk from BusyBox. It was buggy, fat, and we really couldn't

maintain it very well, so including it was not very appropriate.  Those wanting
an fdisk are invited to grab a copy from util-linux.

- * A.V. Le Blanc (LeBlanc@mcc.ac.uk) wrote Linux fdisk 1992-1994,
- * patched by various people (faith@cs.unc.edu, martin@cs.unc.edu,
- * leisner@sdsp.mc.xerox.com, esr@snark.thyrsus.com, aeb@cwi.nl)
- * 1993-1995, with version numbers (as far as I have seen) 0.93 - 2.0e.
- * This program had (head,sector,cylinder) as basic unit, and was
- * (therefore) broken in several ways for the use on larger disks -
- * for example, my last patch (from 2.0d to 2.0e) was required
- * to allow a partition to cross cylinder 8064, and to write an
- * extended partition past the 4GB mark.
- *
- * The current program is a rewrite from scratch, and I started a
- * version numbering at 3.0.
- * 	Andries Brouwer, aeb@cwi.nl, 950813
- *
- * Well, a good user interface is still lacking. On the other hand,
- * many configurations cannot be handled by any other fdisk.
- * I changed the name to sfdisk to prevent confusion. - aeb, 970501

- * Changes:
- * 19990319 - Arnaldo Carvalho de Melo <acme@conectiva.com.br> - i18n
- *
- * busyboxed by Erik Andersen <andersee@debian.org> -- I stipped out
- * all the NLS, pulled in some includes, and made stuff smaller...

- * Activate: usually one wants to have a single primary partition

- *					and the remaining ones inactive
- * Or:   sfdisk -A /dev/hda 2 5 7
- *
- * If only a single partition must be active, one may also use the form
- *       sfdisk -A2 /dev/hda

- * With "activate /dev/hda" or "sfdisk -A /dev/hda" the active partitions
- * are listed but not changed. To get zero active partitions, use
- * "activate /dev/hda none" or "sfdisk -A /dev/hda none".
- * Use something like `echo ",,,*" | sfdisk -N2 /dev/hda' to only make
