Bringing the zlib-based gzip/gunzip/zcat over to toybox is a problem for another day, but at least the tests are easy...

From 820e8e5b7c10e96664a2615d95e554069656c384 Mon Sep 17 00:00:00 2001 From: Elliott Hughes <e...@google.com> Date: Mon, 24 Apr 2017 13:29:30 -0700 Subject: [PATCH] Add the gzip/gunzip/zcat tests I wrote for toolbox gzip/gunzip/zcat.
