[PATCH] de-busyboxify

[Chris Lumens <clumens redhat com>]

This set of patches removes all users of busybox from anaconda.  If you're
curious about the reason for this (besides the obvious), check out bug 505639.
I'm tired of dealing with nonsense like this, so it's time for busybox to
go.

busybox.anaconda had about 250 programs linked to it.  I have replaced them
with the real versions of commands where appropriate, and removed at least
100 programs entirely.  I've checked that all the programs we call in anaconda
are still present, but these sorts of changes have the potential to break
lots of things.

If everyone likes this direction, I'll spend the day or two required to do
a scratch build, then a scratch tree, then some testing.
