busybox dpkg rewrite

[Glenn McGrath <bug1@optushome.com.au>]

There are a few known bugs noted at the top of the file, so treat this 
with caution, but it should be starting to be useable.

Its a drop in replacement to the existing dpkg.c in busybox cvs.

If anyone is into hashtables and hashing algorithms id like  some 
feedback on the way ive done it, i havent used them for a practicle 
purpose pefore.
