Patches to make GNU gzip and BusyBox gzip produce identical compression results

[Daniel Edgecumbe]

A discussion with eschwartz on the Arch Linux freenode IRC channel led 
to the discovery of some minor implementation details lacking in the 
BusyBox gzip applet which can cause output to differ both across GNU 
gzip and BusyBox, and different versions of BusyBox.

Please find attached three seperate patches for the solution of these 
issues.

I've also pushed the branch at
https://git.esotericnonsense.com/busybox.git/

This is a re-submission as my original e-mail was bounced due to not 
being an ML member.
